Quick HID question on fuse
Saturday, March 14, 2009 1:11 PM
I got some good quality HIDs that I just finished installing. Now everything is working properly. So my question is on the longevity aspect. I have a set of 15amps fuses on both front lights on the inside of the side dash. So should I stay with that amount or go bigger?
I am running 50w headlights, which is less then the stock that ran at 55w-low/ 65w-high.

What's your advice?

i do believe in some cases you need to go with a bigger fuse. i remember on my last car right after i installed my hid kit i kept blowing my fuses, went bigger and it fixed the problem. i would say go up to a 20 and you should be fine. i mean worst case scenerio is a blown fuse no? my .02 cents

well if it is that high quality of a kit, it should have a relay harness with its own fuse. it all depends on the ballast current draw.

^Yep, it does have one on the positive cable.
But the dash part?

NEVER upsize factory fuses in your vehicle. The purpose of fuses is NOT to support or protect what you are running, but to protect the wires in your car from burning up under overload. I don't think you ever what to see what a car fire looks like first hand.
Most 50 Watt HID kits require more than a 15 A fuse to support them, but if your running a relay harness (which you should be) it should be separately fused from battery. When using a relay harness, the current from the ballasts is drawn straight from the battery and the only "load" on your stock headlight fuse is the relay (almost nothing).
So if you don't have a relay harness, get one. If you do, your fine. LEAVE YOUR STOCK FUSES ALONE!!!

agreed with above. if you have a relay harness, there is almost no load on your wiring.

like 5mA.

if the fuse in the relay harness is blowing, contact the manufacturer of the kit to see what is recomended. a 20 amp fuse for 2 50 watt ballasts seems light for start up.

100watts/12volt = 8.33 amps. i think 20 amp fuse is enough lol
