After riding on the road for 20 years, like many, I have invested a small fortune into my bike, wheelsets, components, carbon shoes, expensive kit, etc.
Yet this little $20 tail-light from Nightrider is one of my favorite cycling things I have ever purchased.
It works great. It is well made. It works in the rain. The mount is quality, and does not droop like some. The blinking light is VERY bright. And if the light is off, the unit still works as a reflector. Brilliant.
As it turns out, Nightrider is a really cool, independently-owned, cycling-lighting company. They engineer, assemble, and service their lights in the USA -in San Diego, CA.
Anyway... Great light. Insane value!
