Solar Traffic Light are commonly used to signal motorists' attention to road construction and repairs, road closures,
detours, and the like. Such Waning light may be placed atop barricades, barriers, cones, barrels, poles, and the like.
Solar Traffic Light typically include a base sized to hold batteries, a cover to the top of the base containing various
electrical components, and a light source mounted atop the cover within a diffusion lens to broaden the light source beam.
