A system for detecting a vehicle traveling a designated direction of travel on a roadway includes a sign having a front surface and a back surface. The sign may include a sign boundary marker that is different in color than a color of the front surface. One or more light panels such as an LED light panel is affixed to the sign such as to its front surface. The light emitting elements may lie below a top plane of the light panel. A color of a top surface of the light panel matches a color on the front surface of the sign over which the light panel is placed. A vehicle motion detector or proximity detector is oriented in a direction and has a detection zone for detecting moving vehicles in proximity to the sign. The detector illuminates the lights of the light panel after detecting a moving vehicle in proximity to the sign.
