The pi-lit® ‘smart flare’ incorporate an innovative radio-linked network to automatically sequence the flash. Approaching drivers see a sequentially-lit string of flares much like a runway landing strip that guides traffic around the incident or work zone. They are easy to deploy and provide advanced traffic guidance and safety for motorist and road professionals. pi-lit Sequential Safety Flares has now been granted an exemption from the Federal Motor Carrier Administration (FMCSA) to be used as warning device in lieu of warning triangles or fusee flares.
