Does the government require you to provide safety strobe beacons while you work? Do you want to be the life of an all night backwoods party, and still be able to start your truck in the morning? These permanent LED mounts will keep you working so you can pay for your portion of the party. The flashers and lenses come in different colors for different DOT applications. These are great for permanent service vehicles, snowplow trucks, towing vehicles, and many other applications.
