    My Plow truck is an 06 Ram 3500 diesel, I run an 8' Boss V plow which I also bought new in 06'. I'm having a problem with my head lights, only the highbeams work, when I click to low beams they don't turn on, if I have the fog lamps set to on they will turn on, ambers work fine. I checked all the wiring for loose connections and everything seems to be tight with all connectors in place. I thought maybe the bulbs went bad but I changed one with a new one and still no dice? Any suggestions before I take it to the dealer and get rapped, I know they will blame the plow harness, I'm thinking thats where the problem is comming from anyway. Thanks. Joe

    what happens when you disconnect the plow do your normal high and low work?

    any connections corroded - maybe give them a bit of dielectric grease, or fluid film?

    This is with the snow plow removed from the truck, no external lights hooked up and the plow lights switch in the off position. When the plow light switch is on neither the high or low beams work on the truck as the plow lights take over.
