Reel of LEDs

That should be enough for a few years. And I scored a good deal on ebay on this one. Less than 1 cent per LED. I don't know if they're ultra-bright (probably not) or ultra-efficient or ultra-low-current, but it doesn't matter. These will only be uses as your typical indicator LEDs.

I did a 3 of 3000 test and all worked. Please no discussions about whether that result actually means anything ;-)
