The warning Beam
The Warning Beam is the most safe and convenient way to warn other drivers behind broken-down vehicle for elderly motorists. The motorist turn on the Warning beam from inside of car, installed a laser device under rear bumper projects image of red triangle on the surface of road. (The triangle image places 50 meters behind from the car)
The Warning Beam appear just like a regular warning triangle into
the behind car by optical illusion. A type of projection called Anamorphosis is used to create three dimensions when viewed from certain perspective. Therefore, the flat red triangle image appear as standing warning triangle from the view of other drivers.
In addition, the device beeps sound when other vehicle cross the warning triangle to give secondary warning.
