Tried old new lights before which didn’t work. Got the wrong base for the lamp.
Additionally, as it turns out, Hue lights won’t work on 12v so that whole idea is now scrapped.

Instead of plopping out / replacing the sockets and getting new bulbs I decided to go another route.
Different housing, different (and weird, but fun) lights.

^ Heat shrink tubing, and they’re good to go.

Works. Will order more and do the rest of the spots once they arrive.
