Faulty MR16 lampholders

[Johnny-G]

I've got 5 of these bleedin' things playing up in 2 light fittings and they're not the generic replaceable sized ones.
Anyone got any ideas how to service them so the lamp pins make good contact again?

replace,, only cure, mr16 lampholders notorious for burning out.

I know but these look proprietary so it's not that easy.
The complete light fittings are recessed in to what looks like a 250mm hole too so it'll be a pain replacing the whole unit
