USB Rechargeable LED Road Flares Emergency Lights-Roadside Warning Car Safety Beacon Flashing Disc Flare Kit with Magnetic Base for Vehicles & Boat | 3 Beacon Disc Pack

Love this product!! Comes in a great carry case. Bright colours and lights with differing flashing patterns to make it highly visible. Battery lasts well. Has a soft and durable exterior and is magnetic.

To date, these small devices have performed exceptionally well and function as advertised. The charging process is simple and straightforward, requiring no assembly. The light quality is excellent, providing a high level of brightness that is visible from a considerable distance. Although I anticipated the magnets to be somewhat stronger, they are sufficiently effective for attachment to a vehicle or trailer when necessary. The lights are highly visible at night and reasonably effective during daylight hours. Overall, I find them satisfactory.

I've only been able to use these strobes a few times so far, but I am quite impressed. I had an 11 hour shift and the 3 strobes ran non-stop for the entire 11 hours and were still flashing bright when I clocked out. I use the magnet and attach the 3 strobes to the side of my service truck that is facing the road. I service gas dispensers 24/7 and I'm constantly dodging inpatient drivers who want to refuel and get home. I definitely noticed a difference in the driver's attitudes once I had these strobes flashing on my service truck. If you're going to be using them a lot, you'll want to make sure you avoid the strobes that take the 3 tripple A batteries. These are recharged via USB and will save you the headache of buying and swapping batteries. I love these strobes and will be buying another set soon.

Not as bright as I thought it would be ... Wonder if in fog-situation it is even visible.

Really bright, many patterns, easy to use!
