It's a bit fiddly but should just pull out. Make sure you're pulling the right piece though! Also sprayed the holder with silicon so as to make the job easier next time!
From memory, there is one (seemingly obvious) piece of sticky out rubber connector thingy but it's not that one! It's to the right of that piece and slightly tucked under. Wiggle it and you'll see the bulb move.
