I vote for clap on.

 

I use the stock harness w/ (2) ballast's (1 per headlamp)...each has a relay.

 

BUT...i dont know if anyone else is having the problems i am..its a bulb manufacturer's defect i've found...on the Bi-Xenon bulbs, when you switch to hi beam, the electromagnet sucks the bulb in, but as it does, the ceramic filament rubs against the bulb housing causing a slight delay in current, causing the bulb to throw a lamp out code, and when going from HI to LOW beam, it will flicker off for about (1) second then come back on (this is only my passenger headlamp). I dont have any pictures, but hopefully i am making sense. Anyone else have any issues like this?

 

Well, once it gets there don't forget the write-up

 

yeah i've never really cared for the headlights or tail lights idk why but they've always just made the truck look kinda werid in my opinion but its to each his own!
