New lights

I have bought new morrett lights for my focus they fit in place and the plug from the old lights plug straight in but there are other wires coming from the lights. Drivers side light has an extra brown and yellow wire and the passenger side has a fuse box with a yellow/brown and red wire coming from it. The two yellow wires can be plugged together but the brown and red wires have bare ends, your help would be greatfull thanks steve.
