Abstract:
A safety light for a wheel assembly with an elastic tire section for rolling contact with a surface, comprising:an electronic circuit comprising: at least one deformation-activated switch; at least one illumination device; and at least one battery for providing electromotive power; an attachment means for attaching said electronic circuit securely to said wheel assembly; said deformation-activated switch mounted to said elastic tire section for detecting deformation in the tire and including a means to pass substantial current from said battery through said illumination device when the tire section is deformed by contact with the surface, whereby the switch is conductive for a predetermined arc portion of the wheel revolution while the switch is detecting deformation of its portion of the tire; said illumination device mounted to the wheel assembly for substantially projecting light out from said wheel assembly.
