You will need to change the lamp/bulb socket as well. These sockets have a tendency to burn out and open the circuits inside. Be sure to use the correct wattage bulb, and replace the bulb socket.
Are you asking how to replace it?
If so you must first remove the frontlower air dam, under body deflectors and the lower inner fender well to access the back of the entire lens.
You can remove the entire lamp and then remove the back of the lamp to access the bulb and socket.
Leave the lamp in the car, and gently remove all the screws that hold the back cover on. Then access the bulb and scocket.
