So sometimes when I switch the headlights on , they will begin to oscilate, wink, blink... as one comes up the other goes down and they will continue to do this until I switch them off (they both go to the off/down position). Then if I switch them on again, they will operate normally. I've swapped relays by the headlights; but made no difference.

Any ideas or thoughts?

Check the relay's first. I had the same problem. I just cleaned the relay's and sockets with contact cleaner and they were fine after that. If that does not work, try chasing bad grounds.

Good luck.

Mine did this for a few days. Kids loved it. Made for tough driving at night.

Also rotate your fuses in the fuse holder. Sometimes crap can collect on the connections an cause resistance.

Mine corrected themselves.
