Abstract
A thoroughfare lighting device includes a housing to be attached to a thoroughfare surface, and including sidewalls that taper. A plurality of light-emitting diodes (LEDs) selectively illuminate individual lanes, including a first set of LEDs to emit a generally white light, and a second set of LEDs to emit colored light that is observable by an observer. A driver circuit operates the second set of LEDs to emit colored light illuminating a single lane indicating a condition of the individual lane. Optics may be carried by the housing and positioned in optical communication with at least a portion of the plurality of LEDs. A traffic sensor communicatively coupled to the driver circuit and configured to sense a traffic pattern and generate information regarding traffic on the associated thoroughfare. The driver circuit is configured to operate the plurality of LEDs responsive to the information generated by the traffic sensor.
