Q: Car headlight has low beam problem

asked by on

The left headlight in my car has a low-beam malfunction.

Hello. Depending on the type of head lamp system your car has, this could be as simple as a burned out head lamp bulb. If you have a standard halogen headlamp, it is probably just a burned out bulb. Now if your car is equipped with xenon headlamps, swapping of the xenon bulbs from left to right should be done to confirm that bulb has failed. If the left lamp still won’t light up, the components will need to be swapped from left to right. This would include the ignitor and control units if possible. By swapping the parts, it will lead to a recommendation of which part to replace since xenon bulbs have a longer lifespan over regular bulbs. You may need a mechanic to swap parts around to determine what has caused your lighting issue.
