What causes headlights to burn out quickly?
VIBRATION. Halogen bulbs and sealed beam headlights have very fine tungsten wire filaments inside that emit light when heated. Even under ideal conditions, the filament can break, leaving you in the dark. Vibration caused by driving over rough roads, potholes and bumps will reduce the filament lifespan.
Do headlight bulbs dim over time?

Why do my headlight bulbs keep blowing?
This is due to spikes of high voltage jumping through the system which in-turn blow the bulb filaments and/or headlight fuses. You can perform a simple test to check if the voltage regulator is faulty, however you’ll need another person to help you rev the engine whilst you take a multimeter reading.

Do LED headlights last longer?
LEDs operate about 90% more efficiently than incandescent bulbs, and because they generate less heat, that helps them last much longer than other types of lights. … Because LEDs are smaller than bulb-type lights, they allow more design freedom with headlights and other vehicle lights.
What is the longest lasting halogen headlight bulb?
