An LED traffic signal is enhanced with a combination of a cylindrical opaque visor and a transparent cone that is placed over the lens. The visor is offset from the lens to provide a gap, an escape route for fast moving air that rushes down the cone and out the gap as described in the Bernoulli formula. Various embodiments include a wing shaped visor, a standard visor being cylindrical, and a custom visor being cylindrical.
