Your gague lights are out because of your head unit. Take the head unit out, and cap off the "Illumination" wire. What this wire does is make sure that the lights in your car are properly lit, even when the head unit is on. Yours seems to be exposed, and not connected to another wire. Once to cut the wire, and cap it off, replace the fried fuse under your hood. I forget what it is labeled as, but it's one of the small 15A's, I believe.

As for the headlight, you can just replace the bulb as everyone else has said. Good luck.

*edit*

Oh, and also. Those wierd wires that you found were the cables that were connected to the stock CD/Tape deck that was in there before you installed your aftermarket deck. They add no addition to your problem. Just tie them down neatly, and make sure that they are out of your way.

Also, you're in L.A. I'm not too far from you. I work in La Habra. If you can't figure it out, I'll shoot you over the address to my office, and I'll fix it right up for you. Just drop me a P.M. Later.

 

ya the weird looking connectors are two standard connectors used for a outside source for audio milti cd changer/tap player like he said.
