Hey there ! --
OK, so this Dim thing got me down too.
The fix I found was to update the instrument bulbs to Autometer LED based instrument lights.
You can use the stock sockets (smiths repro) and use the new LED blubs.
-- I chose green personally, but they have them in clear as well. --if you need to "dim" them back down you can color in the sides of the bulb with pentel sharpie and the light will diffuse further.
the dimmer switch on the dash is then pretty useless as LEDs are binary.
here are a couple of shots from 12-2008 when i did this.
