Driving with one headlight might not seem like a big deal, until you’re pulled over or involved in an accident. At West Coast Trial Lawyers, we’ve seen firsthand how something as simple as a broken headlight can become a legal and financial headache.
Whether you’re trying to avoid a ticket or wondering how a faulty headlight could affect liability after a car crash, this guide will help clarify the law and explain when it’s time to speak with a personal injury attorney.
California Vehicle Headlight Law: The Basics
Under California law, headlights must be:
- Turned on between sunset and sunrise
- Used when visibility drops below 1,000 feet due to weather
- Fully functional on both sides of the vehicle
- Capable of projecting light to a distance of at least 150 feet
You can review the full statute under California Vehicle Code § 24400.
Are You Breaking the Law by Driving with One Headlight?
In California, driving with only one functioning headlight is against the law. According to the California Vehicle Code § 24250, all vehicles must be equipped with lighting devices that are “in good working order” and used when visibility is reduced (i.e., between sunset and sunrise or during weather conditions like fog or rain).
If just one headlight is out, even temporarily, you’re no longer in compliance with state law. In some cases, this could result in a “fix-it” ticket or a more serious traffic infraction.
Legal Tip: If your vehicle defect leads to an accident, it could shift liability, making you responsible, even if the other driver was partly at fault.
Why Is Driving with One Headlight So Dangerous?
A single working headlight reduces your ability to see and makes your vehicle harder to see—especially at night or in poor weather. It can cause other drivers to misjudge your position on the road or mistake you for a motorcycle, increasing the risk of a crash.
According to the National Highway Traffic Safety Administration (NHTSA), inadequate lighting plays a role in thousands of nighttime collisions each year. That’s why California takes this issue seriously, especially in high-traffic cities like Los Angeles, San Diego, and San Francisco, where police are more likely to pull drivers over for equipment violations.
Why Motorcycles Are Allowed to Have One Headlight
The reason why motorcycles are allowed to have only headlight is because they specifically designed and legally approved to operate with a single, centrally mounted headlight. Their smaller profile was considered during DOT testing and certification and have passed all legal requirements that is required by California and Federal law.
Passenger vehicles, on the other hand, are legally required to have two working headlights due to the size, build, and overall. Any attempt to compare your sedan to a motorcycle in court won’t hold up and won’t get your ticket dismissed.
What Are the Penalties for Driving with One Headlight?
In California, being caught driving with one headlight typically results in a “correctable violation”, also known as a fix-it ticket. Here’s what you could face:
- Base fine: $25 (plus court fees, which often bring it to $150+)
- Fix-it ticket: Gives you a deadline (usually 30 days) to repair the issue and have proof signed by law enforcement.
- Repeat offenses or ignoring the ticket: May result in a moving violation or even a court appearance.
- Insurance impact: Some insurers may increase your premium if the violation is reported.
What Happens if You’re in an Accident with One Headlight?
If you’re involved in a car accident while driving with only one functioning headlight, it can be used against you in court or during an insurance claim. The other party—or their insurer—could argue that you were partially or fully at fault for failing to maintain your vehicle’s safety equipment.
This is especially critical in comparative fault states like California, where liability can be shared. That means your payout could be reduced or denied entirely, depending on how much your broken headlight contributed to the accident.

Can You Be Pulled Over for One Headlight in California?
Absolutely. California Highway Patrol (CHP) and local law enforcement officers frequently pull over drivers for vehicle equipment violations, especially at night. In high-enforcement areas like Downtown LA, Hollywood, and the Bay Area, you’re even more likely to be stopped.
Once pulled over, officers may inspect:
- Your driver’s license and registration
- Insurance status
- Any other equipment violations (e.g., illegal modifications, broken taillights, etc.)
A simple headlight issue can open the door to additional citations if other violations are discovered.
State Comparison: Headlight Laws in the West
| State | Is It Illegal to Drive with One Headlight? | Penalty Type | Fine Range |
| California | Yes | Fix-it ticket or citation | $25–$250+ |
| Arizona | Yes | Warning or fine | $50–$150 |
| Washington | Yes | Citation possible | $50–$100 |
| Nevada | Yes | Citation/fix-it ticket | $100–$200 |
Each of these states requires fully operational headlights, particularly during low-light conditions. California is among the most strictly enforced, especially in urban areas with heavy traffic.
What to Do If You Get a Fix-It Ticket for a Broken Headlight
If you’re pulled over for a broken headlight, here’s what to do:
- Stay polite and cooperative. Arguing never helps.
- Accept the fix-it ticket if offered—it’s the best-case outcome.
- Get the issue fixed within 30 days (most cases).
- Have a law enforcement officer or certified mechanic sign off on the correction.
- Return the signed form to court before the deadline to avoid further penalties.
