Why are the lights in my car dim?

Headlights are an essential component of your car. As it helps you see outside it also helps alert other drivers of your presence on the road. If your headlights seem dim, there may be an underlying problem that needs to be corrected. Below are 5 reasons why your headlight might be dim.

1. Bad Bulb:

A bad bulb is the first cause of a dim headlight to be considered. Headlights don’t blow out, they dim over time, and rarely do both headlights dim at the same rate.

2. Bad Alternator:

A common explanation for faint lights in your vehicle is a weak alternator. A damaged alternator will only cause the lights to dim or flicker when the car is on. This is because the alternator charges the battery, and if it stops charging while driving, the battery will drain. If you notice that the lights brighten and dim as the engine revs up and down, the alternator should be checked immediately. 

3. Bad Ground:

A bad ground can result in lower than required voltage being delivered to your headlight, which has a particularly pronounced effect on halogen lights. This can be caused by corroded bulb terminals or a loose or broken wire. 

4. Dirty Lens:

Headlight lenses can develop leaks, which can cause condensation to form on the inside of the plastic. This water collects dust, which over time dims the light.

5. Dying battery:   

This is another common cause of headlight flickering. Your headlights rely on power from the battery to function properly. If the battery is failing, flickering, or dimming headlights may be the result.
