Magnetic Wireless Strobe Light Red Warning Beacon Light for Trucks

This light is nice and bright. 4500 Lumens. It is perfect for what I wanted. The magnets are strong but I'm not sure you could drive around with it on your car without it blowing off. It did not come with any instructions. It would be nice to know how long to charge it. Otherwise it is a good flashing light.

This light works well and is surprisingly bright. No need to run cords for use. Contained rechargeable battery allows use anywhere there is a metal surface for magnets to stick to. Only drawback is it only had 2 settings steady & flash.

I use these at festivals. The magnets are strong. The only reason for a 4 is you can only charge in a truck.

Top drawer emergency light. Should be in everyone's vehicle. Be prepared.

I work on marine terminals and need as much safety as possible. I have two of these. One orange & one red. I put them on my car while driving around the terminal. The magnetic suction is good as well. I drove home with it still on. I had forgotten to take it off before I left. It never moved at all when I noticed it after I got home. I'm on terminal for hours at a time & have never experienced it dying.

Bright and gets the point across but for how often use this I forget to charge it. The magnet makes it easy to put on but isn’t the strongest for when in a hurry to a scene.

Mounted on top of golf cart roof very bright and super safe when driving

Very cheaply made and very toy-like. I probably wouldn't buy this again for actual use in a vehicle. But it was good for a cheap Christmas present to take to a gift exchange.

Not as bright as I thought it should be. The LEDs emit a yellow/orange light as opposed to a brilliant white light which makes it appear dull I think. Left it flashing for many hours in the cold and kept working though.
