Dimmer switch failure
Hello, all. My dimmer switch on my 82 failed, it would stay on low beam, and when trying to switch into high beam, the headlights would just turn off. So i replaced the dimmer switch with a new one, and it worked for a week. But then that one failed with the same symptoms as the old one. Anyone know what exactly might be going on here? Thanks
PS: I keep high beams on normally when im driving.

This.Plus, have you considered installing headlight relays to take the load off the headlight switch and dimmer switch?

Yea I have the originals, I swapped them with some other ones. Where is the circuit breaker exactly? No corrosion at the plugs

they have a led ring on the outside that I tapped into the high beam circuit. They also take a H4 Bulb on the inside. Might be the culprit, although I don’t remember if I installed these before or after the first switch failure. I just figured LED doesn’t draw a lot so I can add it to the high beam side.
I can try this: wire the leds to the turn signals, maybe replace the h4 halogen with a led bulb. Do I have to replace the switch too?
