Mercedes light bulb sockets sold individually to your needs. They may or may not include the bulbs which are on there to show the bulb example. Some bulbs have a double filament.
Ask for details and pricing for specific colors and styles.

The brown Bakelite sockets with the twist handle have VDO on some and plain on others.

I’m listing them with a starting price of $15. I don’t have a lot of quantity so it is easier to just let me know what you need and I’ll give you the price.

Of course I have the bulbs in another listing. Again, ask questions.
