We used an off the shelf set of 20ft 2AAbattery fairy leds, with our limited (see also: none) experience in electronics we felt it safer to take this route. All of the lights are easily controled by a toggle switch, and has a fade/off feature. On the inner side of the mask I sculpted a small trenchway to accommodate the tiny leds, everything is still just dry fit so its a bit like a rats nest of cable.
Hoping to have a few hours to get everything attached down for good tomorrow.
