LED bulbs for switches etc in the dash and elsewhere

A very long time ago now I got right into replacing all manner of interior lights with LED's, but the rectangular block switches (at least the newer style ones with small pins instead of the older style ones with big pins) don't have a removable bulb holder.

Are they already made with LED illumination? Can the front faceplate be unclipped to get access to a bulb holder?

I recall using really tiny wedge lamps (286T or t5 or something like that) that I sourced from Ultraleds back when that company was really new. I think the headlight switch has a removable bulb holder and some of the other lights in the dash are fairly easy to access with the fascia off or at least moved out of the dash proper.

Why I started wondered is I need to replace the recirc switch as the one in the car I'm fixing up has lost it's detent spring-lock action. Looking at it and the spare (they're Saab p/n 95 23 846) there's no back access to the internal lamp.

Does anyone have any solutions?

It was a nice read, thanks. have you thought about installing smart led lights in the instrument cluster? It would allow us to change the brightness of the illumination and its color. What do you think of that? I’ve got this idea recently, and I want to do that in my old Volvo, which is no longer my daily car.
Just went through replacing the old filament bulbs with LED. I don't know if Volvo (and which) is using the same sockets as Saab - at least my 9-5 employs bulbs with T3, T4.2 and T4.7 sockets and I haven't found any smart LED which is making the change a little bit complicated as you have to take care of the proper polarization (there are no markings on the sockets or the settings) and you will most likely not being able to dim the panel anymore unless you replace the dimmer with a DIY solution.
