Tail lights keep blowing out

[kuroi91]

I can't seem to figure this out, everytime i put a new 10a fuse in for my tail lights it blows. Sometimes within a day or so and tonight 2 fuses went out when i put them in in a row. A friend is telling my to put in a 15 or 20 but i dont think it's a good idea, also at the front driver side there is a green and a white wire hanging loosely down with no attachment near my highbeam.

Do those two wires have anything to do with the fuse blowing? If not what else might it be and what could i do to repair the situation?

well, a bigger fuse would stop the fuse from blowing, not too sure if it's too bad, (none of my fuses are the right size, but everythings been fine for 20K miles).

def find the other end of that green wire and attach it...a cut, loose hanging wire is never good, no matter what it is...thats general knowledge lawll

the problems with bigger fuses is the possibility of you blowing out some of your bulbs witch can be a bigger pain to swap out and could be a safty issue. before you go through that, its probably a short somewhere, check that wire and possibly else where, maybe along the length of wire which runs back to the lights, sometimes the coating rubs off and shorts out.

I had the same problem.
One of the contacts in the socket casing had melted down, creating a short circuit. I spliced in a good one from the wreckers and all is well again. Check all your bulb sockets first, it might save you a lot of work. A malfunctioning brake light switch won't cause your fuse to blow, a short will.

The fuse protects the circuitry by blowing first instead of causing a fire or making the whole circuit too hot until something fails which is supposed to be the fuse so you really don't want to use a different size fuse, even though it will work. Check for bare wires and repair it. Bare wires blow fuses and so do bad sockets. If the positive of your battery touches the negative or ground without resistance or a component in between, then infinite current is generated until something blows which doesn't take long. If you put a piece of wire, a penny or a bigger fuse in instead of the correct fuse then there is nothing to stop the infinite current and the weakest point in the circuit will catch fire. The weakest point is supposed to be the fuse and if you put a stronger one in that can handle more amps then it can cause problems, not solve them. There is a wire with a cut or worn out side and the inside wire is touching some metal somewhere making the fuse blow or could be the socket. Check a manual for the tail light wiring diagram or just remove the tail lights and follow the wire after checking the socket. You might need a multimeter to help find the short.
