There are 5 LED lights. The first will illuminate red when the device is "off", and green when it is "on". When "on" one of the other four will illuminate green to indicate the current run-time selection.
This wall switch may be used in single or multi-gang electrical boxes, and requires a Decora style switch plate cover (not included). The timer comes with both a white and an ivory color touchpad overlay. The switch has three-wires plus the ground wire.
