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.
The bitterness of poor quality remains long after the sweetness of low price is forgotten.
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.
