Abstract

A traffic control signal has a structure upon which traffic control indicia are formed. At least one LED (45a-45h) is formed upon the structure so as to attract attention to the indicia. The LED(s) (45a-45h) have a brightness of at least 6,000 millicandella and preferably have a brightness of between approximately 6,000 millicandella and approximately 60,000 millicandella.
