Mystery Switch

Anyone know what this is?

About the size of a window switch.

I was thinking it may be aftermarket at first, but then I noticed the tiny BMW stamp and an LK stamp in a circle on the back.

The seven prongs are identified by stamped numbers starting from top left as: 2, 7, 4, 5, (one unmarked), 1, and 3. Stamped number between prongs: 03 8313 00;

Old faded paper label on side of switch states:
US. 83 [illegible];
BMW [illegible];
1 370 097;

And I just realized that the three divets are small switches also. So it has a long bar switch on top, three in the divets, and three small buttons on bottom with the LEDs in between them.

Maybe from older 5 or 6 series? You can text me too if you prefer: 252 622-5O2O
