PTL-S1 Traffic Lights are an integral traffic management tool for use on roadwork sites. It is intended to be used to control localized vehicular traffic flow as a safer substitute for STOP/ SLOW (lollipop) signs. It is powered by a maintenance free battery that needs to be recharged at the end of the day. It is operated via the included Remote Control which places a safe distance between the actual Traffic Light and the operator. It is supplied as a single traffic light, target board and remote.
