Product Features

Serious road riders put in serious miles. Most of those miles occur in the daytime, when bright ambient conditions mean you need huge lumens numbers to be seen by motorists.

But theres no reason a super-bright taillight cant look the part on the fastest road bikes. You invest in the best road bike technology--you deserve an equally fast taillight.

Packing a huge punch with 250 lumens, the Flux 250R taillight is visible at more than 1 mile (1.5 km) in the brightest daytime conditions. Here in Morgan Hill, California we get those conditions all the time—this is the taillight we made for ourselves, and for you.
