    Have a 1991 f150 that I mounted a western conventional mount plow to. I purchased new the pump and light wiring harnesses. Went by the instructions and was a breeze to install. Turned on the lights and found drivers side lights and parking/turn lights very bright, passenger side very dim. Made sure everything was grounded.. any suggestions to repair this?:help::help:

    Start with the bulb. Also check your connections at bumper and grounds.

    replaced bulbs and also switched bulbs side to side to make sure I didnt get a defective bulb. Ran a ground wire directly from the battery to both light housings.. still drivers side bright and passengers side dim.

    Is this the old style wiring that just goes to a switch, no relays?

    This is a very simple setup, only few things can be causing or issue. Something not wired correct. A short or bad ground. Bad bulbs. Double and triple check your connections. Look for any damaged or pinched wires. Unlike the switch would cause one light to be dim. How are the truck lights working? If they are fine it will only leave the wiring after the switch.
