Pull the headlight out of the vehicle frame to access the light bulb sockets in the back of the headlight.
Remove the light bulb sockets from the back of the headlight by pulling them straight out by hand.
Set the headlight out of the way and replace any burned out light bulbs by removing the bulbs and inserting new ones into each socket.
Insert the light bulb sockets into the back of the replacement headlight and press the headlight into the ball sockets in the vehicle's frame until they snap into place.
Secure the long headlight jack screw into the top of the headlight with the socket wrench.
