    I tried to use my lights yesterday, and they wouldn't come on. When I looked at the fuses I noticed one of them had gotten really hot and melted the plastic casing around it, and melted the solder in the connector. I'm just glad it didn't start a fire or anything. Anybody have an idea of what could cause this? I've had the lights for over a year and never had any problems with them before.

    This exact same thing happened to me. The fuse holders that hella sends are absolute crap. Go to an auto parts store and get a new one. I happened to have 2 sets of lights so i bought two. Then splice that new one in there. I think i even put a different size fuse in it (one that could handle more load).

    As a side note. I put 100w lights in my hella 500ff and the light is incredible.

    Interested to see how this turns out.

    I think putting in a larger fuse would make the problem more dangerous. The filament that was in the 15 A fuse never failed, so it got really hot.

    Poor connection that got hot not an over load. The little plastic fuse holders are worthless for that much load. get a heavy duty ATC fuse holder. A pair of 100 watt lamps draw about 17 amps.

    I just ripped all the wiring out after it happened. I'm gonna start over with better stuff than what came with the light kit. I got a Bosch relay, heavy duty inline fuses, oem fog light switch, solder connections with shrink tubing. Gonna do it right so I never have problems again. I hate having to go back and fix stuff.

    I hooked up 4 hella black magics and had the same problem. I threw away the fuse holders from hella and replaced them with 30 amp inline fuses and bigger gage wiring. Each set of lights has its own inline fuse and relay. Seems to be fine now.
