This ad is a ‘hard-to-get’ part that's hard to find.

Coincidentally, I was at my local bike shop and there I found a lamp that much resemblance with the ad in the real B737.

The wall-back lamp works with leds and has the approximate same size and shape as the real version.

Or I have the ad in my cockpit a lot will use, I doubt it. It makes everything a bit more complete ...
