what do you need to bring to the auto shop to have installed? headlights or foglights?

headlights are plug and play i don't see why you'd need to go to the auto shop to do that... so clarify what you're asking.

 

i was talking about headlights because someone was saying only the high and low beams are plug and play. well i obviously want all the lights to work correctly otherwise it's not cool lol. i'm just not sure what "wiring to your parking brake light" really involves, i dont' want to screw anything up
