SEEMEE 300 Bicycle Rear Light, 300 Lumens Rear Light, 5 Night and Day Modes, Smart Bike Rear Light with Brake Sensor IPX6 Waterproof USB-C Rechargeable for

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.

視認性が良くてとても気に入ってます。

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.

Gran luz trasera.

Very easy to mount onto my seat post, very bright and visible even at the lowest setting, and the mixture of static and flashing lights gives me assurance that I'll be seen at night. I usually just keep the light on the low setting with a slow flash, that's more than enough for me. Battery life is very good as well, but I only ever use it for 10 minute stretches so if you use it longer naturally it'll need charging more often. Short rides and you should be fine to not worry about it for over a month. Recommend, worth the price.

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.
