Frequently Asked Questions

What should I do if my headlights are not working?

If your headlights are not working, the first thing you should check is the headlight switch. Make sure it is turned on and that the circuit breaker is not tripped. If the switch and circuit breaker are functioning properly, you may need to consult a wiring diagram to diagnose the issue.

What is the automatic headlight system?

The automatic headlight system is a feature that turns on and off your headlights based on the ambient light conditions. It uses sensors to detect the amount of light outside and adjusts your headlights accordingly. This feature can help improve safety while driving at night or in low-light conditions.

What is the difference between high beam and low beam headlights?

High beam headlights are used for long-range visibility and illuminating dark areas. They produce a bright, intense light that can be aimed higher than low beam headlights. Low beam headlights are used for short-range visibility and are typically used when driving on well-lit roads. They produce a softer, less intense light that is aimed lower than high beam headlights.

How do I know if my headlights are properly aligned?

Your headlights should be properly aimed to ensure maximum visibility while driving. To check if your headlights are properly aligned, park your vehicle on a level surface and shine your headlights on a wall or garage door. The brightest part of the beam should be at or below the center of the headlight lens. If your headlights are not properly aligned, you may need to adjust them using the adjustment screws located on the back of the headlight assembly.
