ABSTRACT:
An automatically operated, moving illuminated display for a helmet, disposed upon the rear thereof. The display is mounted on a module which adheres to the exterior of the helmet, as by hook and loop fastener. The illuminated display is provided by a series or matrix of light emitting diodes mounted to the module. Controlling electronic circuitry, a battery cell, and one of two actuating switches are also disposed upon the module. One actuating switch, located within the helmet and connected to the module by a cable, is a contact responsive switch which is tripped when the user dons the helmet. The other switch, mounted to the module, is a light sensor, which is exposed to ambient light and is responsive to fading daylight. At a predetermined ambient light level, and when the helmet is donned, power is supplied to the controller. The controller sequentially illuminates the LED display in stages, thus creating the visual impression of motion. The display continues until the ambient light level increases, or the helmet is doffed. The combination of motion and illumination enhances visibility of a cyclist wearing the novel helmet. Motorists who would otherwise be apt to overlook the cyclist are warned of his or her presence on a roadway. The system is readily attached to an otherwise conventional helmet, and may also be used with a backpack or the like.
