It fills the entire screen with one of 8 colours of your choice. Selected by using the up/down motions of the directional navigation pad, or by simple finger-touch scrolling up/down.

Default is White (like most flashlights). But can be Grey, Blue, Red, etc. if the situation requires.

It's small, simple, yet effective. You never know when you might need to guide yourself through dark areas using your PDA.

Note:
Simply double-tap on the screen to exit the application.

I did a long hike in a forest and when it got pitch dark after sunset, PDALight was bright enough to light the path back to my car. This is a wonderful freebie!

A little improvement, is to set the Backlight to the maximum when the program start and then set the backlight to its previous state when it stop.

I found this very useful outdoors as a flashlight or night signalling device. 5 stars.
