    might be a blown fuse somewhere?

    Probably the relay on the low beams.

    Test your relays make sure they are transfering power when the plow is hooked up if the low beam isn't working replace the relay.. Here is a link of a schematic to help you find the relay....http://www.fisherplows.com/pdf/22372_050098.pdf
