1. A traffic alert device comprising:
a housing having a first surface to face in a first direction toward a first area;
a directional motion sensor carried by the housing, the sensor to monitor motion in a second area different than the first area, the second area in a second direction angled relative to the first direction; and
a light emitter carried by the housing, the light emitter positioned to emit light that emanates from the first surface, the light emitter to generate a visual signal in response to the sensor detecting an object in the second area approaching the sensor, the signal to indicate a direction of movement of the object.
