Kids Non-Profit Organization is developing an app for smartphones that uses the flash and screen of the smartphone to emit a flashing light on both sides of the phone, as a beacon in the dark. The sequence of light is not disturbing, nor drains the batteries more than any other smartphone application.
By using the BLINK App when walking or jogging in the evening, you will be seen at a five times further away than without, giving drivers crucial time to stop or swerve around.
Important to note, that the BLINK App does not replace real reflexes but is a very good complement while jogging or cycling. Or as a solution when one has forgotten its reflexes.
