turns it up a notch. With higher output, expanded visibility, smarter syncing, and deeper integration, it’s built for road
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.

Durable

So far my huge pit mix breed likes this to a lot and I’m surprised that he hasn’t been able to chew it up little bit of pb inside it and he’s focused for a good 20 minutes it almost fits on his foot too

Cute chew toy for smaller dogs!
Color: Red, Color: Red
Soooo my new puppy Dottie was continually eating my favorite pair of crocs by sneaking into my closet. To solve this issue I thought I would buy her her own chewy croc and actually found one on Amazon! lol
The chew toy is actually heavy and weighted and the material is hard enough for an effective teething toy but soft enough for the puppy to play with! My little Weeney dog loved it the second I took it out of the package! The fake croc chew toy is a very cute design with a fun, bright color. The chew toy material is constructed of durable rubber and will last a long time. I didn't like that it doesn't make noise and is small.. I believe it is better suited for smaller breads to use which was perfect for my puppies needs.

You should have one on standby.
Color: Yellow, Color: Yellow
This product was great for my teething Bully puppy, she, is an aggressive chewer. It gave her relief and kept her busy. In the 6 or 7 weeks that we've had it, it stood the test of time. She would chew 10 or 15 minutes at a time and nap from exhaustion. Overall, several hours of chewing. I must say this toy is not indestructable. In the end it was necessary to remove it and substitute another toy. The bully on the picture looks like a twin of my own pup. I did remove loose slivers and pieces that could be chewed off immediately. I am attaching a pic of the pre-disposal remnants for clarity. This is a tough toy but again, not indestructible.
