Review on 🚔 Powerful 12-inch 36W Blue LED Police Strobe Mini Light Bar - Waterproof Magnetic Roof Top Emergency Flashing Lights for Vehicles, Cars, and Trucks by Jake Meyer

Pros: Shines brightly with multiple patterns. All lights work. The magnetic base is covered with pressed rubber. A straight chord, as opposed to those twisted chords that I don't like. Long enough to fit on the roof of my tractor and enter through the base of the rear window. Cons: The magnetic base is not very strong. I bought this for my tractor which has a fiberglass cab so the magnets are useless. I ended up trying to glue and then silicone the base to my roof. The rubber coatings on the magnets will not adhere to rubber glue, Elmers glue, silicone glue, or epoxy. Finally I removed the rubber covering the magnets and put silicone on and around the magnets and then laid it on my fiberglass roof. It worked!
