The factory bulbs are 7440 (W21W) or wedge style 21 watt.
I know this is an old post but thanks to Whatevrworks for this writeup. I was able to get the tail/blinkers installed relatively easy and to my surprise did not have to take the rear lift gate trim panel all the way off. I only had to drop it enough on each side to get access to twist the bulb.
Of course once I dropped the panel I find the lift gate interior dome style lights were unplugged, probably by the dealer who was in there last
I also did the footwell and middle seat dome lights in LED yesterday, but didn't buy enough LEDs to do the tailgate interior light. That will be next!
