    Great Light for Your Bike! This light is great! This is very bright. The battery life is pretty decent. They have different light settings. They are very easy to take on and off with the rubber attachment piece. The lights work great and provide plenty of light at night and make you very visible to the cars. This is a nice set of light for your bike that will help keep you safe and help you enjoy some great night rides!

    Great little bike lights These seem like sturdy, easy to use bicycle lights. There are well made and easy to install on the bicycle. I wish they had included a diagram of how they install on the bike, but once you figure that out it was a breeze. I love that this is rechargeable, so I don’t have to mess with batteries.

  4. Annabelle Lim

    Absolutely recommended! These light is very easier to use! Super simple to attach to my bike and once they’re on, they stay on. Would definitely recommend this to anyone looking for a reliable choice for bicycle light.

  7. Ross

    Ordered this light for my son’s bike. Install was a breeze and the look is unbeatable. Love the brake light function too. When he starts to slow, you can see the light brighten, just like in a car. Also, the install was simple and multiple different mounting types included for various applications.

  8. WOW!!!

    Wow, just wow is this a nice light. I am impressed with how bright and powerful this light is while being compact and having lots of run time.

    Overall the Magicshine Seemee 100 tail-light has been quite impressive. My favorite feature is the auto brake light, I feel that is such a huge feature. Automatically lights up as you come to a stop as well as returns to the previous mode when you begin riding again. Past that it is IPX6 waterproof, USB rechargeable with a micro USB, and has the very nice quick turn, quarter turn style mount.

    This Magicshine cycling tail light is a quality project that will most definitely protect you from careless drivers approaching from behind. It is very bright at maximum range of all its modes.

    And, speaking of modes, there is a wide range of them available here, to say nothing of the ‘braking’ function, something I’ve not seen before in a bike light.

    I look forward to using this product, writing this as I do on one of the shortest days of the year when a rear bike light is a necessary traveling companion when out on the bike.

    This is the first “smart” brake light that I’ve tried. It appears well constructed and has many different lighting modes. Finding the desired mode of operation can be a little tricky as there are a combination of short presses, long presses and double presses to get to the desired mode. It’s a little more complicated than your average tail light but then again, this is not your average light. Following the online instructions or watching the video will definitely make things easier. This light is super bright and is probably best suited for night road cycling but is bright enough to provide additional rear daytime visibility too.

    I did find the smart brake light feature a little temperamental. It will operate normally most of the time when you stop or slow down but then there were occasions when it would activate without any apparent change in motion or direction. Not sure if mine is defective but all the other functions appear to work fine. There is also a slight delay in the activation of the brake light when you put the brakes on but that would vary from about 0.5-1 second.

    The battery life appears a little shorter than most others that I have used however this is also the brightest one I have now. The USB charging is a big plus for me not having to worry about extra batteries. I usually run 2 tail lights on my bike anyway so I always have a backup for night rides. I haven’t tried any other brands of brake light yet but although this is very bright and multi-functional as a regular tail light, the braking activation still needs some development for reliable and faster functioning.

    All of the Magicshine products I have purchased are great. Came with two mounts so I can use it on both of my bikes.
    I ride quite a bit after dark and this light provides a high degree of visibility!

  12. Christopher Alvarado

    Nice light, very bright at night and can sense when you break to alert others you are stopping. Super easy to install and charge.
