Why is my high beam light not working?
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 switch between high and low beams?
The high and low beams will have their own relay. The switch is only used to energize the relay, which then provides full power to the headlights. This is the device that “switches” between high and low beams.
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.
The high and low beams will have their own relay. The switch is only used to energize the relay, which then provides full power to the headlights. This is the device that “switches” between high and low beams.

How to test if your high beams work?
Connect a fused (20A) between the multifunction switch C202a-7, circuit 632 (GY/OG), harness side and the multifunction switch C202a-8, circuit 15 (RD/YE), harness side. Place the headlamp switch in the HEADLAMPS ON position. Do the high beams illuminate? Yes INSTALL a new multifunction switch. TEST the system for normal operation. No
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.
And if the circuits are energized but the bulbs don’t light up, it’s a 99% probability that the bulbs are faulty. Test for power at the headlight connectors (make you’re checking the high-beam wires, not the low-beam ones) or replace the bulbs.
Why is the high beam not working on my Silverado?
High beam not working on Silverado truck General Questions sailorNovember 3, 2008, 4:56pm #1 For a few weeks I am borrowing a Chevy Silverado truck whose high beam lights are not working and I’d like to take a try at fixing it.

What’s the difference between low and high beam headlights?
Benjamin Jerew is an ASE-certified Master Automobile Technician with over a decade of experience in auto repair, maintenance, and diagnosis. Required by law around the world, low beam and high beam headlights help you see and be seen, in all kinds of weather and at any hour of the day.
If that doesn’t work, it’s most likely that the relay that switches the system to high-beam supply has failed. If it isn’t bulb trouble or relay failure, the problem may reside in the light switch itself. To check that component, a multimeter and a wire-piercing probe are essential aids, and the mechanic will refer to your car’s wiring diagram.
Can a high beam bulb be replaced with a low beam bulb?
The mechanic can replace a high beam with a new bulb. If that doesn’t work, it’s most likely that the relay that switches the system to high-beam supply has failed. If it isn’t bulb trouble or relay failure, the problem may reside in the light switch itself.
Can a headlamp be changed to high beam?
The second thing to check is the headlamp bulb. The mechanic can replace a high beam with a new bulb. If that doesn’t work, it’s most likely that the relay that switches the system to high-beam supply has failed. If it isn’t bulb trouble or relay failure, the problem may reside in the light switch itself.
Do You Change Your Headlights from low to high beam?
Headlights do not change from low to high beam Inspection Service. Some cars may differ, but most headlights have fuses for each individual headlamp. If your headlights are functional on the low-beam setting, but won’t switch to high beams, the first thing a mechanic will check is the fuse. The second thing to check is the headlamp bulb.
Is it safe to drive with high beams on all the time?
There are some specific components to look into when you face this problem. You can still drive when the high beams are working but this is, by no means, a safe practice, especially during the nighttime. Turning your high beams on all the time will blind the oncoming drivers, increasing the risk of accidents.
Why are my low beams not working?
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. Headlights work but seem dim. The cause: Foggy lenses, worn out bulbs, or a charging system issue. Nov 9 2019
Why does my high beam work but not low beam?
High beam headlights don’t work or low beams don’t work. The cause: A burned out bulb, or a problem with the high beam switch or relay. The fix: Replace the bulb, switch, or relay. If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb.
Why are my headlights not working?
- but isn’t common if both high
- such as short circuits.
- Get familiar with the fuses and relays that control your headlights.
- Always handle Xenon HID headlights with care.
What are high beam headlights?
High beam headlights are basically designed to be used in dark areas and when traveling at higher speeds. They are usually not needed when you drive in cities and towns. It is a good idea to dim your headlights when you are driving in a city or other lighted areas with pedestrians, bicyclists , and other vehicles around.
The high beam problem should be quite simple. A single relay operates both lights, so as one comes on the fuse and relay must be OK. The 12V feed from the relay goes to one light and then over to the other, so it could be a break in the cable. The ground connection in the faulty light could be bad.
Why are the headlights on my Pelican not turning on?
1) I left them raised so the gear would get out of the way and I could reach the temperature switch. 2) After I turned them on, I disconnected the battery, and accidentally crossed the wires, causing sparks for a split second. I figured this must have blown the bulbs or the fuses, but neither of those things are broken.
Is there a relay for low beams in Pelican?
Red 1979 924 – Hmm Minerva blue 1979 924 – Where it all began! Headlights go up and down, high beams flash, but no low beams. They were intermittent for a while, then disappeared entirely. Fuses all look OK. Is there a relay for low beams?
By far the most common reason your brights will stop working is from a blown fuse or a bad relay. Or, it could be a bad relay. If the headlight relay has failed, it may not respond when you attempt to switch the high beams on. Replacing the relay should restore the system and get your high beams working once again.
Is DRL and high beam the same?
DRLs and High beam are the same. You need to buy “9005”.
Can you use LED for high beams?
No. LED headlight conversion kits are only designed to work with stock halogen bulbs and assemblies.
