Abstract:
1. A method of increasing conspicuity of a vehicle to an observer, comprising: attaching a lamp to one or more of the front, sides and rear of the vehicle, the lamp including an electric power source, a timer connected to the electric power source, a transistor connected to and driven by the timer, and one or more light emitting elements connected to the transistor; and modulating intensity of light emitted from the lamp in accordance with a difference between a persistence rate of peripheral vision of the observer and a persistence rate of foveal vision of the observer such that light from the lamp appears to be flickering when viewed in the peripheral vision of the observer and appears to be steadily illuminated when viewed in the foveal vision of the observer, thereby making the lamp and vehicle more conspicuous to the observer, while presenting the observer with an apparently steady light when the lamp and vehicle are viewed straight on.
