Magicshine SEEMEE R300
Smart Radar Taillight
A Game-Changer in Cycling Safety
In an era where electric vehicles silently glide by, roughly 40% of fatal bike incidents stem from rear-end collisions. The SEEMEE R300 is a proactive safety measure — state-of-the-art radar that detects approaching vehicles up to 140 meters away, tracking speeds from 5 to 100 km/h, so you always know what's coming up behind you.

Long-Range Radar Detection
It watches your back, literally.
When vehicles approach within 70 meters, the SEEMEE R300 instantly unleashes a 300-lumen warning light, artfully dimming and slowing its flash rate as they draw nearer — ensuring high visibility while staying considerate to pedestrians and drivers alike. It's visible from up to 2.4 kilometers away, mastering the balance of safety and courtesy.
Bike Computer Integration
Traffic data on your handlebars.
Seamlessly integrates with leading cycling computers like Garmin, Wahoo, and Hammerhead, providing instant traffic updates right on your display. A dual-switch control system lets you manage taillight and radar functions independently, adapting to any riding environment.
PelotonSync Flash
Ride together, flash together.
Tailored for team adventures, PelotonSync Flash intuitively harmonizes flash patterns among nearby compatible devices — fostering camaraderie among riders while ensuring optimal visibility without overpowering fellow cyclists.
Built to Endure
Powerful, protected, and ready.
A robust 3350mAh battery delivers up to 100 hours of runtime, with Eco Flash mode extending battery life further and a clear indicator for quick status checks. A safety lock prevents accidental activation, IPX6 waterproofing ensures all-weather reliability, and a versatile quarter-turn mount fits various seat post types for a secure, tool-free installation.

How It Works
On / Off
Press and hold the power button for 1 second. Radar is active by default when the taillight is on.
Mode Selection
Click the power button to cycle: Low → High → Night Flash → Day Flash → Eco Flash → Low...
Radar Toggle
Hold the separate radar button for 1 second to turn radar on or off independently of the taillight.
Pairing With a Bike Computer
Turn on the taillight and activate radar. On your computer: Menu → Sensors → Add Sensors → Radar → Search All, select SEEMEE R300, and add. Keep the computer and taillight within 3 meters, and 10 meters from other ANT+ sensors, while pairing.
Group Ride Mode
When two or more units light up in Low mode within 10 meters of each other, they automatically switch to Group Ride mode (radar flash off, computer radar data only).
Vibration Wake-Up
While off, hold power and radar buttons together for 3 seconds to toggle. When enabled, it sleeps after 5 minutes of inactivity and wakes on vibration, powering off fully after 2 hours idle.
Memory & Lockout
Recalls the last mode on power-up. Hold the power button 3 seconds to lock; hold again 3 seconds to unlock.
Battery Indicator
While off, click the power button to check battery level for 3 seconds: Green 100–40%, Red 39–11%, Flashing red 10–0%. Level is also visible on a connected bike computer.

Frequently Asked Questions
Entry-level commuter lights typically offer limited lumen output and shorter battery life—adequate for basic visibility but insufficient for high-traffic roads, fast descents, or night rides. The Magicshine Seemee R300 belongs to the performance category, offering a 300-lumen output with radar-based vehicle detection for enhanced safety, multiple lighting modes, and enhanced rear visibility for road cycling, urban commuting, and challenging riding conditions across India.
Yes. The Magicshine Seemee R300 is designed for riders who need dependable rear visibility over extended rides. Its efficient power management, multiple brightness settings, and durable construction make it suitable for commuting, brevet events, weekend rides, bikepacking, and long-distance cycling in varying light conditions.
Yes. The Magicshine Seemee R300 features a weather-resistant design suitable for riding in rain, mist, and wet road conditions. While it is built to withstand everyday outdoor use, it should not be intentionally submerged in water.
Battery runtime depends on the selected brightness mode and riding conditions. The Magicshine Seemee R300 offers multiple power modes, allowing riders to choose between maximum brightness and radar detection range for demanding situations or extended runtime for longer rides and daily commuting.
Yes. The Magicshine Seemee R300 is designed for quick installation using a secure mounting system that fits most seatposts and saddle rails. It can be installed or removed in minutes without requiring special tools, making it suitable for road bikes, mountain bikes, gravel bikes, and commuter bicycles.
The Magicshine Seemee R300 is well suited to India's diverse riding conditions, from busy city roads to highways, hill climbs, and off-road trails. Its radar-based vehicle detection, reliable rear visibility, dependable battery performance, and durable construction help riders stay seen and alerted to approaching traffic during early morning, evening, and night rides.
The Magicshine Seemee R300 combines performance-focused lighting technology, radar detection, robust build quality, efficient battery management, and reliable visibility in a single package. It is designed for cyclists who require consistent rear visibility, advance warning of approaching vehicles, dependable performance, and a lighting solution capable of handling a wide range of riding environments.
The Magicshine Seemee R300 is available through authorized Magicshine dealers and trusted cycling retailers across India, including DoGoodCo. Purchasing from an authorized seller helps ensure you receive a genuine product backed by manufacturer warranty, authentic accessories, and after-sales support.
The Magicshine Seemee R300 uses a built-in radar sensor to detect approaching vehicles from behind, typically from a range of up to 150 metres. As a vehicle approaches, the light automatically increases its flash intensity and frequency, giving both the rider and the approaching driver added warning without requiring any manual input.
No separate display is required for basic radar-triggered brightness alerts, which work automatically out of the box. Riders who prefer real-time feedback can pair the Seemee R300 with a compatible bike computer or the Magicshine app to view approaching vehicle distance and speed, adding an extra layer of situational awareness on the road.
The radar sensor on the Seemee R300 is optimised for low power draw and is designed to run continuously without significantly reducing overall runtime. Battery life still depends on the selected brightness mode, but riders can expect dependable performance across typical ride lengths with radar detection active throughout.
