Here is the rundown on why you dont want to do this car light thing.

Lets take 1000 watts for an example.
If you put a 1000 watt draw at 12 volts DC you will be pulling about 83 amps.
If you take that same amount of wattage on a 120 VAC circuit you will be pulling about 8.3 amps.

At 83 amps 120 volt AC for 100 feet total circuit length you would need 4 gauge wire at DC 12 it is off the charts you would spend a fortune on wire just to keep from burning the place down.
