Thanks from me too. I took the bolts out but also was cautious on just yanking it out. I'm trying to develop a better way to get trailer wiring into the hybrid other than ripping out the interior and my idea is to connect right up by the taillight.
Once you're pulling the bulb from the socket it's just 'grip it and rip it'. Give it a forceful pull. I found it easier to grip near the base and make sure my force is pushing out rather than gripping the bulb (such that if the bulb were to suddenly pop out of the socket, you'd be more likely to accidentally throw the bulb than to squeeze it)
I swear the bulb is stuck in the socket. I Gave up on it tonight and I'm going to try again with angled plyers tomorrow. I honestly had an easier time replacing my clutch in my WRX than this ridiculous bulb!
Good timing on this. My side light bulb is finicky and keeps going out (a sharp whack with the hand and its back on). I'm thinking a loose connection, so I'll be taking a look at pulling the assembly tonight.
