First I'm going to assemble the correct tools. This car requires a torx driver which is something I don't have at home. So I have a drill, some torx bits, and the replacement bulb.
Second: Put the correct bit into the drill and secure it in place. Set the drill to reverse and remove the screws.
Third: As you see my lights are recessed into the body so I need to be careful pulling the lens out.
Fourth: After pulling out the lens you need to twist it slightly to remove the bulb from the lens.
Fifth: Push in the bulb and give it a little twist to remove it from the socket.
Sixth: Replace the bulb and reverse the process.
Put the bulb socket back into the lens.
Place the lens back into the body and align the screw holes
Set the drill to drive and screw the screws back in being careful not to over tighten them as you might crack the lens.
