Nice! Have you tested to reduce the "bleed" with lighting of the digit edges in any way, either by making sure that the LED shines straight down like the white tape around the lamps, or by painting the perspex sides black or perhps by lowering the LED intensity - I've seen this on some edge lite digits of similar constructions to these?
