Thanks for the props guys! I wasn't a fan of red either at first, but after driving around with no green film or condoms for a week I was ready to try anything. Red was the only sensible choice since blue backlighting makes my red needles look like crap without something like white LEDs focused on the needle diffuser rods. Now that it's done, I really like the way it turned out.
BTW I'm not sure if it was clear in my post, but I only put the computer paper behind the gas/temp gauges. The speedo and tach worked out just fine without any diffuser at all.
Handsdown- your LEDs will still come in handy for the rest of the interior lighting! I'm kind of wishing I had more condoms right now since my HVAC, fog and window buttons are still green.
