Seat heating switch

Hi fans,

someone has changed the lamp in the switch for a seat heating (is soldered). Which lamp must be used and where can you get it (techn. Data would also be ok)? Is it a conventional 12V bulb or an LED?
Maybe someone can help me.
Oh yes: The mirror adjustment and switch for the el. I've already repaired the window lifter. The lamps are available at Conrad, if someone is interested in the data or. Order No He'll be happy to contact you.

I'll see you then
Greetings Thomas
