CygoliteCygolite Hypershot – 250 Lumen Bike Tail Light– 7 Night & Daytime Modes–User Adjustable Flash Speeds- Compact & Durable–IP64 Water Resistant–Secured Hard Mount–USB Rechargeable–Great for Busy Streets

Really bright and love all the different strobe settings. Charges pretty quickly and holds a charge well so far.

What I’ve received is different from what’s included. Missing 2 screws and the light holder on the Seat Stay Mount.

I wanted a bike rear lamp that was powerful enough to be seen in daylight in Northern Europe as I have to traverse a few high speed road on my bike. Even in quite bright sunlight it can be seen from about 200m on max power. What I also like about it is that unlike some competitors lamps it produces a widish beam so even if the lamp is not 100 percent perfectly aligned the beam can still be seen from behind the bikes centreline. Cygolite make an even more powerful model, but I think that would be best for daylight use only in countries that have very powerful sunlight such as southern Europe. I now have four of these, one on each of my bikes.

This light is by far the best light I’ve had for my bicycle. It’s really bright and is always seen. I have been using for about eight months now no no issues. Battery life is usually good for 150 km ride and blinking mode.

Very bright, good to fix, you.ll be seen hundreds of meters, perfect safty gadged
