How into home-brew are you? I made a useful PWM switch to check LH2.4 and Regina idle valves using a Toko TK75005. It does all the way to 0% duty cycle (max about 89%) but you'd have to invert the output and use a P-channel mosfet, I think, to drive your instrumentation lighting ground referenced. The pot to control the brightness could be any size you want physically. My circuit is simpler, using an N-channel driver, but it switches the battery side.

Can't help with the myriad of new LEDs with integrated electronics and modular controls. I'm stuck in the 80's I guess.
