A traffic control device includes a housing having a display structure. The display structure includes a non-reflective support panel supporting a plurality of light emitting diode elements arranged in a configuration defining a traffic control symbol. The light emitting diode elements are high intensity limited dispersion L.E.D.'s which emit light in an attenuated angular spread about a central axis. The light emitting diode elements are supported on with their control axis generally parallel to each other and generally perpendicular to the support panel.
