AgrieyesMagnetic Beacon Light Wireless, Class I Portable 12-24V Rotating Warning Lights, Rechargeable Amber Flashing Strobe Lights for Vehicles Trailers Trucks Tractor Bus Forklift Cars

I will start off by saying that I have put these things through heck and back. Had them on my steel front push bar in an eye wall of a hurricane and they stayed put and still look brand new. They last a long time, I've charged them like twice in the 2 months I have had them, the magnet is strong, and they are extremely bright

These lights have several flash modes which give you several warning light patterns, the magnet is strong and should work for stationary applications and they hold their charge for a long time, good value!

Sorry, I don't have a photo. I just recently went on a night run on a popular trail in my area. I only used one affixed to my chase rack and their magnet was strong enough to survive Bitter Springs Back Country Byway in Nevada. Now I feel confident about using both knowing they provide enough light for the rig behind me and that despite the terrain, they'll stay stuck on my chase rack and won't budge even a hair. In addition, the product was intuitive enough to not have to rely on documentation. Charging is intuitive, as when it is done charging, the meter light stops blinking. I also appreciate the carrying case it came with to keep the beacons protected. For the price, it's worth it, and also made me change my mind about having cargo lights installed on my Gladiator. Now that I have this awesome portable solution, I re-directed my money from the cargo light install to new ditch lights. This product was a very good buy decision for me.

I couldn't be happier with these lights. I haul a lot of equipment and these lights are great. Strong magnets,super bright and lots of great settings that really get the attention of traffic. You can see them very well at a long distance day and night. They are actually blindingly bright. The rechargeable feature is great. I use them all day and recharge overnight for the next day. On simple settings they last 12+ hours. If you use the most power sucking settings they last closer to 6-8 hours. Buy a couple of sets and swap them out for long hauls or all day use. They are worth every penny. They handle a lot of abuse,road salt,mud,gravel,getting smashed and dropped,etc,etc. very durable and long lasting.

In our line of work we needed portable/removable safety lights. These are perfect. We use these on our tractor, our mowers, sometimes on our vehicles, and even as roadside work area hazard lights. The brightness is great and can be seen very well on a bright day. The magnets are strong and survive bouncing around on our vehicles. The power supply lasts for a long time and they are easy to charge. The only reasons I have for not giving it 5 stars is that the construction feels very cheap, and they do not come with a plug in USB charger. Instead they come with a vehicle USB charger. Other than that these are perfect for what we need them for, to make our various vehicles more visible.

I use this on my Bobcat track loader for plowing. It holds tight and is very bright. Battery lasts at least 4 hrs in very cold -10 weather. I have used it 4 times now without issue. I would recommend it.

Received earlier than expected. They are solid and will perform perfectly. Very satisfied with these lights. They are bright and will be seen easily.

I've spent most of my life (I'm 64 as of this review) around vehicles with flashing lights, be it the amber lights on the family construction vehicles, or the red and white lights on the ambulances I drove for 14 years. When these folks claim that this light is SAE Class 2, they aren't kidding. It probably exceeds Class 2 by a comfortable margin. The fact it does this without a cord, just on internal batteries, is remarkable. There are some issues with the unit though. For one, and I admit mine could just be defective, the tiny indicator light near the power switch that tells you the charging status never shuts off, and eventually drains the battery even when the unit is off. I tested this on mine to see how badly it drains the battery by charging it and then leaving it unplugged for 24 hours, then seeing how long it would run. On a fresh charge, I got 5.5 hours. If I let it sit 24 hours after charging I only get 3 hours of runtime. I have a feeling that every time I'm going to want to use this I'll have to charge it first. I've also found the magnets to be fairly weak, enough so that I would not trust this at the rated 60MPH. Personally, I wouldn't trust it over 40, which is a shame. The magnets need to be much more powerful. A unit like this, rated Class 2, should be able to handle 65-70MPH typical highway speeds.Edit: It looks like I was correct in what I suspected. This unit simply will not hold a charge longer than about 6 days. After that it's so dead it takes many hours to fully charge. Mine was totally dead when I needed it at 0200 this morning and was put on a regulated 13.8vdc bench power supply for charging at that time. It is now 11 hours later and the charge indicator is still red. It is unsafe to leave batteries charging 24/7 and this is useless if you have to charge it for half a day before you can use it when you need it.Edit 2: I was contacted by the manufacturer shortly after posting my original review and they offered not only a full refund but also a free replacement unit. That unit arrived today and I've tested it and verified that it is working correctly.
