Can I drive with a burnt headlight?
In most states, it is required by law that headlights must be used from sunset to sunrise. It’s also law that a motor vehicle (unless it’s a motorcycle) must have two headlights. Therefore, if you have a headlight burned out, it is possible (and likely even probable) that you’ll get pulled over.
Can a bad headlight cause a car to burn out?
The main exception is when one headlight burns out first, goes unnoticed for some time, and then the other bulb also fails. If you suspect that the bulbs may be bad, and you own a voltmeter, you may want to start the troubleshooting procedure by checking for power at the headlights.
How do you replace a burned out headlight?
Twist the headlight and pull it backward to remove it. Rotate the back of the headlight bulb counter clockwise to release it from the plastic headlight housing. Remove the bulb by sliding it back out of the plastic housing. In some applications, the bulb will be held in a plastic assembly and will need to be pulled out to be replaced.
Why are my headlights not working in high beam?
If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb. Most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch.
What happens when you turn on the headlights?
When you turn on your headlights, that switch activates a relay. That relay, in turn, actually provides the electrical connection between your headlight bulbs and the battery. Fuses are also involved in order to provide a sacrificial failure point to protect the rest of the wiring.
What causes a headlight bulb to burn out quickly?
Don’t handle the bulb with your bare fingers. Oils can cause bulbs to burn out quickly. Handle all headlight bulbs with surgical gloves and replace any existing bulbs that may have been handled incorrectly. The problem could be in your installation process.
Is it necessary to replace a burned out headlight?
This can result in lower visibility when driving at night and may result in your getting pulled over by the police. Replacing a burned out or dim headlight isn’t very difficult on most vehicles and new headlight bulbs are usually inexpensive.

What to do if you touch a headlight bulb?
If you do touch the glass of the headlight bulb, pour some rubbing alcohol on a rag and wipe the bulb down. This will remove the oils from your skin and prolong the life of the bulb. Be sure to wipe the bulb dry after cleaning it. Holding the bulb with the rag will prevent you from touching it again. Insert the bulb into the headlight housing.
Why does one of the headlights on my car not work?
One headlight doesn’t work. This is usually caused by a burned out bulb. High intensity discharge (HID) headlights can also fail due to other associated components. Neither of the headlights work. Bulbs usually don’t burn out together, but it’s still important to rule that out by checking for power.
