Default Question about headlights

On my 72: I can ride around all night with my low beams on and no problems. When I switch on the high beams, they work fine for a couple minutes and then they begin to flash on and off. All 4 headlights do this. I switch back to low beams and all is well. Is my dimmer switch bad or is it a wiring problem?

That’s not normal operation. Has any of the wiring been worked on or disturbed recently? Do your hazard flashers still work correctly?

Reproduction headlight switch. If so, they are famous for doing what you are experiencing.

Simple and permanent fix, add the headlight relays. I install them on all of my vintage cars. Corvette lights stop flashing and are much brighter. Also takes the load off of that older wiring. A very sensible and inexpensive upgrade.
CF member Street Rat also has a good thread on this subject:

Thanks for the responses. Makes sense that the aftermarket headlight switch can't handle all the amperage of 4 headlights. The relays seem like a good fix.
