Water and road debris can cause these cracks to worsen, letting in more moisture which further amplifies the problem. Besides, when you drive at night, the high beam produces more light, and this will also cause your headlight to turn yellow over time.

The problem with yellow headlight bulbs is not only about their visual appeal. When your headlights are not clear, it will affect your car’s performance. It will produce less light, and this can be a safety hazard, especially when you’re driving at night.
