How do I know if my headlight bulb is blown?
One of the first symptoms of a bad or failing headlight bulb is dim headlights. Over time headlight bulbs can wear out and begin to shine noticeably dimmer than when they were new. A dim headlight will not provide proper illumination and is also usually a sign that the bulb is approaching the end of its service life.
What happens when both headlights stop working at the same time?
You may destroy, or drastically shorten the life of, your good bulb. When both headlights stop working at the same time, the bulbs usually aren’t at fault. The main exception is when one headlight burns out first, goes unnoticed for some time, and then the other bulb also fails.
What to do if your headlight bulb is not working?
Before you write off your headlight bulb as bad, it’s important to look at the electrical connector for any signs of damage or corrosion. If the connector has come loose, pushing it back on may fix the problem. However, you’ll still want to dig a little deeper to figure out why it came loose in the first place.
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.
Why are the head and tail lights not working?
The on-board computer turns on the tail and headlights according to the light outside the car. If it is dawn or dusk the head and tail lights will come on by themselves. The light sensors also switch off the daytime lights in some latest models. When the sensor is dirty or damaged it cannot tell if it is dark or day outside.
What happens when one of the headlights is not working?
When one of the headlights is not working, the bulb of the faulty lamp may have burnt. The lifespan of bulbs is limited and this is greatly dependent on usage as well as magnitude of vibration they are exposed to. There is no way the tungsten filament in the incandescent bulb will not burn out.
Why are my high intensity discharge ( HID ) headlights not working?

What to do if your headlight doesn’t illuminate?
If the “good” bulb doesn’t illuminate, you need to take a known “good” ignitor module and connect it with the socket from the burned-out headlight that now has the “good” bulb. If the bulb lights, then you know that all you need to buy is a new ignitor module.
What should I do if my light bulb is not working?
You can switch the working bulb with the other side that is not working. If the swapped bulb works there, it is an indication that the removed bulb is bad and should be replaced. If the swapped bulb does not work, you can consider switching the ignitors.
