Flashing Screen in Android

Question

I made a android project, now my project has a need to set up a alarm type, like blinking screen for which user can see that screen is blinking,

Flashing screen means, screen back light is turn off/on regularly.

Like we make a thread and after every 500 milliseconds we toggle the screen light.

How i do this...
