How often should they be replaced: Well, obviously when lights dim or burn out

For maximum driving safety, it is very important to keep a close eye on how your car lights are functioning. If a light goes out, follow these steps to replace it and continue driving safely.

In general, there are two kinds of headlamps—sealed beam and composite. Sealed beam lights are common in older cars, while composite lights are found in newer models and contain special housing with a removable halogen or xenon bulb or capsules.

More often than not, if not caused by an accident, headlights and/or capsules should be replaced in pairs. Why? Because they’re usually of the same age, so when one goes the other it also likely to go out too.

With newer composite lights, dimming can also be caused by oxidation of the outer lens – similar to cataracts in people. Replacing the entire composite assembly can be an expensive option. However, we may have less expensive options to address this… feel free to ask us.
