headlight bulb replacement

What do headlight bulbs do?

Headlight bulbs are responsible for illuminating your vehicle’s headlights. Your headlights, located on the front of your car, are designed to give you maximum visibility while driving. They light the road in front of you at night, and can be used to improve visibility during adverse weather conditions. Just as importantly, headlights make your vehicle visible to oncoming traffic, making them a vital safety feature that must be properly maintained.

How often should a headlight bulb need replacing?

This depends on the type of bulbs you have and on how much you use your headlights. Halogen bulbs will usually last for 500 - 1,000 hours, HID will need replacing after around 2,000 hours, Xenon is 10,000 hours, LED can last up to 30,000 hours.

The law, vehicle regulations and your MOT

According to UK law, drivers must have functioning headlights and must use them at night and when visibility is seriously reduced. A broken or faulty headlight puts you at risk of causing an accident and being pulled over and potentially fined by the police.

All headlamps are checked during an MOT and your car will fail if the headlights are broken or don't produce sufficient light. To save time and money be sure to check and replace your headlight bulbs regularly.

What causes a headlight bulb to break?

Headlight bulbs can break for a variety of reasons. For example, because of a blown fuse, if water has seeped into the light or over time they can simply wear out. The most important thing is that you replace the bulbs as soon as possible as it can be very dangerous to drive without them.

When should a headlight bulb be replaced?
