Why wont my lights work?

i have a 2003 pontiac grand am and i was in a minor car accident and my head light came out. the sockets to the bulb were detached as well. i got a new headlight but it only had the main light in it. it doesnt have the bright lights or the blinker light in it nor the sockets. after my accident my dashboard lights, tail lights, fog lights, and the lights to see what gear i am in quit working. its not a fuse. we have checked all of them. how to i make my lights work again? HELP!!!!!!!!!!!!!!!!!
