Blink

I did not make or have any association with this app. It is strictly information that I have gathered through a test I have done. MAY CONTAIN BIASED MATERIAL

The Android app “Blink” works for Droid X (at least my Motorola Droid X)
It is an app that changes the color of your notification LED and can be customized to emails, SMS, missed calls, etc.

Colors that work: RED GREEN CYAN BLUE PURPLE

Colors that don’t work: ORANGE, YELLOW (These colors worked, but they are the same color and neither of them are true orange or yellow) The following didn’t even light up—White, Pink, Light Blue, Light Green, and Light Red.
