The SEEMEE 300 is an impressive and powerful taillight, tailored for road cycling, urban riding, and daily commuting. It features two light sources, a main light and an OptiTracing light. The main light utilizes two LEDs with a combined max output of 300 lumens and with different lens angles for increased visibility. Plus, the OptiTracing light can project a 360° red warning light on the road, bringing you all-around visibility and keeping you safer in road traffic.

A built-in motion sensor detects your movement and automatically increases brightness (300 lumens) when braking, so you can warn your rear reliably and stay even safer in road traffic. Also, the brake function can be turned on/off manually for extended runtime. In addition, the ambient light sensor can automatically adjust the brightness of the tail- light depending on the outside conditions, letting you focus on the road ahead.

The switch on the top makes it a breeze to access the beam settings you want. Long press to turn the taillight on/off, and click to change different modes and brightness. Powered by a massive 1600mAh battery, the taillight boasts a max 200-hour runtime, and a USB-C charging port can boost your battery for longer cycling journeys. A sleek alumi- num housing makes the taillight durable and stunning, with an IPX6 waterproof rating to protect the SEEMEE 300 from heavy rain and splashing. When it comes to mounting, you can easily attach SEEMEE 300 to the saddle or seat post in seconds without any tools.

Operating Instructions:

Switch - A switch on the top controls all 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 its highest output.

*Each time it's turned on, the taillight will automatically detect whether the motion sensor is on. If the motion sensor is on, the indicator will remain blue for 3 seconds. If the motion sensor is off, the indicator will not light up.

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

Output Selection - When the taillight is on, click the switch to cycle through LOW-HIGH-FLASH-ECO-SMART mode.

• In SMART mode, the taillight output cannot be adjusted manually. The light sensor scans the ambient light in real-time and automatically adjusts the light output according to the environment's brightness.
• When the motion sensor is on, the taillight will turn to its highest output (300 lumens) when braking. The taillight automatically enters sleep mode after 5 minutes of inactivity and can be automatically activated on any vibration.

Optitracing Light - The OptiTracing light is controlled by the light sensor. It will be off during the daytime. At nighttime, it flashes when the main light is in constant mode, and lights up constantly when the main light is flashing.

Memory Function - When the light is turned on again, it will turn to the last selected lighting mode automatically.

Low Power Mode - When the remaining battery power is 10% or less, it will automatically turn to ECO mode. The brake function is disabled during this period.

Power Indicator -

• When the light is off, click the switch to display the remaining battery level for 3 seconds.
• Different colors of the indicator show different power levels.
• Green: 21%-100%, Red: 11%-20%, Flashing Red: 1%-10%
