Electrical Issues (Radio, Dome Light, Headlights)

[Blurred Talon]

Last night I plugged my HID retro in my car and drove around a bit. Everything worked just fine apart from the lights being aimed really off.
Parked the car and went to bed, everything was still normal.

Came out to go to work today, turned on the lights to take some pictures, the headlights didn't turn on (car was off, markers/turns/brakes all work). Started the car, same thing. Shut the car off, noticed the cd player was on (aftermarket, wired correctly). I pulled the dome and radio fuse under the hood, now the radio was off. Put the fuse in for the radio and it worked fine. Headlights still don't work. Had no time to screw around so I drove to work.

Got in my car after work and now the radio is not working at all, checked the fuse, it was fine. Pulled it out and left it out for now.

Haven't had a chance to poke around with my multimeter and test light since it's dark and raining.
Does anyone have any advice?

Was the HID pulg-n-play, or did you have to wire anything? Check all the grounds first.

It was a plug and play.
It's a retro that I've been working on, not some Chinese kit, I've got them removed right now though.

To update this, I fixed it.
Put the stock headlights back on, unhooked my battery for a few minutes and then all was back to normal.
