The SEEMEE 100 V2.0 is an intelligent tail light that offers smart integrated sensors and enough brightness for both daytime or nighttime riding. It uses transparent optical filters to spread the beam 260 degrees, the maximum output can be reached up to 100 lumens. It has an integrated motion sensor that can automatically detect braking to activate the boosted 100-lumen mode. Regardless of the current output mode, the light will switch to steady 100 lumen for 3 seconds to attract attention. Not only did we integrate a brake sensor into the SEEMEE 100 V2.0, we also added an ambient light sensor. If the sensor detects higher ambient light, the smart mode has a slower on-off flash output (better suited for daytime riding). In low-light situations, the output mode switches to a low power/high power flash setting to improve nighttime visibility. The seat post mount consists of a Garmin-type head, which the light clicks into securely. The watch-type strap is designed to tether to seat posts, tubing and helmets. And there is also a saddle rail clip for those wanting a really sleek bike-mounted option. With the convenient USB-C port, charging is very straightforward and takes 1.5 hours zero to hero. And its IPX6 rating for weatherproofing is reassuring. Features: Transparent optical fiber provides maximum 100 lumen output. 260° lighting visibility gives you all around protection. 5 modes: low, high, flash, eco, smart. Built-in motion sensor automatically turns brighter when braking (can be turned on/off manually). Ambient light sensor automatically adjusts modes according to the environment.
