bbrown249 Posted December 6, 2016 Share Posted December 6, 2016 I was driving last night, I hit the dimmer switch in the floor, and the lights went out. I have a 1986 Mack R600 dumptruck. Is there a fuse or relay I need to be looking for? I'm new to the trucking business so if I sound stupid, sorry!

0 MHfred Posted December 6, 2016 Share Posted December 6, 2016 When that happened to me in my pick up, both high beams or low beams (I forget which) were burned out. No problem except the bulbs.

0 Kansas farmer Posted December 7, 2016 Share Posted December 7, 2016 Most likely the dimmer switch is faulty. If you hit it a couple times did they come back on?

0 Vladislav Posted December 7, 2016 Share Posted December 7, 2016 I once did it that way either and got no lights. Found out the swich burned. Connected the wires right on it to light the low beam and made the rest of the way.
