Hi Rog, very nice and simple conversion, is that 2nd photo your artwork? Do you print with an inkjet or colour laser? I'll send a PM - I rather like the black background and clear logo.

You mention coloured LEDs for the switches. Are they already fitted with coloured LEDs or just plain "white" bulbs? If so have you replaced with coloured so that your plain inserts illuminate in colour, or just white?

Perhaps you have a photo of them illuminated?
