sept 88 production 535, i've taken many apart and resoldered new bulbs in them, the originals are incandescent and burn out. I've replaced them with the original style and i've replaced them with led's. I've taken apart at least 15 of them and they all had lights. Here's the original 9/88 ones

Here's what the bulbs look like that you have to solder the leads on.

Here's one with the led bulb and a resistor, i found out later that you can get led's with the resistor built in , much easier and more compact.

This stuff all seems so ancient to me since we've gone over it many times in the years past....

This is despite the script on the switches being opague as with the fronts. Has anyone with an early 525i had the switch apart?
