Abstract
A vehicle-mounted warning light system comprises a housing containing a central light surrounded by several sets of outer lights. A controller is programmed to light the central first, and then each set of outer lights in sequence, while at the same time increasing the intensity of the lights, so that the system appears to an observer to be a single light that is getting bigger and brighter. This creates the illusion that the vehicle is travelling toward the observer faster than it actually is, thus prompting the observer to quickly yield right-of-way.

10. A method of inducing vehicles, pedestrians, and onlookers to quickly yield right-of-way to an oncoming emergency vehicle, comprising the steps of:
-
providing the vehicle with a light source and control means for varying the apparent size and brightness of the light source; and increasing the apparent size and brightness of the light source in such a way as to make the light source appear to be approaching the vehicles, pedestrians, and onlookers at a faster rate than the actual velocity of the vehicle. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
