As in life in general, the answer is : yes and no...
The LED bulbs do dim a bit, but their response is much faster than
incandescent bulbs. They disappear very quickly so adjustment is finicky. I
am speaking of the 2 main bulbs, because the switches LEDs are so dim
already, you don't want them to light less.
For the sake of knowledge of the other listers: the urQ/CGT/4000 instrument
panel use only 2 wedge bulbs (standard type 194, but with a little
magnifying lens on the tip) to project the whole 3 watts into a red tube
that distribute the light to the IC from above. These bulbs are 18$ each
here in Canada and we were seeking a longer lasting, cheaper alternative,
hence the LED bulbs.

Only question I have is, how does this work with the light rheostat?
Does it dim/brighten with the rest of the dash or stay one intensity?
