The NiteRider Sabre 80 is a rear light with an 80 Lumen brightness. The light includes mounting hardware for attachment directly to a seat post. With a slim aerodynamic design, the light sits nicely behind most seat post without adding drag.
The Sabre 80 has six different modes, and a maximum battery life of 10.5 hours. Its battery recharges in 1.5 hours and uses a standard USB cord. An indicator on the light lets you know when the battery is running low. The daylight visible flash makes this light an essential piece of gear when out riding.
