a visual signal to control the flow of traffic at intersections
A signal light used on highways, especially at an intersection to regulate movement of traffic. A traffic light may be set to operate as a blinker but is usually fixed, alternating red and green (and frequently including yellow as a transition between green and red) indicating stop and go (and caution).
A traffic control device that is operating and shows at least red and green in sequence. Two or more such traffic control devices at an intersection shall be counted as a single traffic light.
Traffic light, stop light
A fixed signal light alternating red and green (and frequently including yellow as a transition between green and red) used at an intersection to regulate traffic and which controls the rally vehicle. For rally purposes, only one traffic light may exist at an intersection. A traffic light may be set to operate as a blinker, although it will not be referenced as such, or may not be operating.
A series of coloured dots (or small images) found in the four corners of a pane of stamps that indicate each of the colours used to print the stamp. First used in Canada in June 1986. More recent issues have seen the use of small images relevant to the topic being commemorated, rather than "traffic lights".
A stationary signal featuring alternating red and green lights, frequently with a yellow transition light between green and red, that regulates rally traffic. Only one traffic light applies at each place where rally traffic is regulated. The signal light need not be operating or may be operating as a blinker.
