Recently my Passenger Side headlamp turned dim, while the Driver Side lamp was still bright in HI and LOW beam. I figured it was the lamp because it was over five years old. These are not OEMs, but DELTA H4 that i bought from 4WD.COM years ago. So I first replaced the headlamps because one of them had condensation inside the sealed lens. No luck, problem still persists, then I started poking around the internet and forums...came up with checking the H4 connectors, they were corroded from when I replaced the lamps, so this morning I replaced the passenger side H4 connector on the harness...and...problem persists, ****!
All I can think of now is to replace the harness with one made for the hotter burning H4 lights, like I should have done years ago when I upgraded the headlamps, had I only known to upgrade the harness at the same time.
Searching this forum, looks like a HL28200J harness from SMS is a good way to go.
Any other ideas? Or comments before I piss away another 100 bucks?
