Agrieyes 2Pcs Rechargeable Flashing Lights for Vehicles, Super Magnetic Strobe Hazard Lights, Wireless Portable Amber Led Warning Beacon Emergency Light for Trucks Bus Tractor Oversize Trailer

Absolutely the best. Easily mounted with magnet on metal surface, or mounting plate that is provided. Super bright and no worries about batteries as they are easilyl rechargeable. Well worth the price for these quality lights.

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.

The media could not be loaded. These are awesome! They stayed in place while hittin potholes and bridge connections...I only used them for 4 hours and they worked all the way the whole trip. A fellow trucker told me about these and he was right! They are bright and very noticeable...

Super bright, and it lasts at least half a day.I'm always on the road going from jobsite to jobsite, and I want the advantage of an easy way to take on and off safety lights, this is it

I do deliveries in a 20 foot box truck, mostly NYC Metro area. It involves a lot of double parking and standing behind the truck in a lane of traffic. Truck's hazard lights are mounted very low and are barely visible when the lift platform is open. These lights really alert approaching traffic. The magnets seem to be holding fine even in bumpy/bouncy road conditions. I just wish there were a choice of a few flash patterns instead of the one-two rapid flash. Overall, a nice, sturdy built set of 2 lights for the price.

This is a really great product straight from the box comes charged. Just turn on choose the pattern. You wanna run and stick it on a hard metal surface. I use these one day to take my trailer full of logs and brush to the dump and they worked wonderfully. I highly recommend this item.

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.

Very nice I put them on the tractor when I drive in down the road they keep a good charge and are bright magnets stick to surface very well I do wish it came with a USB wall charger
