Warning Apparatus

Abstract

A warning apparatus is provided, whose main body includes a monolithically formed transparent tempered material with a thickness. The top of the main body includes at least two injections units. The injection units are upward bumps. The injection units are less than 10 mm in height. The curvature on the surface of injection unit bumps changes at different height of the bumps. The bottom of the main body includes at least two reflection units. The reflection units are downward bumps. The bottom of the main body also includes a reflective layer attached to the outer surface of the reflection units so that the light entering the main body can be reflected by the reflective layer to provide warning. The durable, low-height injection unit bumps will minimize the impact on the driving safety when the tires run over, while providing effective visual warning.
