What is the rule for headlights high beams?
If you are driving with your high-beam lights on, you must dim them at least 500 ft from any oncoming vehicle, so you don’t blind the oncoming driver. You must use low-beam lights if you are within 200-300 ft of the vehicle you are following.

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.
