>>2053772These little shits are the best "toss it in the bag and give to an idiot roadie friend who saved 20 grams" lights out there
Not just because they are cheap, small and ubiqtous, but also because they are the perfect brightness to be visible without blinding anyone, have good strobe modes (particularly the running light mode that doesn't blink you in and out of existence, you can feasibly run it instead of solid in the dark as long as you put the guy in the middle of the pack), and don't have the idiotic fucking "brake sensing"
The battery is small, but because they aren't retina blasters they last surprisingly long, not long enough for a night ride but long enough to get you home
They are also perfect for DIY projects, they are only a big battery and a USB-C port away from being actually top tier lights, and their reflector is very easy to integrate into a 3D print
