Olight makes some of the lights discussed here. Olight specs and regular prices come from its US product pages and user manuals as of September 2026. Lux, distance and runtime figures are our arithmetic from published ratings, not measurements. This guide covers lighting only and is not legal or tactical advice.
⚡ TL;DR
Police flashlight use at a traffic stop after dark has one job: show the driver's hands and the car's interior without blinding anyone. Officers follow agency policy and training, and drivers help by turning on interior lights and keeping hands visible. On Olight's ratings, a 200-lumen medium mode already puts reading-level light on hands from 2 m.
Night stops are tense for both people. The driver sees a wall of white light in the mirror and loses sight of the road. The officer walks up to a car they cannot see into. Too much light at the wrong height makes both problems worse.
This table is the police flashlight traffic stop equipment list at a glance: each role, the type of light, the spec floor we derived in this guide, and an example.
| Role | Recommended type | Spec floor used in this guide | Example, where agency policy allows |
|---|---|---|---|
| Officer, primary handheld | Belt-carried rechargeable handheld with a tail switch | A 200-lumen mode that runs longer than the shift; a mode of 15 lumens or less | Olight Warrior 3S (Med 200 lumens, 13 hours) |
| Officer, backup or pocket light | Compact rechargeable light | 120 lumens or more for 12+ hours; lockout | Olight Baton 4 Pro (Med 120 lumens, 18 hours 30 minutes) |
| Patrol vehicle | Spotlights, takedown lights, emergency lights | Set by the agency and vehicle upfitter | Agency-installed equipment |
| Driver, during the stop | The car's own interior lights | On at night, per state driver manuals | Your dome light |
| Driver, car kit for roadside jobs | Compact rechargeable light kept out of hot sun | A low mode of about 15 lumens for close reading | Olight Baton 4 Pro |
| Flagging at night in an emergency | Flashlight with a red glow cone | As described in MUTCD Section 6D.04 | Not in the Warrior 3S or Baton 4 Pro box |

Quick Answer: Where Should a Police Flashlight Point at a Traffic Stop?
At a traffic stop, a police flashlight is used to see hands and the vehicle interior, the two things state driver manuals ask drivers to keep visible, so the useful light lands low: on laps, hands, the console and the seats. Aiming at faces adds glare and little information. Even for the patrol car's spotlight, California's training workbook says to "Pan the spotlight but avoid keeping it in one position which might blind the driver of the target vehicle."
That line comes from the California Commission on Peace Officer Standards and Training (POST) Learning Domain 22: Vehicle Pullovers workbook, Version 5.0, revised July 2025, where it appears in a list of ways to get a driver's attention before a stop. The workbook also notes that "Specific guidelines for use of emergency lighting during a vehicle pullover will be dependent upon the specific conditions of the vehicle stop and specific agency policy."
That sets the ground rule for this guide: agency policy and training decide how lights are used at a stop, and we add no tactics. We add the physics of light at close range, equipment facts from Olight's manuals and the official guidance written for drivers. Olight groups its duty-style handhelds and weapon-mounted models under tactical lights; two of those handhelds, the Warrior 3S and the Baton 4 Pro, anchor the numbers below.
Light Placement at the Window: Hands, Not Faces
At window distance, even a low mode is bright. Based on Olight's rated 23,000 candela at 2,300 lumens for the Warrior 3S, not measured, its 200-lumen Med mode puts about 2,000 lux on a surface 1 m away. That is four times the top of the 200 to 500 lux range CCOHS lists for reading good-quality print.
The math uses one rule: lux equals candela divided by distance squared. Olight publishes candela only for the peak mode, so we scaled it by lumens: 23,000 ÷ 2,300 = 10 candela per lumen. That assumes the beam keeps its shape as output drops, and inverse-square figures are rough at arm's length, so read them as orders of magnitude. The same rule sits behind every beam distance rating.
This table estimates the light landing on a target at three close distances for the Warrior 3S modes below Turbo, based on Olight's rated 23,000 candela at 2,300 lumens, not measured.
| Warrior 3S mode (Olight rating) | Estimated candela | Lux at 0.5 m | Lux at 1 m | Lux at 2 m |
|---|---|---|---|---|
| Moon, 1 lumen | 10 | 40 | 10 | 2.5 |
| Low, 15 lumens | 150 | 600 | 150 | 37.5 |
| Med, 200 lumens | 2,000 | 8,000 | 2,000 | 500 |
| High, 800 lumens | 8,000 | 32,000 | 8,000 | 2,000 |
The arithmetic is candela ÷ distance²: 2,000 ÷ 1² = 2,000 lux, 2,000 ÷ 2² = 500 lux and 8,000 ÷ 2² = 2,000 lux. Turbo is simply the rated 23,000 candela: 23,000 lux at 1 m.
The Canadian Centre for Occupational Health and Safety lighting ergonomics table, which cites the IESNA Lighting Handbook among its sources, lists 200 to 500 lux for "reading printed materials of good quality." It lists 5,000 to 10,000 lux only for "very prolonged and exacting visual tasks." Three readings follow:
- Med at 2 m lands at 500 lux, the top of the reading range, enough to see hands and read a document at the window.
- Low at 0.5 m gives about 600 lux, so 15 lumens can light a license held close.
- Turbo at 1 m gives about 23,000 lux, 46 times the top of the reading range (23,000 ÷ 500 = 46). The extra adds glare, not detail.
The useful target is the hands and the space between the seats, well below eye level. Light aimed there does the job at a fraction of the output. Olight's Warrior 3S manual puts it in capital letters: "DO NOT shine the light directly into human eyes. This may cause temporary blindness, or permanent damage to the eyes."
Safety note: Every Olight manual cited in this guide warns against shining the light into eyes. The Baton 4 Pro manual says: "Do not look directly at the light source or shine it in eyes, as this may cause temporary blindness and serious retinal damage."
How Does Strong Light Affect Drivers and Officers?
Strong light costs night vision on both sides of the window. The FAA's Aeronautical Information Manual says complete dark adaptation needs "exposure to total darkness for at least 30 minutes," and that "any degree of dark adaptation is lost within a few seconds of viewing a bright light." A driver hit by a beam, and an officer facing emergency lights, both lose some of that adaptation.
The FAA wording comes from AIM paragraph 8-1-6, Vision in Flight, written for pilots. Three groups are affected at a stop:
- The driver. A driver who has just been lit up must still pull back into traffic. The Virginia DMV Driver's Manual tells drivers to "Switch to low-beams whenever you meet oncoming traffic to avoid blinding the other driver." The same logic applies to any light aimed at a driver's eyes.
- The officer. POST's workbook adds: "Patrol officers should use caution around the patrol vehicle's emergency light so as not to temporarily impair their vision."
- Passing traffic. The workbook lists the "Level of distraction emergency lights will have on other motorists" as a factor when choosing a stop location.
A few seconds of bright light can undo half an hour of adaptation, one more reason to use the lowest mode that does the job. This guide does not cover using light against anyone's vision, and Olight's manuals warn against shining it into eyes.
Law Enforcement Lighting at a Stop: Vehicle, Handheld and Body Lights
Law enforcement lighting at a night stop runs on three layers. Vehicle-mounted spotlights and takedown lights, installed and governed by the agency, light the scene from behind. A handheld light on the officer's belt lights close detail at the window. The driver's own interior lights, which state manuals ask drivers to switch on, light the cabin from inside.
POST's high-risk pullover guidelines list emergency lights, headlights, spotlights and takedown lights as lighting equipment, so that layer comes with the patrol car, not from a flashlight catalog. The handheld layer is where a flashlight fits, and agency policies make it required kit while leaving the model to the agency. The Wichita Police Department's Policy 214 lists "Flashlight and holder" among required equipment, next to "Body-worn camera equipment." The Fargo Police Department's Policy 1023 requires a "Department issued flashlight and carrier" and says "Additional equipment must have Field Services command officer approval."
This table sets out the lighting needs for each part of a night stop, from the sources above and Olight's ratings. It is a planning aid, not a procedure.
| Sub-scenario | Who provides the light | Light level that fits | Runtime need | Water rating |
|---|---|---|---|---|
| Contact at the window | Officer handheld | About 200 to 500 lux on hands (Med at 2 m, Low at 0.5 m) | Whole shift on a medium mode | IPX8 on both Olight models here |
| Reading a license or registration | Officer handheld or the car's interior light | 200 to 500 lux (CCOHS reading range) | Seconds per stop | Not critical |
| Roadside flagging in an emergency | Flagger's flashlight with red glow cone | Per MUTCD Section 6D.04 | Length of the incident | Rain possible |
| Driver's roadside kit, after the stop | Driver's compact light | Low mode for reading, Med for a tire change | Hours, not minutes | Rain possible |
How much bright light fits in a shift? The runtime budget
A duty handheld should finish the shift on a medium mode with charge to spare, and that spare pays for brighter moments. The National Institute of Justice notes that "Some officers work four 10-hour shifts weekly or three 12-hour shifts," alongside traditional 8-hour shifts, in its summary of the shift length experiment. The question is how much High time the leftover charge buys.
The estimate treats each rated runtime as one full charge. A minute on Med uses 1/780 of the Warrior 3S charge (13 hours), and a minute in its High sequence uses 1/205 (166 + 39 minutes). If X minutes of a shift run on High and the rest on Med, the charge holds while X ÷ 205 + (shift minutes − X) ÷ 780 stays at or below 1. This table solves that for both lights, based on Olight's ratings, not measured.
| Light (Olight ratings used) | 8-hour shift | 10-hour shift | 12-hour shift |
|---|---|---|---|
| Warrior 3S: Med 200 lumens, 13 hours (780 min); High 800~248 lumens, 166 + 39 = 205 min | About 107 min of High | About 64 min of High | About 21 min of High |
| Baton 4 Pro: Med 120 lumens, 18 hours 30 minutes (1,110 min); High 600~120 lumens, 200 + 20 = 220 min | About 156 min of High | About 126 min of High | About 96 min of High |
Worked example, Warrior 3S on a 12-hour shift: Med alone uses 720 ÷ 780 = 92.3% of the charge, leaving 7.7%. Each minute moved from Med to High costs an extra 1/205 − 1/780, about 0.36% of the charge, so 7.7 ÷ 0.36 gives about 21 minutes. The model ignores cold, battery age and standby drain, so read the figures as upper bounds. The manual lists a full charge at 5.5 hours from a 5V 2A source, which fits between shifts. The Baton 4 Pro's bigger budget comes from its long Med rating.
Olight Warrior 3S: the belt light
The Olight Warrior 3S ($119.95, regular price for the Black version shown on the product page, September 2026) is a 139 mm, 176 g handheld with a tail switch and a side switch. Olight rates it at 2,300 lumens, 23,000 candela, 300 m and IPX8. Its modes: Turbo 2,300~805~253 lumens for 2.5 + 160 + 39 minutes, High 800~248 lumens for 166 + 39 minutes, Med 200 lumens for 13 hours, Low 15 lumens for 130 hours and Moon 1 lumen for 55 days. The box includes a holster, pocket clip and MCC3 magnetic cable. Olight's spec sheet lists "Law Enforcement" among its uses; that is Olight's label, not an agency approval.
The feature that matters most here is the tail switch default. The manual's factory setting is "Half press for Medium, hard press for Turbo," so a half press gives 200 lumens, not 2,300. Moon is a press-and-hold of the side switch from off. The manual adds that "Strobe and turbo mode cannot be memorized," so the light does not come back on in Turbo after a restart.
The limits are real. The manual says the specs are "test results based on ANSI/NEMA FL1-2009 Standard," older than the current FL 1-2025. It warns: "The tail switch may not work while immersed in sea water or other conductive media." It warns against repeated turbo in high temperatures, which can overheat the body. It charges only with the MCC3 cable, "not compatible with other MCC." Our duty belt setup for security guide covers where a light rides on a belt.
Olight Baton 4 Pro: the backup and the car kit light
The Olight Baton 4 Pro ($69.99, regular price for the default Matte Black CW Circuit Tree finish, September 2026) is a 111 mm, 114 g pocket light. Olight rates it at 1,600 lumens, 10,000 candela, 200 m and IPX8: Turbo 1,600~600 lumens for 2 + 198 minutes, High 600~120 lumens for 200 + 20 minutes, Med 120 lumens for 18 hours 30 minutes, Low 15 lumens for 155 hours and Moon under 1 lumen for 100 days. It charges by USB-C or MCC3, and the box includes an L stand.
Its tail button's shortcuts point at high output. The manual lists High for a press of the tail button from off, a quick double press for Turbo, and says, "Press and hold the tail button to keep Turbo; release to turn it off." For close work, start low from the side switch: from off, pressing and holding it for more than 1 second gives Moonlight.
Warning: The Baton 4 Pro manual says: "Do not store, charge, or use this light in a car where the temperature inside may exceed 60°C or in similar environments." It also says to charge "only in environments with temperatures between 0 °C and 45 °C." Keep a car-kit light out of direct sun, not on the dashboard.
A third Olight model often mentioned with duty lights, the Odin S, is a rail-mounted weapon light. Weapon-mounted lights are outside the scope of this lighting guide, and whether one is carried is an agency decision.
What Should You Do If You Get Pulled Over at Night?
If you get pulled over at night, pull over safely, turn on your interior lights and keep your hands visible on the steering wheel. The Virginia DMV Driver's Manual says: "If you are pulled over at night, turn on your vehicle's interior lights." Arkansas State Police guidance says to do it "so that the officer can see you more clearly." The interior light is the lighting tool these manuals name.
This table compares what official sources tell drivers, quoted from the source, and whether each is advice or law.
| Source | What it says about light during a traffic stop | Hands and movement | Status |
|---|---|---|---|
| Virginia DMV Driver's Manual (linked above) | "Turn on your flashers." "If you are pulled over at night, turn on your vehicle's interior lights." | "Keep your hands in plain view, preferably on the steering wheel." | Driver manual guidance |
| Arkansas State Police, in the Arkansas Driver License Study Guide (September 2024) | "If you are stopped at night, turn on the interior lights, so that the officer can see you more clearly." | "Ensure that both hands are visible to the officer as he or she approaches" | Driver manual guidance |
| North Kingstown, Rhode Island, Police traffic stop page | "Officers do not object to drivers proceeding to the nearest well-lit area." | Acknowledge the officer with flashers and reduced speed | Local police guidance |
| South Carolina H. 4631 (2012), proposed Section 56-5-755(A) | "When a motor vehicle driver is stopped by a law enforcement officer during nighttime hours, the driver immediately must turn on the vehicle's interior lights." | Not addressed | Introduced and referred to the House Judiciary Committee; not enacted |
Put together, the driver's lighting steps are short:
- Signal and stop at a safe spot out of the traffic lane, off bridges and overpasses, as Arkansas guidance advises.
- Turn on your hazard flashers and your interior lights.
- Keep your hands in plain view. Virginia's manual says that when asked for documents, "tell him where they are and reach for them slowly, keeping one hand on the steering wheel."
- Leave the interior lights on until the stop is over, then let your eyes settle before you merge.
None of these manuals mentions a driver's flashlight. The interior light does the job and keeps both hands visible; a car flashlight such as the Baton 4 Pro belongs to roadside jobs like a flat tire.
Body-Worn Cameras and Lighting
Body-worn cameras record in far less light than a flashlight makes at close range. A 2014 National Institute of Justice market survey listed minimum illumination ratings from 0.03 to 1.5 lux for the cameras that stated one. Based on Olight's rated candela, not measured, even the Warrior 3S Low mode stays above 1.5 lux out to about 10 m.
The NIJ report, Body-Worn Cameras for Criminal Justice: Market Survey (Version 1.0, March 2014), defines the lux rating as "The minimum amount of light that produces an acceptable image." It notes this rating "does not take into account any Night Mode." Cameras have changed since 2014, so treat these as the vendors' figures at the time.
This table shows how far each low Warrior 3S mode keeps the center of its beam above the strictest and loosest ratings in that survey. It uses distance = √(candela ÷ lux), based on Olight's rated 10 candela per lumen, not measured.
| Warrior 3S mode | Estimated candela | Distance above 1.5 lux | Distance above 0.03 lux |
|---|---|---|---|
| Moon, 1 lumen | 10 | √(10 ÷ 1.5) = 2.6 m | √(10 ÷ 0.03) = 18.3 m |
| Low, 15 lumens | 150 | √(150 ÷ 1.5) = 10.0 m | √(150 ÷ 0.03) = 70.7 m |
| Med, 200 lumens | 2,000 | √(2,000 ÷ 1.5) = 36.5 m | √(2,000 ÷ 0.03) = 258 m |
The takeaway is limited: across that survey's stated ratings, recording at window distance did not need high output. Whether a very bright beam washes out a given camera depends on the camera, and the survey does not test it.
Note: The Warrior 3S manual says its proximity sensor reduces brightness at level 3 or higher when it "detects an obstruction nearby," and that the sensor "may NOT work if it is blocked by water or dirt on the front lens." Keep the lens clean.
Is a 200,000 Lumen Flashlight Legal?
The vehicle lighting rules we checked target where vehicle lamps point, not how bright a handheld flashlight is. California Vehicle Code Section 24404(e) states: "No spotlamp when in use shall be directed so as to illuminate any other moving vehicle." That aim-based approach is the pattern to look for. Check your own state's code before aiming any light near a road.
Section 24404 sits in Division 12 of the California Vehicle Code, which covers vehicle equipment, and it regulates spotlamps mounted on vehicles, not handheld lights. Subsection (b) reads: "No spotlamp shall be equipped with any lamp source exceeding 32 standard candlepower or 30 watts nor project any glaring light into the eyes of an approaching driver." Subsection (d) reads: "This section does not apply to spotlamps on authorized emergency vehicles." So patrol spotlights answer to agency policy, as POST's workbook says.
Our bike light laws guide shows the same approach in nine states' bicycle lamp rules, which set visibility distances and colors, not lumen caps. For the numbers on a 200,000-lumen light, its weight, heat and illuminance at close range, see our electrician flashlight guide.
At a traffic stop, the question is where the beam goes. A 2,300-lumen Warrior 3S aimed at a driver's face creates the kind of glare California's spotlamp rule is written to prevent; the same light on Low, aimed at a lap, does not.
What Flashlight Do Police Officers Use?
Police officers use the flashlight their agency issues or approves. Wichita's Policy 214 requires a "Flashlight and holder," and Fargo's Policy 1023 requires a "Department issued flashlight and carrier." These policies name the item and its holder, not a brand or a spec, and each agency sets its own list.
For officers buying a personal light where policy allows it, look for a published runtime by mode, a water rating, a holster and a lockout. Olight labels law enforcement as a use on several current models; our Olight series explained guide lists which series carry that label and how agency approval works. Olight does not claim that any agency has standardized on its lights, and neither does this guide.
What Is a Traffic Control Light Stick?
A traffic control light stick is a handheld lighted wand, often a flashlight with a colored cone, used to signal drivers at night. The federal Manual on Uniform Traffic Control Devices (MUTCD, 11th Edition, December 2023) lets flaggers use one in emergencies: a flashlight with a red glow cone that supplements the STOP/SLOW paddle or flag, used in a set way.
MUTCD Part 6, Section 6D.04 "Flashlight for Hand-Signaling," states: "When flagging in an emergency situation at night in a non-illuminated flagger station, a flagger may use a flashlight with a red glow cone to supplement the STOP/SLOW paddle or flag." Its Standard paragraph then sets three signals:
- Stop: "To inform road users to stop, the flagger shall hold the flashlight with the left arm extended and pointed down toward the ground, and then shall slowly wave the flashlight in front of the body in a slow arc from left to right such that the arc reaches no farther than 45 degrees from vertical."
- Proceed: "To inform road users to proceed, the flagger shall point the flashlight at the vehicle's bumper, slowly aim the flashlight toward the open lane, then hold the flashlight in that position. The flagger shall not wave the flashlight."
- Alert: "To alert or slow traffic, the flagger shall point the flashlight toward oncoming traffic and quickly wave the flashlight in a Figure eight motion."
Notice where the light is aimed for stop and proceed: at the ground and the bumper, not at the windshield.
Two related rules sit nearby. Section 6D.06 states: "Except in emergency situations, flagger stations shall be illuminated when flagging is used at night." Section 6C.05 states: "When uniformed law enforcement personnel are used to direct traffic, to investigate crashes, or to handle lane closures, obstructed roadways, and disasters, high-visibility safety apparel as described in this Section shall be worn by the law enforcement personnel."
Note: Neither the Warrior 3S nor the Baton 4 Pro lists a traffic cone or wand in its package contents. If your role includes night flagging, use the device your agency or employer specifies.
What This Guide Covers, and What It Leaves Out
This guide covers lighting only: where light lands, how bright it is at close range, how long it runs and what official sources tell drivers. It does not cover approach methods, positioning, weapon use or using light against a person. Those belong to agency policy, state training standards and instructors. Where a source said nothing, we said nothing, and if your agency's policy differs, the policy wins.
Your Traffic Stop Lighting Checklist
Use this checklist to set up lighting for a police flashlight traffic stop from either side of the window. Officer items stay with equipment facts from Olight manuals and agency policy; driver items follow the state guidance quoted above. Nothing here replaces your agency's training.
For officers, before the shift:
- Confirm the light is the one your agency issues or approves, in an approved holster.
- Start the shift fully charged. On a 12-hour shift, the Warrior 3S ratings leave room for about 21 minutes of High if the rest runs on Med.
- Know your tail switch. A half press on a factory-set Warrior 3S gives 200 lumens; a single press of the Baton 4 Pro tail button gives High, and a double press or press-and-hold gives Turbo.
- Lock out lights carried in a bag. The Warrior 3S manual says to "lock out the switches if the flashlight is left unused, carried, or transported."
For drivers:
- Stop in a safe, well-lit place, with hazard flashers and interior lights on.
- Keep both hands on the steering wheel and say where your documents are before you reach.
- Keep your car flashlight for roadside jobs, out of a sun-baked cabin.
- After the stop, give your eyes a moment before you merge.
