Cape and Ray write – “LED fans are an easy way to add color to your rig, but mine are missing something crucial, a light switch. I’ve got four 120mm blue light up fans and they move some serious air. Their LEDs are pretty bright and have no problem illuminating my room a fair amount. Putting a small light switch on the LED’s lets me turn the lights off so I can sleep and keep the fans running for my hard drives. “ – Link.

Why not simply route all the LED ground connections through the switch, cutting the number of wires needed in half.
Scratch that idea, tried it and shorted out two of the 3 LEDs somehow.
