I can report that this app works on the Photon 4G, in fact it works very well.
But you have to be rooted, and the leds only work when the display is off.

The app was able to know that the phone was a Motorola device and gave a compatibility message stating...
Notes:
1-The SMS led notification includes support for Handcent, Chomp, Go SMS and SMS popup.
2-You can also give a led notification to any contact from your contact list.
3-You can set the led flash speed from very slow up to always on.
4-There is a Wimax control as well but its not enabled for some reason (maybe the paid version enables it)
5-There is a setting that allows you to put all notifications to sleep at a certain time of day (or night)
6-Also a setting to switch it off when in charge mode.
7-Other settings for
-Allows you to test all colors,
- back up your settings and restore them as well.
- language setting in Danish, French, German, English (US, or UK), Spanish, Italian and Russian.
Bottom line, awesome app. Definitively buying the paid app which is only $1.00 supporting the developer.
