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

It works as intended but for the price feels very cheap and plasticsy. Thought it would be much sturdier.

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.

Llevaba tiempo queriendo comprarlos, llegaron 1 día antes de lo acordado, y funcionan bastante bien.

I have earlier versions of these that use AA batteries. They work well. The idea of adding a rechargeable battery makes sense. I have had the AA battery units in my cars for years and then tested them and found the batteries were fine. But, it is possible they would have died after years in the trunk. The rechargeable battery could be recharged from the car battery using a cell phone charger (standard USB included). Even with a low battery that won't start a car, there's enough "juice" to run a cell phone or charge these. I think the rechargeable concept is a good idea. Otherwise, these work as well as the previous models. In practical use, these things are bright! I have driven along the road and there was a car on the side of the road with at least 3 of these running that circular pattern. You would have to be blind not to see this from quite a distance. These are so much better and safer than the open-flame traditional road flares. And, these last far longer than the traditional road flare. Being magnetic and with a built-in plastic hook/hanger in the back, there are options for getting them up higher such as on your roof or on the back of your RV or trailer, for example. For the cost of these things, I think it's a no-brainer to get them. And, the little case to hold them makes a difference. It's just easier, so go for that, too. Short story: One time my alternator died and the battery ran down. The car died. I was stuck on a highway at night in a pelting rainstorm in a dark red car. My 3-way flashers would not even work. I figured at any moment, I would get rear-ended because there was almost no shoulder. It was one of the only times I ever called 911. They came out and set up some flares until the tow truck arrived. Thankfully. After that, I started carrying flares. That was years and years ago. Since then, these LED units were invented and I switched to those. I have sets of 3 for each of my cars. Well worth the piece of mind, IMHO.

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.
