Thanks for the answers. I might try as well to get mine backlit. What I would like to use for that is a very little pice of fiber from a TOSLINK optical wire, drill a hole and use that to get the 'light-dot' in.

Another question I got, blue and white LED's require roughly 3.6V, other colors maybe 1.8V. Is this regulated via the resistor package Hugo was referring before ?

Wow..these white suckers are expensive!

Thanks! J.
