  • unique function of the brake light – intense lighting during a braking maneuver
  • unique Auto Standby function (auto start/stop)
  • USB-C charging   with a duration of operation of 6-16 hours per charge (depending on the selected mode)
  • low battery indicator

The radar detects vehicles approaching from behind (including scooters or other cyclists, etc.) at a distance of up to 140 meters behind the cyclist . The detection angle is up to 40°, which means good detection of vehicles even in a bend. Detects up to 8 vehicles driving behind one another. The radar communicates wirelessly with a compatible cycle computer (or sports watch), which displays approaching vehicles on the display and is accompanied by a warning and sound signal. In addition, when detected, the radar automatically increases the intensity of the integrated light, which contributes to higher visibility and safety of the cyclist.

Due to the large capacity of the rechargeable battery, the lighting duration is excellent – up to 16 hours in radar mode or 12 hours in flasher+radar mode. The modes, light output and duration are shown in the table below.  The light also has a modern and considerate slow pulse flashing mode without a strobe effect, there is also a Peloton function for group rides.

Recharging the built-in battery is ensured via the dust- and waterproof USB-C connector located on the back. The radar can be charged very easily from any USB 5V source (cell phone charger, PC, Notebook, USB network adapter , USB Car adapter , power bank , etc.) – the charging cable is included in the package. To charge, simply unclip the light from the holder and connect it to the charging cable.


Unlike the competition,  SEEMEE 508  contains unique SMART functions.

Brake light – is activated by the accelerometer. The sensor detects a braking maneuver and temporarily switches to an aggressive lighting mode with higher power.

Auto start/stop – using a motion sensor, the light automatically switches to standby mode if the bike is not in motion for 5 minutes. After driving off, the light turns on again. This function significantly saves battery.
