this should help.............You first remove the main stop light cluster by popping out the three bolt covers and then removing the three 10mm bolts. The cluster can then be removed to the outside of the car with a wiggle or two. You can then reach down and remove the indicator bulb holder with a bayonette action and unplug the bulb. Note: the bulb does not twist out, it pulls out of the holder. Although the holder must be twisted off in a Bayonette & Cap fashion. Good Luck!
