For an 1157 bulb like the # A1157B, in order to remove the old one you'll want to gently push down on the bulb while twisting the bulb 1/4 turn counterclockwise. You should then be able to pull the bulb from the socket. When replacing the bulb, align the dual notches on the base of the replacement bulb to the grooves inside the socket.
