Adamson Industries Corp., a leading provider of public safety vehicle equipment and installation services, introduces Duro-Flash, a product that is being used to replace the incendiary flare.  The Duro-Flash is used by law enforcement, fire departments, highway crews and other departments that feel a need to be able to mark vehicles, close a lane, direct traffic or make a place more visible. Duro-Flashes can also be put under a cone for higher visibility. The Duro-Flash was made with longevity in mind. It has no switches or moving parts to break off or become damaged. It is water and weatherproof. Its lithium battery lasts for hours between charges. The on/off switch has been incorporated into the recharge design -- plug it in to turn it off and charge it, and unplug it to turn it on and put it to work.
