Custer Products Lite-it Red led Light, Battery Powered, Magnetic, Heavy Duty Magnets,

A very bright safety light, would be good for trailers but bought it for my husbands bike so he had to adapt it as there wasn’t enough metal for the magnetic pads. It’s made of durable quality plastic and works well

Absolutely excellent for trailers with very strong magnets

Magnets are strong and light is big and bright

I bought these for my truck that I have only been driving during daylight hours for a 650 mile round trip with mostly driving in the dark. As it turned out most of that driving was in the rain as well. The magnets held strong and the position of the lights didn't shift at all. On of the two lights got a little wonky before the trip was finished. I think this was due to the rain. The switch on that light became really sensitive. Just a slight touch or giggle would switch it off, on, or to flash mode. I was prepared to return it but in the several days since it has dried there is no issue with it at all. So, I'm not going to bother returning it. One thing to note is that the package is for ONE light. I mistakenly thought the purchase price was for two lights. That's my fault, not Amazon's. At the time, I probably would have made a cheaper purchase. However, Now that I have these lights I'm completely satisfied.

Happy with the product but it does not shut off! I need to remove the batteries after each use for it to shut off.

works great but figuring out at first how to take the back off and get the batteries in was weird but once that is done the button works great, its got strong magnets(super strong) and it doesnt burn up the battery when not in use. i wouldnt use it in the rain though

it came with a broken back entry door , but it works ,so dont care
