Includes hardware to boot on if desired. I have a team of disaster recovery workers and we’re adding these to all of our vehicles for safety when moving to and parked at work sites. Very low battery draw. ### ⭐⭐⭐⭐⭐ Reliable *by D***N on September 11, 2025* It works for me ### ⭐⭐⭐⭐ As Described *by J***E on September 5, 2024* After looking around for some sort of warning light to be used on a piece of equipment when it is being used adjacent to a highway, this rather versatile beacon appeared on the radar. So, it was ordered. The beacon arrived in short order -- 2 days. And, was in good condition. It measures 3-7/8" in diameter and 4" tall. The illuminated portion is 2-1/4" high. The cord is around 8' long and has the normal cigarette lighter power plug which includes ON/OFF and Flash Mode buttons. Yes, this light is blue. And, that is a color normally reserved for law enforcement. Which is why it was chosen: Drivers see blue lights, they automatically slow down and behave a bit more sanely. Resulting in a safer operation. I like the 12/24-volt power supply options because it can be powered by a power tool battery in situations where a lighter plug isn't available. Its effectiveness remains to be seen. One observer says it is bright. Maybe I was expecting too much because I wanted extra-bright! Time will tell. ## Frequently Bought Together - Justech 12/24V Flashing Beacon 40W 40 LED Emergency Warning Strobe Light Amber Strobe Lights 7 Flash Modes Waterproof with Magnetic Base for Truck Vehicle - Caledonia Signs 56336 Vehicle Hazard Panel, Reflective Magnetic, 700 mm X 140 mm - Highway Maintenance Chevrons - Retro Reflective Yellow - Magnetic or Sticker Signs - Car Van Tipper Tail Lift Ect.
