I tried out red leds on the dash, on the switches it looks fine but I would recommend that after removing the small green translucent square that you cut out two or three squares of equal size from one of those frosted a4 folder thingys and stick them in to help diffuse the light,as I found the led was focused just on the centre of the foglight symbol and was distractingly bright. Didn't find that the leds worked well in the clocks..I used a small red neon light (fast and furious stylee!) and it works fantastic, the dimmer switch works with it also!!! Will post some pics if anyone wants to see..
