Alarm clocks have long been known to serve its purpose, using its irritating bell or chime to wake you up at specified periods that you require. But while that is used through the traditional sense of hearing, perhaps this Glo Pillow can use eyesights and help you get up to the sudden burst of light when you sleep on them.

The features are practically the same. You set the time when you want to get up and the pillow will use its built-in LEDS which brighten gradually over a span of 40 minutes that will pull you away from your deep slumber.

It seems like a more logical solution considering the gradual awakening can gradually wake you up.
