#SEQUENTIAL LIGHTING FREE#
Free with every 100 lights purchased otherwise sold seperately call for quote.EP2835032A1 - Colour sequential lighting device No need to close lane to turn lights off. Add additional sequence modes for a total of 5 flash patterns. Remote control, remotely control and receive battery and impact notification from anywhere (text message and email) using Pi-Lit's Smart Work Zone technology installing app on smartphone or PC. Includes: lamp, D-bolt, D socket, and key pin.Battery: 4 alkaline D-cell batteries (not included).Traditional rugged plastic design easily attaches to barricades and traffic drums.4+ month operating battery life (4 alkaline D-cell batteries not included).Uni-directional for extended battery life and consistent mounting.Advanced warning and visibility (4,000+ feet/1220-meter visibility due to coordinated moving light).Efficient lens design for maximum brightness.One sequence flash pattern in one direction.Sequential Work zone approach lighting (warn and guide traffic).The better lighting pattern results in earlier merging and slowing, both of which reduce the chance of accidents. With the use of the optional remote-control accessory, the lights ?communicate? with one another to form a smooth, clear lighting pattern. The barricade lights can be mounted on traffic drums, vertical panels, or barricades.
Sequential barricade lights provide guidance over the typical random flashing of most lights using light patterns that can navigate traffic lane changes, delineators, equipment, and personnel. The ?moving? lights help guide drivers, providing clear direction for them when approaching construction areas or other potentially hazardous road areas. The Pi-Lit? sequential barricade light provide increased safety for workers and motorists. Sequential A/C Smart Work Zone Barricade Light
