Time to Replace Your Car Bulbs?

How long do bulbs typically last?

Bulb life varies, so it’s important to get your vehicle inspected on a regular basis. 

What is the biggest factor that leads to bulb burn-outs?

Condensation and moisture buildup are the biggest bulb killers. Let’s face it, water and electrical devices were never meant to coexist.

Condensation can buildup inside any bulb casings, especially your headlights. Condensation may mean your tail or headlight assembly is damaged and needs replacement.

Why do you have to replace the entire headlight casing when it’s just the bulb that has burned out?

Some auto manufacturers require a brand new headlight kit to be installed rather than just replacing the bulb. And if part of your headlight casing is damaged or missing, many manufacturers don’t supply individual replacement parts for headlight housing.

This is true with popular LED lights. Any lights on a LED fixture will require the entire light assembly to be replaced. While it’s true this usually costs more than just a bulb replacement, you’ll have brand new manufacturer equipment, which is always a plus.

Replacing an entire headlight casing, sometimes, can be the best thing that happened to your headlight. The reason? A broken or missing casing part may lead to future malfunctions and burn-outs.

How can you tell if a bulb is about to burn out?

The only true indication that a bulb is about to burn out is if you notice one or both your headlights appear dimmer than normal.

How do I detect a burned out turn signal?

A turn signal that blinks faster, or one that is supposed to be on but never blinks, are both indicators. If you notice your turn signal behaving this way, that’s a warning from your car that one of the turn signal bulbs is burned out. Not all cars have these burn-out indication features though, so make be sure to inspect your vehicle periodically.

Although exterior bulb burn-outs are hard to detect while you’re driving, it’s important to check your exterior lights on a semi-regular basis. Some people go months or even years without noticing a very important bulb is burned out. Bulb replacement is a must to let other drivers know you’re there or what your intentions are when moving on the road.
