MagicShine 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 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.

Really great light, solid quality build. Easy to fit to my bike. It probably has too many modes if anything but once you find the one you like it comes on at the same mode every time. Very bright and the brake light feature is great. I would recommend this light

I really wish I had read the user reviews beforehand. It seems I’m far from the only one who’s had issues with the quality of the mounts and the lack of customer support. The light itself is excellent: bright, full of useful features, and clearly well-designed. Unfortunately, all of that is let down by a mount that’s cheap, poorly made, and simply not fit for purpose. The Trek seat mount broke after just a few rides over two months, it snapped clean off without warning. I didn’t even realise until I got to work and found the light had fallen off somewhere on the roads of London. To make matters worse, the standard mount doesn’t fit aero seat posts properly, so that’s not a backup option either. It’s incredibly frustrating. For a brand that makes mountain bike lights, you’d expect much more durable mounting hardware. Until they address this flaw and improve customer service, I’d strongly suggest looking elsewhere.

Love this rear light it’s bright, has a nice steady mode with a pulse and lights the ground around the bike as well for added visibility, its really easy to dismount from the bike to charge and last ages

The light is well constructed, sturdy and gives off a really powerful light. However, the fixing of the light into the under saddle attachment feels loose and insecure. I am regularly stopping to look at the light to check it hasn’t fallen off. Any ideas on how to make the fixing more secure.?

Fantastic rear light. Very bright and multiple options. I've cycled all my life now in my 60s this is the best I've had.

Update: the seller has been really helpful by offering a choice between a refund or replacement light. After checking alternatives light I decided that this was still the best light to get for the money and requested a replacement. Very happy with the service so I've changed my rating from 2 to 5 stars. Original review: Good product, worked as advertised for 11 months. But I took it out for one ride when the roads were considerably wet and it broke. I've tried drying it out but it still won't work. Would've been 5 stars if it was more waterproof but I wouldn't recommend with this issue.

Stopped working after 3 months, but one email to the company and they very quickly replaced it. So have changed review to 5 star

This stand alone tail light does a good job setting itself apart from those that typically get thrown in as add-ons in a set. It's very capable of putting out an amount of light that stands out and will be noticed. Not only that, but the fact that it easily integrates with popular bike computers to allow control and 'networked' behavior it's a good option for people who like to ride in groups. I fully tested it with my aging Garmin 1000. I haven't taken it on a group ride since the season is over, but I have confirmed that all the functions of the light are adjustable from the head unit. The light also turns on and off with the computer. The heavy duty construction of this tail light inspires confidence that it is built to last, and provided it ends up meeting those expectations I can highly recommend this light.

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 .

This light has some very opinionated design decisions in the software, and to the product folks out there....if you're gonna be opinionated in your design, you're gonna get opinionated reviews. Buckle up, 'cause it's gonna get a little rough. The tl;dr: Excellent hardware that forces high power consumption on you, whether you want it or not, so that instead of up to 11hrs of battery life, you get 2-3 when riding in darkness. (And yes, this is a problem - I don't want to have to charge the battery every single day.) On the plus side: USB-C charging, excellent battery capacity; good battery life* in the mode I use most frequently; many modes; mode memory; quarter-twist mount. Now for that asterisk on the "good battery life": What I want out of a bike taillight is something that flashes stupid-bright so that the doofus in the car coming up behind me looking at their phone has something catch the corner of their eye and get their attention. And this does have an excellent daytime-bright flash mode. All good so far. The problem, though, is that once it starts to get even the slightest bit dark outside, it switches to this mode where it pulse-glows out the back and shines a bright red light directly to the pavement. At no time in my life have I worried about being hit by a car coming at me from below the surface of the pavement. I get that "provide visibility from the side" thing, but guess what - you extend the lens around the side of the housing a centimetre or so and that 300lm flash (that you turned off in favour of some slowly pulsing glow) gets people's attention. "But it's too bright at night", you say? Impossible. Nothing is "too bright" for a bike to get noticed, particularly when it's red. Goal #1 through #20 is "get noticed". So, not only does the light go from a bright flashing "HERE I AM!!!" flash to a dull slowly pulsing light is that there's now TWO LED'S soaking up battery power, so the runtime of the light goes from 11hrs to maybe 3hrs at best. Yay (insert sarcasm emoji here). And if/when the battery does run low, instead of doing what it can to extend that runtime by....you know,....GOING TO THE FLASH MODE THAT LASTS FOR 11 HOURS, it instead glows even brighter so that you notice that your light is running low. Which....ok, great -- the light let you know. But what can you do about it for the remaining hour of riding until you get home...? Nothing. Just accept the fact that your light is gonna go out sooner than necessary. And then it has a brake light function: In theory, you hit the brakes on your bike, and the light shines brighter. There's no wire/sensor like there is on a car, of course, so it has to rely on some electronic sensor. So, I realize this isn't easy. But come on: If you're riding at like 35kph on flat road, peddling at 90rpm or whatever, if your speed varies between 35.8 and 35.5....the brake light should not come on. And yet it does - again just absolutely KILLING the battery life. The best part of all of these "features" is that MagicShine makes absolutely none of it configurable. If you WANT to just keep the low-power super-bright flasher going once it gets dark (and by "dark", I mean roughly half an hour before sunset on a clear day - why?!), instead of the light switching to the highest power consumption mode, well, go buy another light. Because this one won't let you. So I did. In short, this is a great light with TERRIBLE software.

Nice and bright. Better visibility than most rear lights due to the extra downlight. Like it.

Gran luz trasera.
