The SEEMEE 150TL 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 150 lumens. It has an integrated motion sensor, which reacts immediately and makes the tail light brighter when you hit the brakes, provides additional safety. It also features an ambient light sensor. When switched to the smart mode, it will switch between daytime to nighttime modes automatically.

Operating Instructions:

Switch - A switch on the top of the housing controls all the modes and brightness.

On/Off - Press and hold the switch to turn the taillight on/off.

Motion Sensor On - When the taillight is off, press and hold the switch for 3s until the taillight lights up constantly at highest output.

Motion Sensor Off - When the taillight is off, press and hold the switch for 3s until the light keeps flashing quickly at highest output.

Every time you turn on the light, it will automatically detect whether the motion sensor is on. If the motion sensor is on, the indicator lights up blue for 3 seconds. If the motion sensor is off, the indicator will not light up.

Output Selection -

• With the taillight switched on, single press to cycle through low-high-flash-group ride-smart-low.
• In SMART mode, the taillight output cannot be manually adjusted. The light sensor scans the ambient light in real time and automatically adjusts the light output according to the environment changing.
• When the motion sensor is on, the taillight will automatically detect braking to activate the boosted 150 lumens output. And the taillight will enter to the sleep mode after 5 minutes of inaction and auto activated on any vibrations.

Memory Function - The taillight will memorize the last selected output. When turned on again, the previously used output will be recalled.

Low Power Mode - When the battery power is lower than 10%, the taillight will automatically turn to group flash and cannot be adjusted. Charge the light as soon as possible.

Power Indicator -

• When turned off, single press the switch, and the battery level indicator will turn on to display the battery levels.
• Different colours of the indicator show different power levels.
• Green: 21%-100%, Red: 11%-20%, Flashing Red: 1%-10%.
