Review: Good light with decent battery life. - Good strong light. I wish the strobe setting blinked faster. I bought it for the battery life and so far (3 mo) it has held up to the time advertised. I ride in the country on back roads and this makes me very visible from behind. Wish it had a clip attachment for my saddle bag - I had to Jerry rig it. But I works .
Review: Outstanding customer service and hassle-free replacement - I purchased the SEEMEE 300 in July 2025 and was very pleased with its design, brightness, and overall performance. After several months of light use, the unit unfortunately stopped working after a ride in steady rain. I reached out to Magicshine support through desertcart, not really knowing what to expect. The customer service experience was excellent from start to finish. Hannah from Magicshine responded promptly, asked clear and reasonable troubleshooting questions, and carefully reviewed the videos I sent showing that the light would no longer charge or turn on. Communication was polite, professional, and patient throughout, even when an earlier email didn’t go through and needed to be resent. Once it was clear that the unit had failed, Magicshine immediately arranged a replacement without any back-and-forth or pushback. The replacement arrived quickly (one day earlier than the original estimated delivery date), and the process was completely hassle-free. It’s rare these days to see such responsive and fair after-sales support. Magicshine clearly stands behind their products, and that gives me a lot of confidence as a customer. Based on both the quality of the light and the outstanding customer service, I would absolutely recommend the SEEMEE 300 and Magicshine as a company.

## Questions & Answers

**Q: smart day/night function does not seem to work. How can I enable this mode?**
A: I have found that light automatically switches between smart day or night. I own both the seemee 200 and 300 and I ride early morning before sunrise until after sunrise. When I select the brake mode by long pressing the power button until the light illuminates solid and then I select the mode I want; the light will automatically turn off the optitracing light after sunrise and be in day mode. The optitracing light only illuminates in night mode.

**Q: Can the mount fit my aero seatpost?**
A: Yes sir.  Also a seat mount is available if you have a bontrager seat or a new specialized.  They have screw holes underneath for the special $10 mount

**Q: Will this attach to a road bicycle race Helmet?  Pulsing effect looks great to help drivers accurately judge position of cyclist**
A: The SEEMEE 300 is not designed to be attached directly to a road bicycle race helmet. It is primarily meant to be used on all standard saddles or seat posts.

**Q: Magicshine, I know you have an updated Allty 1500S coming out next month, is there any upgraded taillights (SeeMee) being released soon as well?**
A: The SEEMEE 300 is now our newest taillight!

### ⭐⭐⭐⭐⭐ Built tough, bright as heck!
*by P***. on December 4, 2025*

Got the 400 because it connects to the remote that I have that came with the Hori 1300. Syncs perfectly with my lights now and my goodness it is bright. Be careful when it's on High Flash mode. Momentarily blinded when I was testing. Battery lasts longer than anything I have owned even on non-eco mode. Speaking of which, eco mode is only when you really need to save on battery. Very low visibility on that mode. Rather have it on flash than eco mode. Got the Black Friday discount so I got it at a fair deal. LOVE the pulsating, dowfacing 360 degree light!
