Headlight Problem

[C420sailor]

Hi! I installed a Whelen UHFPOS HLF in my 98 Explorer a few months back. It has worked flawlessly until recently. I've been having some odd high beam symptoms...


-Both low beams function fine.


-With the HLF off, my left high beam illuminates and my right doesn't.


-With the HLF on, my right high beam flashes and my left doesn't illuminate.


I'm so confused. I've tried tracing the wiring along with the installation instructions/wiring diagram. Has anyone seen this before? Any ideas? Thanks!

Could be a possible bad relay on the UHFPOS, do you have power to both high beams with the HLF on?, And do you have power to the high beams with the HLF off?

Yeah, sounds like the one relay went bad...

I went through the wiring again and discovered a corroded crimp connector running from the flasher to the drivers (left) side high beam. I removed the crimp connector and soldered the connection and voila! Works perfectly again. Thanks for the suggestions though!
