The Seemee 100 is a powerful rear safety light for road, urban and mountain bikers, with wide visibility, brake sensor and low power mode.

Transparent optical fibers allows for 100 lumens of red light to to be visible from over 1.5 miles away at an angle of 260 degrees. The Seemee 100 offers 3 brightness modes at 72, 36, 18 lumens, and 3 super bright flash patterns. Brightness/flash settings will be remembered for your next trip.

Like the Seemee 60, the Seemee 100 also come equipped with an optional brake sensor, on sudden change of speed, a constant beam of 100 lumens will be triggered offering temporarily enahnced visibility, very useful on the road or busy city streets. Though for traveling on gravel roads or mountain trails, this mode can be turned off to save power. Built in infrared sensor automaticaly dials the output to day and night mode depending on the level of ambient light detected. Low power mode has been added as well to enhance power saving, at 5% remaining power, this bike tail light goes into an economy flash mode(18lm) that will stretch remaining runtime to about 20 minutes. The runtime has been clocked at 1.5 hours to 12 hours without frequent triggering of the brake sensor.
