Introducing the latest in ‘Smart Flares’ – The Ice Cream Sandwich Road Flare ! These sequential flares not only warns drivers of activity ahead but also direct traffic direction. The sequencing technology helps to keep workers and users safe by guiding traffic away from areas where personnel are on the road working. The square shape design keeps them from rolling into traffic. The lit LEDs automatically adjust to horizontal or vertical orientation (when magnetically attached to your tailgate) so the flare ‘knows’ which lights to turn on. These road flares are super durable. They can be driven over, dropped, thrown and they will not break. Great low price – LOWER than many NON-sequencing flares and they come with a 1 year manufacturer’s warranty. No Tools needed to change batteries. They use 4 AA-Alkaline and provide more operating time than any of the competition.
