LED 3rd Brake Light Problem

So I recently bought some lug nut LED lights to replace the stock 3rd brake light on my TJ. Here is the link to the exact ones I bought:

After I initially wired them up they worked fine. It wasn't until I drove it for the first time that they stopped working and caused my stop light fuse to blow. I've replaced the fuse 3 times now and they keep blowing. I'm thinking it has something to do the lower resistance of the LEDs but I'm not sure. Any ideas?

actually, my money is on the possibility that you've shorted something out during the install. Go over the wiring again. Something is shorting to ground.

The "wiring" in question was simply cutting the + and - wires from the old light and splicing them to the 2 wires connected to the LEDs. I'll go over it again but given the possibility that the wiring is fine, any other possible causes?

Sorry to sound rude or inconsiderate or anything, but the truth simply is; you changed something, then the problem appeared. Fuses blow when the circuits are shorted out. So 99% of the time, it's either the new device or the wiring has a fault. Really that just about the only possibilities here...

That was neither rude or inconsiderate. I was just looking for something else to watch for while I checked the wiring. In any case, you were right. The wiring had shorted out where it was pinched by the spare tire. Thanks
