360° Visibility, Trusted by Pros
A glowing halo, seen from any angle.
Magicshine's signature OptiTracing light projects a 360° glowing halo onto the road for all-around visibility — a favorite among pro cyclists for its unmistakable presence in low light. Dual high-power LEDs push up to 400 lumens through the Optillumin lens, delivering a well-balanced beam with extended side reach.
Instant Boosting Alert
Reacts faster, brighter, safer.
An upgraded motion sensor detects braking and instantly triggers a full 400-lumen burst — reacting faster and brighter than ever to give traffic behind you more time to respond.
Next-Level Connectivity
Unmatched integration and control.
PelotonSync Flash automatically syncs your flash pattern with nearby compatible Magicshine taillights, so your group reads as one unified presence. FTR LightSync links to the MJ-6558 remote for front-and-rear control at the push of a button. Prefer cockpit integration? SEEMEE 400 connects directly to Garmin, Wahoo, and Hammerhead computers via ANT+ — full control right from your handlebars.
Built for Every Ride
Long runtime, all-weather ready.
A 1600mAh battery delivers up to 107 hours of runtime, with USB-C fast charging and a lockout function to prevent accidental activation in transport. IPX6 waterproofing ensures all-weather reliability, and a quarter-turn mount offers quick, secure installation on seatposts or saddle rails.
How It Works
On / Off
Press and hold the button for 1 second to turn the taillight on or off.
Mode Selection
Single click to cycle: Low → High → Night Flash → Day Flash → Eco Flash → Low...
Vibration Wake-Up & Brake Warning
Click and hold 3 seconds to toggle. When enabled, the light sleeps after 5 minutes of inactivity and wakes on vibration (fully powers off after 2 hours of no activity); braking triggers full output.
Transport Mode
While off, hold the button 3 seconds to enter or exit — indicator flashes red to confirm entry.
FTR LightSync Pairing
Hold "○" and "□" on the remote for ~5 seconds until it flashes blue, then hold near the front and tail lights until all indicators turn solid blue for 2 seconds. Once paired, both lights turn on/off together via remote.
ANT+ Pairing
On your bike computer: Menu → Sensors → Add Sensors → Taillight → Search All, then select SEEMEE 400 and add. Keep the computer and taillight within 3 meters, and 10 meters from other ANT+ sensors, while pairing. Note: ANT+ and FTR can't run simultaneously — clear the current pairing to switch.
Battery Indicator
While off, click the button to check battery level for 3 seconds: Green 100–21%, Red 20–11%, Flashing red 10–1%.
