Automatically turn your lights on & off at night. This features three settings a 4 or 6 hour timer function or a dusk till dawn. Position this after your transformer, connecting the cable to the 'Input' side and from the 'Output' side to your first light. The automatic light sensor is a must for every installation, its peace of mind turning your lights on and off for you. So simple! We recommend with every transformer should be a sensor purchased too.
The 4 & 6 hour settings will illuminate a coloured LED light on the top of the sensor whilst the Dusk till Dawn setting wont show a light at all.
