Hey all, in the process of upgrading the (pretty awful) stock seal halogens on our rig. I bought a set of drop-in replacement LEDs which are the normal H4 positive-switched wiring pattern (each light supports both a low and high beam). I'm trying to figure out two things:
I can setup the (inner) high beams for now with just the stock wiring, I just don't the benefit of the low beam pattern. I could solve that with a relay and some hackery, so that might be worth it.
The bigger problem is the low beams that have me very confused. In low, both high and low circuits are hot. In high beam, only low is hot but with inverted polarity (which I guess works with halogens, not so much with LEDs). At first I had assumed it perhaps was a negative switched system but then I wouldn't have two hot and one ground in the low beam setting, right? Its almost as though something is mis-wired but yet it all looks stock to me, I doubt the lights have ever been upgraded.
Anyone else run into this? Hoping its something my crap EE "skills" can handle.
