While the state's sunny days get all the attention, California's evenings are just as delightful. With mild temperatures and a plethora of places to dine, dance, and socialize within walking distance, a trip at night is just as exciting to do. For instance, there is often more traffic at night in California's major entertainment districts, and you're more likely to encounter motorists under the influence of alcohol. However, this fundamental cause of nighttime car accidents is rarely emphasized.

If you are in a headlights-related accident due to another driver's broken headlights, you could bring a personal injury claim against them. An experienced California car accident lawyer may clarify the procedure and answer legal issues during a free, no-obligation case evaluation.
Headlight-Related Dangers on California Highways
While headlights try to mitigate some of these concerns by allowing the driver to see in low-visibility situations, they can also endanger other drivers. They can cause momentary blindness and result in vehicles leaving their travel lanes. On the other hand, driving without headlights impairs the driver's eyesight and how easily other drivers can see surrounding vehicles.
Here are the most common headlight-related dangers to avoid:
1. No Headlights
Approximately half of all fatal motor vehicle accidents occur at night, dawn, or dusk. All motor vehicles, save motorcycles, are required by California law to have one headlight on each side of the vehicle's front end.
Drivers must use their headlights in the dark and in adverse weather conditions that make it difficult to distinguish a person or another motor vehicle from 1,000 feet away.
Why would someone not use headlights if they allow you to see ahead and let other vehicles see you? The most popular but unwise replies are that the street lights were bright enough to distract the motorist or that the driver's headlights went out.
2. Faulty Headlights
Driving with a damaged headlight is illegal in California because you cannot operate a vehicle without two lighted headlamps. Furthermore, having only one headlight reduces your ability to see the road and any objects in your route. In addition to providing insufficient light, faulty headlights can cause the lights to flash abruptly, causing confusion or temporarily blinding drivers.
3. Dimmed Headlights
Headlight strength varies widely between vehicles and affects a driver's ability to avoid an accident. Under ideal conditions, the average motorist needs around 1.5 seconds to react to an unexpected event (a clear, sunny day).
If a car moves at 55 miles per hour, it will cover approximately 120 feet in one and a half seconds of travel. On average, drivers will require around 144 more feet for the brakes to completely stop the vehicle.
Dim headlights, especially on the low beam level, will cause drivers to fail to see and respond to a road hazard until they cannot avoid an accident.
4. Changing to Daytime Running Lights (DRLs) or Foglights (Foglamps)
Foglamps, often known as foglights, aid drivers in seeing and navigating the road during dense fog. In wet weather, most drivers utilize their standard headlights. However, vehicles should only use their foglamps when there is fog. These lights can blind other drivers in clear, dark situations.
Similarly, some drivers travel at night with their daytime running lights (DRLs) rather than headlights. Drivers should also avoid doing this because these lights boost a car's visibility to other drivers but do not effectively illuminate the road for drivers to see well at night.
5. High-Intensity Headlights (HID)
If you've ever seen a newer model vehicle with excessively bright headlights, you've probably experienced what most motorists complain about-high-intensity headlights. These headlights first appeared in select luxury vehicles. Many more manufacturers have now followed suit.
These high-intensity headlights replicate driving situations during the day. While these lights benefit drivers with this technology installed in their vehicles, they can be dangerous to drivers in oncoming traffic lanes. According to the California Highway Patrol, the state's traffic rule requires that all headlights provide white light.
Another issue with HID headlights is the upgrades to a car is that they frequently emit blue light instead of white light. They end up shining too brightly for use on the road. So before installing them. Drivers must follow more requirements while using HID headlights in raised or lowered vehicles.
6. Colored Headlights
Although some HID, LED, or Xenon headlights appear blue, they emit a very bright white light that can appear blue compared to the yellowish tone of older-model automobile headlights.
However, as in every other state, California law prohibits using blue, green, red, or other colored bulbs. The limitation of colorful headlights is that they do generally not emit enough light to aid drivers when driving at night.
7. Street Parking with Bright Lights On
Vehicles parked along the road, in parking lots, or in private driveways with bright headlights can also cause accidents because they shine in the eyes of surrounding drivers. Drivers in California can receive a ticket for leaving their bright lights on while parked. The motorist may be held liable for any injuries or property damage that follow.
Establishing Fault in a California Headlight Crash
In terms of automotive insurance, California is a liability state. Injuries and property damage caused by insured drivers must be covered by liability insurance. If you cannot prove that the driver with the faulty headlights was the cause of the collision, the driver's liability insurance will not cover these expenses.
Determining fault in any type of accident can be challenging without understanding the specifics of the collision. Typically car accidents are caused by a combination of circumstances.
However, if the collision was caused exclusively by a problem with one of the vehicles involved headlights, the driver of that vehicle has responsibility for ensuring that their vehicle maintains proper, functional order and follows state and local traffic laws.
You can establish negligence in your case by establishing the following elements:
- The Negligent Party Owes Duty of Care: A driver's duty of care is to protect others' safety and property. Reasonable drivers would observe headlight laws to see others on the road and be seen.
- The Negligent Party Did Not Exercise Reasonable Care: This will be demonstrated by the defendant's acts that violated California's headlight regulations or impaired their ability to see or be seen on the road.
- The Breach Caused Your Headlight Accident: If it is proven beyond doubt that the accident was a headlight accident, the injuries cost the victim money and damage.
Is It Possible for Someone Else to Be Held Accountable?
Not every accident is caused by one driver or a combination of drivers. This includes headlight accidents.
If a defective headlight caused the accident, then the manufacturer and distributor of the vehicle may also be held accountable.
This is a product liability case, and it requires establishing one of three headlight flaws:
- A headlight design defect impacts the entire model.
- A defect in the lights' construction or wiring.
- A packing fault occurs when the manufacturer's instructions fail to list known and unjustifiable hazards.
Conclusion
California's headlight law is effective in reducing accident risks. The law requires drivers to turn on their headlights in certain conditions, such as poor visibility or rain. This helps ensure that drivers are more visible to other drivers and pedestrians and makes it easier for them to see the road ahead. The headlight law is just one of many laws designed to keep Californians safe on the road. It is an integral part of keeping our roads safe for everyone.

Frequently Asked Questions
What does California law actually require when it comes to using headlights at night?
Under California Vehicle Code Section 24400, drivers must use headlights from 30 minutes after sunset to 30 minutes before sunrise, and any time visibility is reduced to less than 1,000 feet due to weather, smoke, or other conditions. Every non-motorcycle vehicle must have at least two functioning white headlights — one on each side of the front of the vehicle. Violating this law is not just a traffic infraction; if that violation causes an accident, it can serve as evidence of negligence in a personal injury claim.
Can I sue someone who hit me because their headlights were broken or off?
Yes — driving with faulty or no headlights violates California Vehicle Code Section 24400, and that legal violation can establish negligence per se under California Civil Code Section 1714, meaning the other driver may be automatically considered negligent without you having to prove they acted unreasonably. You would still need to show that the headlight violation directly caused your injuries and resulting damages. A California personal injury attorney can help you build that causal link, especially using the police report, photos from the scene, and witness statements.
How long do I have to file a lawsuit after a headlight-related car accident in California?
In most California car accident cases, you have two years from the date of the collision to file a personal injury lawsuit, as established by California Code of Civil Procedure Section 335.1. However, if a government vehicle with improper headlights was involved — such as a city bus or county vehicle — you must first file a government tort claim within just six months of the incident under the California Government Code Section 911.2. Missing these deadlines typically bars you from recovering any compensation, which is why it is critical to consult an attorney as soon as possible after the accident.
What kind of compensation can I recover if a driver with bad headlights caused my accident?
If another driver's defective or absent headlights caused your accident, you may be entitled to both economic and non-economic damages under California law. Economic damages can include medical bills, future medical care, lost wages, and property damage, while non-economic damages cover pain and suffering, emotional distress, and loss of enjoyment of life. In cases involving particularly reckless behavior — such as knowingly driving with broken headlights for an extended period — California courts may also award punitive damages under California Civil Code Section 3294.
Are those super-bright blue-tinted HID headlights actually legal in California?
California Vehicle Code Section 25950 requires that all headlight bulbs emit white light, so headlights that produce a blue, red, green, or other non-white color are illegal on California roads. While some HID, LED, and Xenon headlights may appear slightly blue in contrast to older halogen bulbs, they are typically still considered compliant as long as they predominantly emit bright white light. If a driver has illegally modified their headlights with colored bulbs that blinded you and caused an accident, that Vehicle Code violation can strengthen a negligence claim against them.
What mistakes do people most often make after a headlight-related car accident that hurt their injury claim?
One of the most damaging mistakes is failing to document the other vehicle's headlight condition at the scene — specifically, whether the lights were off, flickering, colored, or visibly broken — because that evidence can disappear once the car is repaired. Many people also delay seeking medical treatment, which insurance companies use to argue that the injuries were not serious or were not caused by the accident. Finally, speaking directly with the at-fault driver's insurance adjuster without legal representation can result in a lowball settlement offer that does not account for long-term medical costs or pain and suffering.
Does California's comparative fault rule affect my claim if I was also driving without my headlights on during the accident?
Yes — California follows a pure comparative fault system under California Civil Code Section 1431.2, which means your compensation can be reduced by the percentage of fault attributed to you. For example, if a jury determines you were 30% at fault for also driving without headlights and your damages total $100,000, you would recover $70,000. Unlike some states, California's pure comparative fault rule still allows you to recover damages even if you are found to be more than 50% at fault, so it is always worth discussing your case with an attorney rather than assuming you have no claim.
