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.

Which are brighter HID or LED?

Brightness. HID headlights are the brightest on the market, and the light they emit covers a larger area than halogen and LED bulbs. In fact, the area covered by HID headlights is nearly an entire third larger than the area covered by LED headlights. HIDs are also more effective at lighting up the sides of the road.

How do you know if it’s the bulb or ballast?

How do you troubleshoot a fluorescent light bulb?
