I have 2 sets of HID’s… one set for my Supra that was a Phillips kit that I bought 3+ years ago for $500. One of the bulbs went out, thats it. Grabbed one out of a factory Infinity busted headlight we had laying around the shop and its been fine.
The other kit is a ebay kit thats on my Yamaha Rhino. I couldn’t begin to tell you how much abuse I have put that Rhino through and the HIDs have never failed me. I have smashed shit, had water over the hood, balasts drenched, pressure washed them, etc… not one problem. I think they are all built in Japan/China… so why pay more for a name brand kit. I did… and ill never do it again.
I also had this issue in my Denali… but I didn’t wire them into a relay, I connected them to my existing OEM wiring. They blew out once, I put another fuse in… then they blew again, so I put a 15a in instead of the OEM 10a, never had a problem since.
My rhino is hooked up through a relay, im not sure what size fuse is in it.
