W126 center switches are brighter, found out why

[LandYaghtLover]

I was going to post this small but annoying question. It was about the switches used for the front heated seats, fanfare horn and rear window shade. They are bright and much more "gold" in color. I actually like them. But when I fade, they still are much brighter than the other switches.

Never got around to asking why. But today, i found out why. I have pics even though I am sure its common. These switches, and these only it appears, are lit by L.E.D.s!

I know 91 is not that long ago and LEDs have been around for some time before 1991. But I though it very, very odd considering that all the other lights appear to use a regular lamp that is dimmed to make a more yellow light appearance.

Weird. I would have thought with the "cutting" edge attitude and first to market drive, they would have used LEDs across all switches. I think I may upgrade all the switches to LED if possible. And the spider optic thing too.
