Just a quick demonstration as to what $3 in LEDs, wiring, PCB boards and wall tack can do for you...
A simple wiring harness with LEDs:
I used a spare 3 pin to 4 pin fan harness for the connector (you can use any one of the ground lines, but remember yellow is 12V; also, use two pins apart to avoid accidental shorts):
2 leds per board, 2 boards in series for a total of 4 leds in series:
Simple wiring technique, just use a perf board and alternate directions for your leds. This way when you wire them, all the adjacent pins are the same polarity:
I used two strings in series for a total of 8 leds, in parallel.
What it looks like in daylight, the LEDs look blue because of poor white balance on my iphone (alternatively, this is what it would look like if I used blue LEDs!):
I think it works out pretty well. Would be brighter if I used 4 led groupings per perf board piece, and used 4 parallel strings, but it works for me, and it still is visible in CCFL lighting. Right now I'm using wall tack to hold up the leds but I'll switch to double sided foam tape when I get some. Hope this is inspiration for those of you with a DIY itch and a basic grasp of soldering and circuits.
