SEEMEE 300/400 Bike Taillight,300/400 Lumen Bike Tail Light,360° Visible Smart Brake Sensor IPX6 Waterproof Rear Bike Light for Night Riding

I purchased this product and was very happy with it. Unfortunately, after three months it developed a fault. The customer service team particularly Hannah were excellent at resolving the problem and replace the item within a matter of days.Excellent resolution to the fault and really great communications throughout, many thanks, Hannah.

The Light:The SEEMEE 300 is a powerhouse for road safety. The 300-lumen output is incredibly bright, and the 360° downlight is a game-changer for side-on visibility at junctions. It feels solid and the "Smart Brake" sensor is actually responsive rather than just a gimmick.The Support Experience:I ran into an issue where my original unit (purchased June 2025) would show a full charge but refuse to power on. Contacting Magicshine support through Amazon was a bit of a back-and-forth—there was some initial confusion about charging cables and a slight delay due to the Chinese New Year holiday.However, once I provided video evidence of the fault, "Hannah" from their team was very helpful. They quickly arranged a replacement from their UK stock which arrived in just a couple of days.Verdict:Hardware issues can happen with any brand, but Magicshine actually stood by their 1-year warranty and fixed the problem. If you have an issue, just be prepared to provide a clear video of the fault and they will sort you out. Highly recommended for the visibility al

Good light, poor quality mount.***********updated post*************Order a second light and return the first one, as I got a very poor response from the seller in China. Frustratingly, the same issue happened with the poor-quality seat post mount. The mount snapped and the light fell of during a ride, never to be seen again. I would avoid this light and consider buying alternatives. I certainly wont be ordering from them again.I have been pleased with the quality and birghtness of the light. The 300 Bike twilight comes with a clever seat post mount, which gives a really secure fit. Unfortunately the quality is poor and the mount has broken on a recent ride, resulting in the light falling off my bike and suffering minor dents.Given the price point I would expect more quality from the mount and fittings, and a better service from the manufacturer. Since the light is only 5 months old and has been used infrequently during the winter season, I reached out to see if they could send me a replacement. I seem to have been fobbed off and directed to an email address in China, still no response from [email protected] update the post, if I get a response.****

I have used this for around a month for work commutes.'Menu' is interesting, I couldn't seem to get the 'motion-activated brake sensor' to stop, not a massive issue for the commutes, it has never gone flat or let me down. I’m not sure how to set it up for the 200hr setting, so can’t trust it for the 200hrs claimed, though what I do achieve is amazing!Now all MagicShine lights are USB-C you only need one cable if you're USB-C committed.For bike packing events I use this as light 1, and SeeMee 200 as my backup/spare.Having used MagicShine lights, front and rear, for the last 2 years I can highly recommend them, customer support is really good.Update - after an issue with a mount Customer Service have sent me replacement parts, I cannot fault them for the quick and simple solution. 5 stars ⭐️⭐️⭐️⭐️⭐️ 😊

Good range of modes. Very visible both day and night. Additional down facing LED teally helps visibility

I really like this bike light. Neat looking and fits well on my Brompton without impeding folding of the bike. USB charging, various light modes and good brightness. Seems well made and designed. Happy to recommend.

This is a compact, high-powered tail light. It can even be set to act as a brake light.Mounting and removal the bike is easy. Charging is through a USB-c port. Package is small, neat and tidy.This has a good range of modes - flashing/constant, low/high, and even a mode for group rides.I would buy this again.

Whilst my first light, failed after a few months, their customer support where excellent and sent me a replacement after a few initial steps. Its been an excellent light.

Superbe, c'est vraie que ça allume vraiment beaucoup notre équipe se sont tous munie de celui-ci et on regrette pas.

Gran luz trasera.

Used this for the first time a few days ago and it worked well. However after my ride yesterday in heavy fog and a bit of rain it has completely stopped working. Can't say if it was weather related or something else. It's supposed to be water resistant and certainly should be useable in wet weather. What a waste of money.

I contacted their customer service because my tail light (SEEMEE 300) had an issue. Their response was incredibly quick and helpful. Hannah, the support representative, guided me through the troubleshooting process and arranged a replacement promptly when the issue was confirmed.The new unit works perfectly, and I am very satisfied with both the product's performance and the professional support I received. Highly recommended for their reliability!

Feu arrière utilisé sur un vélotaf de jour comme de nuit. Ce feu possède une LED en partie basse qui éclaire vers le bas, laissant un halo lumineux sur la route : la visibilité du cycliste est donc parfaite ! 2 modes de fixation sont livrés avec le produit : fixation sur rail de selle ou sur tube de selle avec 1/4 tour type Garmin. La recharge complète se fait en moins d'1 heure et en mode smart night je l'utilise durant 4hrs.
