Ok to bump up headlight fuse from 15A to 20A? HIDs
Hey guys. Tonight I went to turn on my headlights and noticed that only my passenger one was on. Thought maybe the ballast didn't fire up right, so i shut off lights, turned back on, no go. Checked the fuses and my LH fuse was blown (15A). I am running aftermarket HIDs and have heard cases on people bumping up the fuse to 20A on other cars since the ballast has a big spike on its initial fire up. Thoughts on this? Safe?

What is the recommended fuse rating from the aftermarket HID manufacturer?
The fuse is designed to be the weakest link. Although normally a 5a increase won't cause problems it is possible it may. If it does you could end up with an electrical fire and a total lose of the car.

A fuse blows due to an excessive amp draw. What is causing the larger than normal amp draw is the concern.
I would think you might have a bad ballast. One way to check is to swap right and left and see what happens. Might not be an easy task. One way to verify.
You could have blown the bulb also.

Bad Idea - Different Reason
Stumbled across this thread looking for a blown fuse issue - If you are reading this you CAN up the fuse rating to certain bulbs that will fit the 8. I did so a few years back. I was acutely aware of the draw, amperage, wire ratings, ect. Drove the car with heavier bulbs and bigger fuses for almost 3 years. Biggest mistake. It managed to damage the inside of the headlight lens. (It partially melted it) Just the inside surface and only barely before I noticed it. I could not believe that such a small change in temp would cook the light. The already fragile mounting basket for the bulb was dry, brittle and fell apart on dis-assembly. Although the bulbs did not go out, they were warped and twisted from the heat. I am still saving up enough to get new headlight assemblies.

The simple answer is you most likely have a bad ballast.
I had the same issue when I got my HID kit. I finally swapped ballast from from one side to the other to test and the problem still exisited.
Went back and got the ballast replaced and have not had a issue since.

I had halogen, albiet they were fine, I love the look of HID bulbs, plus I got a really good deal from VLEDS with various coupons.
Mind you I will at some point do a lens retrofit to complete the conversion....once my left ******** comes out of hiding from the $700 price of a new assembly in teh event I fubar mine up lol
