NOTE: If you ordered your replacement headlight from Go-Parts, it likely includes new bulbs, as many of our models do! However, in case it doesn't, simply turning the sockets counter-clockwise will allow you to pull them from the old assembly to attach to the new one! Also, be sure that the alignment guides on the back of the headlight match the length and position of those on the previous assembly - this will ensure proper lighting!
