external light Bar not working

I was replacing a broken light on my external light bar that runs over the windshield yesterday and after splicing and reconnencting the new light then rewrapping the wiring in eletrical tape, i turned on the lights and they all lit up for about 5 seconds then all four of the lights went out and now I can't get any of them to work. The rest of the cars electronics appear to be fine. Any hint as to what I did wrong?

i have little electrical experience. the original wires were gold and the new lights were silver if that matters. btw they are Hella Comet 500's

My guess would be a fuse. Are they being run through a relay?

not sure what that means, but it just occured to me that i have both wires taped together and therefore probably touching eachothers wires. could that be the problem?

Not as long as the coating is intact. I would definetly check the fuse, and if it's blown, get a heavier duty one. That's what it sounds like to me.

They were dealer installed originally. Where would I find the fuse? (behind the glovebox?) and how can I tell if it's broken?

How did you reconnect the wires?Did you use proper connectors or just wrap the twisted wires with electrical tape?Sounds to me like you accidentally touch a ground with the hot wire.

Well I matched the colors of the wires, but yeah, all I did was twist the ends of the wires together then taped them.

Step one, go out and get a proper connector, either crimp or a screwdown affair.
Step two, fuse. Take the total wattage and divide by 12 to get the min-amps then get a fuse that'll handle it. EI 4x100W 400/12=33A So you'll want atleast a 35->40A fuse.
Step 3........
Step 4 Profit!
