California headlight law lives mainly in Vehicle Code Section 24400, which requires every motor vehicle except a motorcycle to have at least two headlamps mounted on the front and to keep them lit during darkness or bad weather.1California Legislative Information. California Code VEH – Section 24400 Most violations are written as correctable “fix-it” tickets, meaning you can resolve the citation by repairing the problem and paying a $25 dismissal fee rather than the full infraction fine.2California Courts.

When You Have to Turn Your Headlights On
Subdivision (b) of Section 24400 requires headlamps during darkness and inclement weather.1California Legislative Information. California Code VEH – Section 24400 Darkness runs from half an hour after sunset to half an hour before sunrise, plus any other time visibility drops below 1,000 feet.3California Department of Motor Vehicles. Recreational Vehicles and Trailers Handbook – Equipment and Operating Controls for All Drivers
Inclement weather means either of two conditions:4California Legislative Information. California Code VEH 24400
- Weather or atmospheric conditions that keep you from clearly seeing a person or vehicle at 1,000 feet. Heavy fog, smoke, and blowing dust all qualify.
- Rain, mist, snow, fog, or any other precipitation heavy enough that your windshield wipers run continuously.
The wiper rule trips up drivers who assume headlights are only about their own vision. In a light afternoon rain you may see fine, but the point of the rule is to make your car visible to the drivers around you.
Equipment Requirements for Headlamps
Every motor vehicle other than a motorcycle needs at least two headlamps, one on each side of the front.1California Legislative Information. California Code VEH – Section 24400 Each headlamp, and every light source inside it, must sit between 22 and 54 inches above the ground, measured from the center of the lamp.4California Legislative Information. California Code VEH 24400 Factory passenger vehicles clear this easily, but if you lift a truck or install an aftermarket bumper, verify the headlamps still fall inside the window after the modification.
Headlamps and all other forward-facing lights must show white or yellow light.5California Legislative Information. California Code VEH 25950 Blue-tinted, green, and red headlamps violate the code no matter how bright or well-aimed they are. Fog lamps can fall anywhere in the white-to-yellow range.
High Beam Dimming Distances
Vehicle Code 24409 covers how you use high beams at night. You should use a beam bright enough to reveal people and vehicles at a safe distance, but you must drop to low beams in two situations:6California Legislative Information. California Code VEH – Section 24409
- Within 500 feet of oncoming traffic, to avoid blinding the approaching driver.
- Within 300 feet of a vehicle you are following, to keep glare out of their mirrors.
Both distances are shorter than most drivers estimate. At freeway speed, 500 feet passes in a few seconds, so the working habit is to dim the moment you see headlights ahead. Officers often cite high-beam violations alongside headlamp equipment problems.
Aftermarket LED and HID Bulbs
Swapping LED or HID bulbs into a housing designed for halogen is one of the most common ways drivers end up with a headlamp ticket. Under the federal lighting standard, FMVSS 108, no LED replacement bulb has been submitted to and accepted by NHTSA’s official docket for use in a halogen headlamp housing.7National Highway Traffic Safety Administration. 571.108 NCC-230201-001 LED Headlights M. Baker Dropping the bulb in makes the whole assembly non-compliant even if it looks right on the road. Package labels reading “DOT Approved” or “SAE Compliant” are misleading, because no such federal approval exists for these bulbs.
Legal LED headlamps do exist, but only as sealed “integral beam” units built with LEDs from the factory. A California officer can cite you for the non-compliant assembly at a traffic stop, and the bulb swap becomes the basis for the violation under state law.7National Highway Traffic Safety Administration. 571.108 NCC-230201-001 LED Headlights M.

How to Handle a Headlight Fix-It Ticket
Equipment infractions under Division 12 of the Vehicle Code, which includes Section 24400, are generally correctable.2California Courts. Fix-It Ticket Clearing one takes three steps:
- Fix the problem. Replace the burned-out bulb, repair the assembly, or correct whatever the officer flagged.
- Get proof of correction. A law enforcement officer or other authorized person signs the back of the ticket confirming the repair.
- Pay a $25 dismissal fee per ticket to the court along with the signed citation.2California Courts. Fix-It Ticket
Ignoring the ticket is the expensive path. An uncorrected equipment infraction is treated like any other traffic violation, and California’s penalty assessments and court fees stack on top of the base fine, multiplying what you owe.
Points on Your Driving Record
Equipment violations may carry zero or one point on your DMV record depending on whether they affect safe vehicle operation.8California Department of Motor Vehicles. Driver Negligence A headlight ticket corrected and dismissed through the fix-it process typically produces no points. If it goes uncorrected and becomes a standard conviction, a point may be added.
Points stay on your record for 36 months. Enough of them within that window can trigger the DMV’s negligent operator program and possible license suspension, and insurers pull driving records when setting premiums. For a one-point violation, a judge may allow traffic violator school to keep the conviction off your insurance record, though it still shows on your DMV record.9California Department of Motor Vehicles.
