Why are my high beam headlights not working?

In the case of high-intensity discharge (HID) headlights, or Xenon headlights, there’s an additional component. To get the xenon and salts to plasma state, the HID generator bumps the voltage up to 30,000 V, then stabilizes around 90 V when the bulb is in operation. If the generator fails, the bulb won’t light.

How does a high beam light bulb work?

Get familiar with the fuses and relays that control your headlights. The headlight switch usually doesn’t control the headlight bulbs directly, but through one or more relays. The headlight switch powers a relay, which powers the headlight bulb. This protects the headlight switch from the high current used by the high beam headlights.

Unplug the light, pull the switch, and see if the fuse blows. If not, the problem is not in the wiring. Make sure you have purchased the correct wattage of bulb. Ensure that you do not have a faulty or damaged bulb. Check and see if your high beam bulb is the issue. If so, replace it. Check all wired connections and look for any exposed wiring.
