I used this light on the back of my helmet for rear-facing safety alerts because it's lightweight. It's also lightweight when attached to a bicycle, so it's a good option for those who prioritize lightness. There are no major scratches that I can see, but it is a used item, so there may be minor scratches. Please consider this before purchasing.
