Headlight gremlins Options

[john77]

My headlights have decided to randomly turn themselves on and off as I drive, which is a lot of fun at night on the I405 as drivers think some obnoxious d*ck is flashing them.

I cleaned up the grounds and all the ground wire connectors by both headlights but it’s still happening.

Could this be relay connected, or are they more a once dead completely dead kind of deal?

I thought i’d ask before I drop $20 on a new one.

For the record, I have those sealed GE led headlights, and it’s happening simultaneously to both, so I know it’s not the bulbs.

If it's the lights (both going up and down), it has to be the switch. Unless both relays have failed in the same manner at the same time (possible but remote).

If the switch is coming apart internally it will move around and could do exactly what you are describing. You may also have other issues, but I'd put money on the switch.
