Hey, new user to the forum here,
I've got a 2004 Ninja, and I'd like to flush mount my turn signals, and I noticed two small panels next to the taillight. So, curiosity got the better of me and I opened them up, and discovered these sockets.
So I figured, why not stick my turn signals in...

The back plastic screw thing needs to be shaved down to the shape of the hole. If done properly it should fit nice and snug with out any play.
notice the plastic back screw is round.
just hack away and shave...
