Rear Stop/Tail light?

[Romcom]

Anybody know what bulb is required for the Stop/tail light on a 1995 Mk1?
It seems to be a weird offset pin type fitting and I can’t find a replacement. Would be nice to put LED’s in but I’ve no idea of the type?

Anyone able to help shed some light on this?

And... I’m an idiot. Took whole light out and had a look. Someone had forced a bulb with offset pins into the holder. Now replaced. Duh!
