Does one fuse control both headlights?
Depending on how your headlight circuit is set up, there may be one fuse or multiple fuses for the headlights. If you find a blown fuse, then replacing it may fix the problem. When replacing a blown headlight fuse, it’s important to use a new one with the same amperage rating.
Why are my high beams stuck on?
Headlight Switch is Broken
It may get stuck in position for the high beams or the switch could wear out and simply not turn the headlights on at all. If the switch is bad, replacing it with a new OEM headlight switch is typically the best answer.
Why is only one high beam not working?
The likely cause is a fuse, headlight relay, headlight switch, dimmer switch or a wiring fault. About the only cause that is an easy fix is a blown fuse. Consult your owner’s manual to locate the main fuse for the headlight circuit and replace that fuse with one having the same amp rating.
Can a bad relay cause one headlight not to work?
Most total headlight failures are caused by a bad component like a fuse, relay, or module. Wiring problems can also cause both headlights to stop working.
Where is the high beam relay located?
Usually, it is under the hood of the car. The point where your fuse panel is most likely located. On the other hand, it may also be located inside the cab of the car, this would be the case if your car comes with an interior fuse box.
Is there a fuse for high beams?
Under the hood, a fuse box holds a variety of fuses and relays hooked up to all sorts of electrical components throughout your car. If the high beam fuse has blown, it’ll need to be replaced and the circuit will need to be inspected for problems. Or, it could be a bad relay.
Why can’t I turn my high beams off?
Headlight Fuse or Relay
If a headlight fuse blows, it could cause the headlights to stop working. Most headlight systems are also designed with a relay that switches the power between low beam and high beam headlights. If this relay goes bad, it could allow power to the high beams, but not the low beams.
How do I know if my headlight relay is bad?
The most common sign of a bad headlight relay is headlights that don’t work. A headlight relay will typically fail in the open position, preventing voltage from reaching the headlights. If the low beam relay fails, the low beams won’t work.

Where is the headlight fuse located?
The front of the dash panel has a fuse panel on it.
What fuse is used for headlights?
Your average high beam (for a normal headlight) is 55 or 65 watts. In a 12 V circuit, that’s less than 6 amps nominally. If you put in a 10 amp fuse, you should be ok. I have looked at some amperage vs wire diameter charts and 20 amps seems a bit too close to the 24 amp maximum for my comfort levels.
