Can you flash your high beams?
In California, headlight flashing is legal in some situations and illegal in others. It is legal for a driver to flash his headlights to indicate intention to pass on a road which does not allow passing on the right. However, headlight flashing on multiple-lane highways is illegal.
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 do you switch between high and low beam headlamps?
In modern cars, there is a switch lever on the steering column that a driver either pushes or pulls to switch between high and low beam headlamps. The wiring has a break in some point in the system, stopping electricity from getting to the relay, switch or headlamps.
What does it mean when my headlights don’t work but my…?
What Does It Mean When My Headlights Don’t Work but My High Beams Do? When low-beam headlights do not work, but high beams are functioning correctly, the most likely cause is a bad dimmer switch. A bad dimmer switch can also result in the opposite problem, where low beams working but high beams are not.
What should I do if my headlamp is not working?
Many modern headlamps have one fuse per headlamp. If it is burned out, change it. If it’s not and the low beams work, the problem is more likely the switch, relay or wiring. By definition, a relay is an electromagnetic switch operated by a relatively small electric current that can turn on or off a much larger electric current.
Is there a problem with the Headlight high beam?
You could remove the headlight and then check the voltage at the high beam terminal when high beam is selected. If it has 12VDC then it’s a headlight bulb problem. If not…it’s a problem with the headlight high beam control.

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.
Do you need to replace high beam light bulbs?
Other headlight systems use two halogen bulbs in each headlamp — one for high beam and one for low. None of them will need to be frequently replaced, but they won’t last forever either. Some experts recommend replacing all headlight bulbs or filaments at the first sign of failure, particularly if they are original equipment.
