California Vehicle Code section 24400 sets two separate rules for passenger vehicles: your car must have at least two working headlamps mounted in the right places, and you must turn them on during darkness or inclement weather.1California Legislative Information. California Code VEH 24400 Breaking the equipment rule usually gets you a fix-it ticket. Driving with your headlamps off when the law requires them is a moving violation that adds a point to your record.
What the Statute Requires on the Vehicle
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 24400 If the vehicle was registered after January 1, 1930, those headlamps have to sit directly above or in front of the front axle.
There is also a height window. Measured from the center of the lens to the ground, every headlamp and every light source inside the assembly must sit between 22 and 54 inches off the surface the vehicle is resting on.1California Legislative Information. California Code VEH 24400 Lifted trucks and lowered cars have to stay inside that band or the vehicle is not street legal.
When You Have to Turn Them On
Subdivision (b) of the statute requires at least two headlamps lit during darkness and during inclement weather.1California Legislative Information. California Code VEH 24400 Having working headlamps is not enough; you have to use them.
What Counts as Darkness
California defines darkness in Vehicle Code 280 as the period from one-half hour after sunset to one-half hour before sunrise, plus any other time when visibility is low enough that you cannot clearly see a person or vehicle at 1,000 feet.2California Legislative Information. California Code VEH 280 A heavily overcast afternoon or a long tunnel can qualify.
What Counts as Inclement Weather
Subdivision (c) defines inclement weather two ways. The first is the same 1,000-foot visibility test. The second is any condition that forces you to run your windshield wipers continuously because of rain, mist, snow, fog, or other precipitation.1California Legislative Information. California Code VEH 24400 The wiper rule is the one that trips most drivers. Intermittent use alone does not trigger the requirement. Switching to steady operation does, and your headlamps need to come on with the wipers.
Penalties Depend on Which Part You Violated
Enforcement splits along the same line as the statute. An equipment problem under subdivision (a) is correctable. Failing to use your headlamps under subdivision (b) is behavior, and behavior is not something you fix with a receipt from an auto parts store.
Equipment Violations: The Fix-It Ticket
Under CVC 40610, an officer who finds a headlamp equipment defect generally must issue a notice to correct rather than a standard citation, unless there is fraud, persistent neglect, or an immediate safety hazard.3California Legislative Information. California Code Vehicle Code – VEH 40610 You get a written deadline, typically up to 30 days, to repair the problem and have a law enforcement officer sign off on the fix.
Once an officer signs off, you submit proof of correction to the court and pay a flat $25 fee per violation.4California Legislative Information. California Code Vehicle Code – VEH 40611 That closes the ticket. Ignore the deadline and the correctable violation converts into a standard citation with a mandatory court appearance and much higher fines.
Failing to Turn Headlamps On
Driving at night or through a rainstorm with your headlamps off is handled as an ordinary moving violation. California stacks penalty assessments, surcharges, court fees, and other add-ons on top of the base fine, which pushes the total well above the base amount. Expect to pay well over $100 once assessments are applied.
What It Does to Your Driving Record
A correctable equipment violation that you fix and clear with the $25 fee does not add a point to your California driving record. The citation shows up in the record but carries no point value, and it should not drive an insurance rate increase on its own.
A moving violation under subdivision (b) is treated differently. It typically adds one point, and that point stays visible for three years. Accumulating points can land you in the negligent operator program and lead to license suspension. Insurers can see the point and may raise your premium at renewal. The cost gap between replacing a bulb now and carrying a point for three years is why officers tend to steer equipment problems toward the fix-it route whenever they can.
Vehicles the Statute Does Not Cover the Same Way
CVC 24400 applies to motor vehicles “other than a motorcycle.”1California Legislative Information. California Code VEH 24400 Motorcycle headlamp rules live in separate Vehicle Code provisions, though the broader lighting requirement in CVC 24250 still obligates every vehicle to have its required lighting equipment turned on during darkness.5California Legislative Information. California Code VEH 24250 Vehicles registered before January 1, 1930 are exempt from the front-axle placement rule, but the 22-to-54-inch height requirement still applies to them.
Two Related Rules That Often Come Up With 24400 Stops
Headlamp color is governed by a separate statute, not by 24400 itself. Vehicle Code 25950 requires that any light visible from the front of a vehicle be white or yellow, and fog lamps are held to the same white-to-yellow range.6California Legislative Information. California Code Vehicle Code – Section 25950 Blue, purple, or other tinted bulbs are easy for officers to spot and are a straightforward equipment citation.
LED retrofit bulbs installed in housings designed for halogens are a persistent source of trouble. The federal design standard that governs headlamp housings was written around halogen filament geometry, and no replaceable LED bulb has been approved through the federal process for use in a halogen housing. Factory-sealed integral LED assemblies and newer Adaptive Driving Beam systems are the exception. In California, a non-compliant assembly can draw a fix-it ticket or fail inspection, regardless of what the packaging claims.
