    HELP...headlights don\'t work

    The other night I noticed when I turned the corners My headlights got brighter....So then after I stoppped the truck, I tried to turn it back on, no power. I figured out that the postivie came off and grounded. So after replacing the starter, everything worked Except the headlights. But when I turn the brights on, all 4 work. Head lights actually have like two fillaments in them right; a high and low beam? I mean the on switch works and the bright switch works, so could I have burnt out the low beams in the 2 upper lights? Anyway so I turned on the brights and just diconnected the lower 2 lights for now. Help me out guys...Thanks

    See if there's 12 volts to the low beams when they should be on. If so, then both low beam bulbs are dead. There are 2 filaments in the low beam bulbs, one for low beam and one for high beam.
