Is there a fuse for the high beam headlamp?
No fuse aside from the BCM mega fuse, which would affect more than just one headlamp, fuse 74 is the high beam, but for both sides, The power to the headlamps is controlled by the BCM. Sounds like either the bulbs or the wiring to the right lamp. The BCM does split the circuits to either headlamp, so it is possible there’s a fault there as well.
What happens when both headlights stop working at the same time?
You may destroy, or drastically shorten the life of, your good bulb. When both headlights stop working at the same time, the bulbs usually aren’t at fault. The main exception is when one headlight burns out first, goes unnoticed for some time, and then the other bulb also fails.
Why are my headlights not working in high beam?
If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb. Most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch.
What to do if your headlight bulb is not working?
Before you write off your headlight bulb as bad, it’s important to look at the electrical connector for any signs of damage or corrosion. If the connector has come loose, pushing it back on may fix the problem. However, you’ll still want to dig a little deeper to figure out why it came loose in the first place.

If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb. Most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch.
Where are the fuses for the low beam lights?
Your low beam fuse locations in the engine compartment fuse box are fuse #26 (15 amp) and #31 (15 amp). They are for the left side and right side low beam lights but I forget if that is facing the engine left and right or sitting in the driver’s seat left and right.
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.
What can cause a low beam headlight to be dim?
If it is, use a voltmeter to see how much power, if any, is reaching the headlights. If there is no power reaching them, there is a break in the wiring somewhere between the fuse panel and the headlights themselves. Thanks! What can cause the light to be dim except when on the high beam setting?
Do you need to replace both high and low beams?
Some vehicles use a single bulb for both high and low beams while others do not. If the high beam on the same side is also out, it may be one bulb. You do not need to purchase specific bulbs for each side, but identifying which is the blown out bulb will help you to replace it without having to start the vehicle again.

Why do high beams work but low beams don’t?
This is the most common reason we see for why a car’s high beam headlights work but the low beams don’t. The normal headlights are on far more often than the high beams, so the low beams burn out more frequently. Some vehicles have entirely different bulbs for the high beams, and other models have headlights with two different filaments.
Can a high beam light bulb be blown out on the same side?
If the high beam on the same side is also out, it may be one bulb. You do not need to purchase specific bulbs for each side, but identifying which is the blown out bulb will help you to replace it without having to start the vehicle again.

Why are both low and high beam headlights not working?
If both low and high beam not working only common thing to both is the ground wire….see diagram…verify by connecting circuit tester from positive battery terminal to ground wire in the plug once disconnected from the headlight bulb on that side….you could check yourself by checking the ground wire on the other working headlight. Any luck yet?
What should I do if my headlight is not working?
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.
Can a blown fuse cause a headlight to blow out?
No. Your headlights should be powered independently from one another and blowing out one should not have any affect on the headlight on the other side of your car. If both of your headlights are out, they may have both blown out, or there may be an electrical issue with the vehicle. A blown headlight fuse is also a likely culprit. Thanks!
What to do when your low beam headlight blows out?
You can often tell when a headlight blows out while you’re driving, but confirm which bulb has actually blown out by leaving your headlights on and getting out of the vehicle to check. Then get back in your vehicle and turn on your high beams. Some vehicles use a single bulb for both high and low beams while others do not.

Inspect your head light, head light plug, and harness. Make sure your connections can be secure and are without corrosion. While your nacelle is open, try to get a look at your passing lamp switch and it’s harness. If you do not see anything obvious, plug your headlight in while it hangs loose.
Where is the headlight plug on a Harley Davidson?
There is a shiny spot on the handlebars that indicates a clamp for an accessory mount, maybe a GPS, so I’m guessing someone powered the accessory off the headlight plug. The pin/socket that was damaged was for a yellow wire, same as the wire on the headlight plug. I bought this bike from the local Harley dealer, it was from the “executive fleet”.
No. Your headlights should be powered independently from one another and blowing out one should not have any affect on the headlight on the other side of your car.

Where is the low beam relay on a GM Truck?
The low beam relay is on the bulb side of the BCM, and so is the high beam, as it appears the high beam relay is operated by a relay on the BCM (which may not be a removable relay).

Why are my high beam lights not working?
On some vehicles, particularly those with HID headlights or solid-state circuit protection (Zener diodes or high beam circuit breakers) installing the wrong bulb might result in intermittent headlight operation or no high beams at all.
