Abstract: Provided is a signal violation indicator for signaling the phasing of a vehicular control signal. The vehicular control signal may have a control circuit including at least a first traffic lamp and a second traffic lamp. The signal violation indicator comprises a light assembly and a base assembly. The light assembly included a first light source in data communication with the control circuit and a second light source concentrically mounted about the first light source and in data communication with the control circuit. The base assembly is connected to the light assembly and may be mounted adjacent to the vehicular control signal. The base assembly is configured to allow for selective directional control or aiming of the light assembly. The signal violation indicator is configured such that the first and second light sources are alternately activated in coordination with phasing of respective ones of the first and second traffic lamps.
