    The passenger side headlight on my Ultra Mount will only work on high beam. I have replaced the bulb, and it does the same thing. This happened last year, and I had to replace a harness becasue one of the pins had broke off, but all the pins in the plug are still intact and free of corrosion. Any suggestions?

    Double check your headlamp harness where it plugs into your trucks headlight, Make sure all the wires are seated and not corroded there. As well as the connectors on the module itself. Have you gone as far as testing the specific socket at the connector?

    3 or 4 port? Which harness did you replace last year, the one at the grill or a headlamp harness truck side?
