Abstract (en)
[origin: WO2007089228A1] A traffic signal device includes a plurality of illuminatable light assemblies such as red amber and green used to control traffic flow. A transparent element configured to fit upon the outer surface of the lens of a light assembly supports one or more opaque numerals corresponding to vehicle speed limits. The transparent member baring the speed limit numerals is placed upon the outer surface of the traffic signal lens to impose the speed limit numerals upon the light emitted by the light assembly when illuminated.
