cyclists and urban riders who expect more from their taillight.
360° Visibility, Trusted by Pros
Both SEEMEE 300 and SEEMEE 400 feature Magicshine’s signature OptiTracing light, projecting a 360° glowing halo
onto the road for all-around visibility—a favorite among pro cyclists for its unmistakable presence in low light
condition. The Optillumin lens remains the same across both models, offering powerful rear and side illumination
through a compact, clean design.
Instant Boosting Alert
Both SEEMEE 300 and 400 feature brake detection—but SEEMEE 400 pushes it further with an instant 400-lumen
burst triggered by an upgraded motion sensor. It reacts faster and brighter, giving traffic behind more time to
respond and enhancing safety at every brake.
Next-Level Connectivity and Control
As Magicshine’s flagship taillight, SEEMEE 400 brings unmatched integration and coordination to your ride.
PelotonSync Flash lets multiple lights flash in unison—automatically syncing with nearby compatible Magicshine
taillights. Your group appears as a unified presence, boosting visibility and cohesion on the road.
FTR LightSync Control links seamlessly to the MJ-6558 remote for front-rear control at the push of a button. Prefer
cockpit integration? The SEEMEE 400 connects directly with Garmin, Wahoo, and Hammerhead bike computers via
ANT+—giving you effortless control right from your handlebars.
Built for Every Ride
SEEMEE 400 delivers up to 107 hours of runtime, USB-C fast charging, and a lockout function to prevent accidental
activation. Its IPX6 waterproof rating ensures all-weather reliability, while the quarter-turn mount offers quick, secure
installation on seatposts or saddle rails.
SEEMEE 400 is not just a brighter version of SEEMEE 300—it’s a smarter, safer, and more connected evolution. For
riders who go farther and ride smarter, it’s the taillight that keeps pace.

Very good
I really liked this teeth whitening kit. It comes very complete with an LED light, whitening gel pens, and a shade guide to track your progress. The instructions are easy to follow, and the design is practical and comfortable to use. After several uses, I noticed my teeth looked a bit brighter and cleaner. I also like that the device is rechargeable, which makes it convenient and easy to use anywhere. Overall, it’s a great option for at-home teeth whitening.

Must have!
I am honestly blown away by the Puur Smile Teeth Whitening Kit — it’s become a must-have in my self-care routine! From the moment I started using it, I noticed a visible difference in the brightness of my teeth. Even stubborn stains from coffee and wine have faded noticeably after just a few sessions.
The kit is super easy to use, and the instructions are clear and straightforward — no fuss, no mess. I love that it doesn’t cause sensitivity like other whitening products I’ve tried in the past. The LED light feels gentle, and the gel goes on smoothly without irritation.
My smile looks brighter, cleaner, and more confident — and I’ve already gotten compliments from friends and coworkers! The results feel professional quality but at a fraction of the cost.
If you’re looking for a reliable, effective, and gentle whitening system, this kit is a total winner. Highly recommend! 😁✨

Ready, Set, Smile
So far I’m impressed! I’m anxious to see the results after more time. It’s easy to use and it seems much more professional than others I’ve tried.

Haven't seen an extreme difference
This looks to work about as good as any other teeth whitening product out there. It has the whole mouth piece with the light, i can't say is actually doing anything special. The real magic seems to be whatever is in the tubes, but the stuff only works about as well as any other whitening strip i've ever used. You'll get a few shades whiter, but nothing absolutely crazy. I think for the trouble of applying and then wearing the mouth piece to throw the light on to get the whole thing going, i'd rather just use burst white strips or something similar.
