  1. Vishal Singh

    I use my bike daily for commuting to school, and have tried at least 5 different taillights. The primary reason for selecting Seemee 30Tl is because magicshine has plenty of mounting adapter option which they sell separately. So if lose or break your mounting clamp like me, you can just get the missing part.

    – Good BATTERY LIFE, smart mode gives you 10 hrs of battery life that is about 100 MILES.
    – The breathe and commit mode are amazing, definitely can CATCH THE EYE of the driver who want to mow you.
    – STURDY built quality. I haven’t tested it while biking when it’s raining, but as per the specification it is WATER RESISTANT.
    – SLEEK Design, goes well with seatpost.
    – Battery Indicator is convenient

    – A bit overpriced. (But I believe it will be more economical in a long run (if it doesn’t end up being stolen), replaceable mount, sturdy, water resistant.
    – Recharging it every week can be a bit annoying, while not as bright the AAA battery operated lights lasts 2 months for me.

    This is honestly one of the best-designed lights I’ve ever seen. Not only is it compact, the design is sleek and incredibly bright. The battery life indicator is intuitive, and the full-length rubber contact patch keeps the light from moving around. The ability to alter the tightness of the strap is super useful for when I’m bikepacking and need to attach the light to my seat stay— I currently own multiple $100+ rear lights and all of them are too bulky or not designed well enough to allow for this like the Seeme30 does. Bravo Magicshine!

    I just received this light and I have to say is ultra small very lightweight and is super bright. Can be seen in almost every angle. It is my first Magic’s one light but not my last.

  4. Pawel B

    Fantastic taillight, small and good looking but also very bright. High recommend.

  5. Paul O.

    Super bright. I really can’t say enough about the quality. It’s also pretty compact, I didn’t want a bulky rear light. 100% recommend.

  6. David Greenstreet

    I love this light! Works great riding in the day or night. Easily visible anytime of the day and also great to run with. I placed it on my rucksack in the mornings so it lights up my back while running. All around great light.

  7. Lisa

    Very bright red rear light with many different constant/blinking functions. Visible to cars and other cyclists.

  8. David Isaac Nielsen- Franco

    I like this a lot, the battery could last longer though.
