Tethering Indicator Fixtures To Illumination Fixtures

A parking facility illumination and space indicator system includes a lighting fixture configured to emit an illumination light to illuminate a parking facility and an indicator fixture coupled to the lighting fixture by a first electrical cable. The indicator fixture is configured to indicate availability of one or more parking spaces in the parking facility. The system further includes a sensor coupled to the lighting fixture by a second electrical cable. The sensor is configured to sense availability of the one or more parking spaces for parking. The lighting fixture is configured to provide power to the indicator fixture over the first electrical cable and to the sensor over the second electrical cable. The indicator fixture indicates the availability of the one or more parking spaces based on space availability information from the sensor.
