Preferred Procedure: Replace bulbs with manufacturer replacement bulbs.

How do you turn on a running headlamp?

Instead of clicking a small button to dim or brighten the lamp, simply swipe up or down past sensors on the side of the housing to change intensity—it even works with gloves and sweaty hands.

What should I do if my headlight bulb burns out?

Before you take your car into the mechanic consider the following options: Don’t handle the bulb with your bare fingers. Oils can cause bulbs to burn out quickly. Handle all headlight bulbs with surgical gloves and replace any existing bulbs that may have been handled incorrectly. The problem could be in your installation process.

Why does my Head Light not light up?

If the bulb does not light up, the problem could be a corroded socket or a wiring fault, which is a problem best addressed by your mechanic. Background info: High Intensity Discharge (HID) headlight bulbs are arc lamps, like a neon sign. Instead of heating a filament to produce light, electricity arcs between two electrodes inside the bulb.
