Bests & Worsts Reviews from Amazon

I liked the way the lights looked on my back forks and when I turned them on and thought they really popped and would be easily visible. My disappointment came after I had been riding for about 15 miles and stopped for a quick break. I took a look and noticed they weren't flashing anymore. So, I wondered to myself if I had even turned them on, so I turned them on again. When I got back home, they were off. This has been a pattern so these lights are virtually worthless to me. I do long distance rides and need to make sure I'm visible to all. I will be contacting the seller with this complaint.
