I'm looking at tail lights for my wife's new trike. Doing some research I came across this one. What I like is it is advertised as 120 lumens and is a USB light. Price is very reasonable. From the video's I've watched of it, it appears to be extremely bright. I was contemplating getting one of the new Lithium Iron Phosphate batteries (motorcycle type) and mounting on the trike (since they only weigh a few pounds) and that would allow use of a Whelen LIN3 like what I have mounted on my FJR. Talk about bright... but doing all that would cost over $250. Probably cheaper to get 2 of these and put on the back. That's only about $50. Anybody have any exposure to these lights and willing to give some feedback?
