Versatile Compact Lights
"I bought two packs of these for my young son to use on his bike in winter when it’s darker. They aren’t bright enough to see with when you’re away from street-lit areas but are very visible from a distance making you seen by cars and other motorists. The flash and pulse settings are particularly good at getting attention. The bike mounts are simple and reasonably sturdy but I expect the light could come out when riding on very rough terrain. Fine for streets and paths and light off road. I clip one onto my son’s hood with the built in clip which makes the light higher and more visible. Only downside is that the charging can be a bit awkward. You need to plug the whole light into a usb port like a flash drive. Okay if you’re just charging one or two but it gets awkward when you have four to charge. Would be better with a cable."
