foglight lamp - socket/holder?

[twigren]

Bought a pair of new foglights but dont really get it how to install the bulbs.
Cant get in contact with the seller so I try with you guys

Attached a photo on the reflector and tiny spring. Wonder if I miss a socket or holder, or if there are any other ways to install an old 6V bulb here?

You need something like this socket

Where did you find those?  Are they for a 52 220 also?

I believe this is the type of bulb holder you need

I believe that link is for a headlight (High/Low Beam).
The fog light has a single center contact.
Here are photos of mine.
