Why is my high beam work but not low beam?
Most total headlight failures are caused by a bad component like a fuse, relay, or module. 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.
What would cause low beam headlights not to work?
Solution: If both headlights aren’t working, it’s unlikely that a bulb is at fault. 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.
How do I know if my low beam relay is bad?
Have an assistant turn on the headlights. If you hear the relay click, you know the coil is working, but you don’t know about the contacts. If you don’t hear the click, your relay is probably bad. The safest way to test a headlight relay is to replace it with a known good one.
Is there a fuse for low beams?
Like all electrical systems, the headlights in your vehicle have a fuse in the circuit to prevent too much electricity from reaching the bulb. There will also be a headlight relay that switches power from the low beams to the high beams. If the fuse goes bad, you likely won’t have any headlights at all.
Do low beams stay on with high beams?
Normally the low beams go off with the high beams in a cobalt. This does not affect the daytime running lights since they are always on unless you turn them off. However, if you do turn off the auto lights and then flash your high beams (for example to signal another car) both the low beams and high beams flash.
Do low beams and high beams use the same bulb?
Most modern vehicles have a single bulb with two filaments. Generally, you’ll have a standard halogen bulb for low beams, and then an HID bulb for your high beams. These are not interchangeable. Both require a different bulb (HID bulbs are significantly more expensive than halogen bulbs, as well).

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.
Should you use high beams or low beams in fog?
Don’t use high-beam headlights. They won’t shine through the fog but just reflect the light back in your eyes, making it worse for you and other drivers. Use low-beams. In really dense fog, use front fog lights in addition to your low-beams if you have them.
How much does it cost to fix high beams?

Do you need to replace both high and low beams?
