The first two photos are two different types of socket I've encountered, the third photo is the corresponding plug (which as you correctly guessed, also fits the 11/12 cab rubber tail lights). The last two photos are the sad remains of a 2-pin socket that was fitted to my C15; bolted to the rearmost crossmember, and oriented upwards (so located between the chassis and rear body).

Owen, just for clarity:
There are "pins" and there are "contacts"
SBC identifies a bulb / plug with two contacts.
SCC means the bulb or plug has one central contact.
These items have two parallel pins which means the bulb or plug can be fitted two different ways.
Im not sure about this but I believe SCC stands for single center contact. This makes sense. (to me)
However along with that goes SBC or single base contact(s)??????.. which doesn't make sense. The only conclusion I can think of is that it differentiates from a double base bulb like a festoon bulb? Anyone clarify?

Anyhow a gun tail light assy would use double contact plugs and sockets to allow for a feed and an earth return.

Then, just to stop it all being too easy "they" made (single filament) bulbs, plugs and sockets with offset pins

I think SBC stands for small bayonet cap.

Thank you for that. Adrian.
So if it's Small Bayonet Cap, what is the SCC? Small Cxxxx Cap?
I guess we need someone to post up some documented info.

SCC stands for Small Centre Contact

Images attached of a trailer connection socket (at least, that's my assumption since it's an electrical connector mounted with the tow hook) found on a C15A frame.
