    So I thought I blew a bulb the other day when the drivers side went out and only worked with the high beam on. I went and picked up a new bulb and I still have the same problem... Any guesses?

    How are your electrical connections? Are you using Dielectric grease?

    first thing i would do is unplug the plow harness from the factory harness and plug the factory harness into the bulb on that side to eliminate the truck/factory harness

    BAD GROUND... check for power with a test light available at a partst store for a buck or so. I am sure it's a corroded ground on the radiator support.

    There were some problems with headlight switches burning out on the older rams. Also they are negatively switched so keep that in mind.

    He is right... What I meant is check for power. There should be power all the time. The bulb should have 3 wires 1 hot and 2 switched ground wires one for HB and 1 for LB. Is the connector burnt. You probably have a bad connector on the bulb. One of them is probably all green with corrosion clean and apply dielectric grease.

    The problem is with the wireing that goes from the light to the box for the plow... needs to be replaced.
