1. Causes of dim headlights

There are usually three reasons for the decrease in brightness.
One is the accumulation of dirt on the diffuser glass or the reflector of the lamp.
Solution: You can clean your headlights with a headlight cleaning kit or by using toothpaste and a soft cloth.

The second reason is that the battery is getting weaker. The headlight can not have enough light output due to an insufficient power supply.
Solution: replace a new battery.

Third, the wires are aged or too big, which increases the resistance and affects the power supply. This situation not only affects the performance of the headlight, but also it can even cause a fire due to overheating.
Solution: replace new wires.

2. Check the headlights

Check the headlight lens for cracks. Although the surface cracks will not affect the lighting performance, moisture will penetrate the lamps along the cracks, reducing the service life of the headlight. The calibration of the headlight light direction should not be ignored. In order to ensure driving safety, the headlight must be able to provide good forward lighting for the driving vehicle.

3. Avoid water in the headlights

When the car is driving, the water splashing from the front will generally have no effect on the lights. However, using the high-pressure water gun to wash your vehicle does affect, it because the plastic used in the fixed installation position of the headlight can only be dust-proof, not water-proof.
