Magicshine Seemee R300 Radar Tail Light

The Seemee R300 uses ANT+ technology to communicate with compatible cycling computers or smartwatches. When a vehicle approaches from behind, your head unit will display a visual alert on the screen and provide an audible tone, allowing you to see the distance and speed of the approaching car without looking back.

The R300 uses the standard ANT+ protocol, which is compatible with most major cycling computers from brands like Garmin, Wahoo, and Hammerhead. As long as your head unit supports radar functionality, it should pair seamlessly.

PelotonSync allows multiple R300 units to synchronize their flash patterns when riding in a group. This creates a uniform, highly visible light signature that makes the entire group more noticeable to drivers, rather than having a chaotic mix of different strobe rhythms.

The unit has an IPX6 waterproof rating, which means it is designed to withstand heavy rain, road spray, and splashes. While it shouldn't be submerged in water, it is fully capable of handling harsh, wet riding conditions.

The 100-hour runtime is the maximum capacity under specific low-power settings. When using the radar and light functions simultaneously, you should expect a shorter battery life, though it is still optimized for long-distance rides and requires infrequent charging via USB-C.

Yes, the included seat post mount is designed to be robust and stable. It locks the light securely in place, ensuring it remains pointed correctly and doesn't rattle or shift, even when you are riding over potholes or gravel.
