SOURCE: How do I replace the headlight on my VW City Golf

you should have an h7 bulb, once to take the rubber grommet behind the headlight, you will see the h7 socket, which has to wires in it, gently pull thi socket off, then there is a small wire holding the bulb in place, gently unhook the wire from the one side. and turn it to the other side and the bulb shoudl come out... replace the bulb putting it in the same way the other bulb came out.. notice the h7 bulb has a small notch on one side. it has to go in the same way or the wire will not hook back on. once it has been placed, turn the wire over the base of the bulb and hook it again, then put the socket back on the bulb and put the grommet back on the headlight.
