Can a headlight bulb burn out at the same time?
Even though both of your headlight bulbs have been exposed to the exact same conditions, they usually won’t fail at exactly the same time. So it’s actually pretty common to have one bulb burn out before the other.
What are the signs of a bad hid headlight bulb?
Signs of a bad HID headlight bulb. • HID headlight bulb flickering is the EARLIEST sign of bulb failure. • HID headlight bulb shuts off after being on for a while. Shut off is sporadic and unpredictable but happens more and more often over the next 100 hours of operation.
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.
What does it mean when your headlights don’t work?
With that in mind, it can be tremendously useful to start off by looking at whether both, or just one, of your headlights have failed, and whether or not the high or low beam mode still works. When headlights stop working, it’s usually an electrical problem or an physical issue with the bulbs themselves.

What to do when both head lights stop working at the same time?
When that happens, the operational lifespan of your headlight capsule will be severely compromised, and the only fix is to replace the headlight assembly. When both headlights stop working at the same time, the bulbs usually aren’t at fault.
Why does my brake light only work on one side?
Since the problem is only on one side, you can rule out the fuse and other parts of the circuit that are shared by both bulbs. I would look closely at the connector for the nonfunctional bulb, as it may be damaged or corroded. If the bulb looks OK, you’ll want to test for power and ground at the bulb.
What to do if your HID light bulb is not working?
The easiest way to verify that your HID headlight capsule is bad is to carefully remove both bulbs and replace the one that doesn’t work with the one that does. If the known-good bulb fails to turn on when placed in the other socket, then you’re dealing with a more complicated issue.
What happens when the light bulb is turned off?
If the bulb turns off, the ballast will automatically restart the bulb within ½ second. This happens so quickly you may not even notice that it shut off in the first place. However, as the bulb ages, it may shut off (drop its arc) more often. That can happen as many as 30 times per minute. When that occurs, the ballast tends to overheat.
What to do when your HID bulb shuts off?
If your HID bulb shuts off sporadically and unpredictably; maybe just once in a 24-hr period, try this. Turn on the HID headlights and wait for the bulb to shut off by itself. Then turn off your headlight switch and immediately turn it back on. This resets the ballast. If the bulb lights with a weak pink/purple color, it’s usually a bad bulb.
How does the ballast work on a HID bulb?
An HID ballast is a boosting transformer that converts battery voltage into the approximately 75 to 110 volts needed to maintain the arc. The ballast is designed to detect bulb shut down. If the bulb turns off, the ballast will automatically restart the bulb within ½ second.
Why is my hid headlight bulb not working?
• HID headlight bulb shuts off after being on for a while. Shut off is sporadic and unpredictable but happens more and more often over the next 100 hours of operation. Swap the problem bulb to the opposite side. If it works there without shutting off, the problem is in the ballast or ignitor.
