    Abstract: A thoroughfare lighting device may include a housing configured to be attached to a thoroughfare surface, having a top surface, a proximal face, a distal face, and first and second opposing sidewalls, a driver circuit, a plurality of light-emitting diodes electrically coupled to the driver circuit comprising a first set of LEDs configured to emit a generally white light, and a second set of LEDs configured to emit colored light that is observable by an observer. The lighting device may also include an optic carried by the housing and positioned in optical communication with the plurality of LEDs. The color of light emitted by the second set of LEDs may be selectable to indicate a condition of the thoroughfare in a direction of travel of the observer. Additionally, the first sidewall may taper in a direction of the distal face.
