I installed these when I converted a horse feed bin into a delivery scooter. I've ridden over 17000 miles in the last year, and the bike has been exposed to sun, rain, and snow! The lights have done very well and I am super impressed. The delivery box pretty much obscured the original lights, so I had to do something in order to stay safe, as well as legal. Made my homebrew project look pretty pro! Draw is minimal and the lights blink and light up the way they should. Can't really ask for much more than that.
