WSDCAM Smart Bike Tail Light for Cargo Rack with Turn Signals and Brake Light, Auto On/Off USB Rechargeable Wireless Remote Bike Horn Alarm Rear Bike Light Reflector Bicycle Tail Light with Rack Mount

*update after a year* It's still five stars. The battery standby is absolutely freaking ABSURD, you don't need to turn it off, it just sleeps itself and wakes up whenever you're on it. For reference, I don't ride the bike it's on all that often, but I just recharged it for the first time... after an entire year. Once I got use to it, I have to say it's an incredibly impressively well thought out little device, from having different sounds for left and right turn signals, to the very loud horn, to the amazing standby. If you have a bike that doesn't have a brake light and you ride in the city, just get this, I can't recommend it enough after seeing how durable it's been. I'm not taking any stars for the turn signal and various noises it makes being loud - gotta hear it on the bike in the city after all, but a word of warning to be mindful to take the remote off the bars (it just twists on and off very conveniently) because bumping the horn when you're trying to not wake your wife when you leave the house at 6AM is pretty heinous! The horn is surprisingly loud. Far more than any bell. It's very piercing, like a smoke alarm going off. The left and right turn signals have different sounds too, which is nice. And the immobilizer is honestly a nice feature. The delay between button press and thing happening is very present but not too bad, and it doesn't seem to really miss inputs. I do wish there was a way to just turn it off completely - maybe there is, but it isn't in the instructions. Because it's always listening for the remote, just waiting for it's chance to strike. Looks wise, it looks a little cheap. Because it is. It's a bit bulky and extends out a bit further than I'd prefer because of the horn, and the bolt on cargo rack bracket is at an angle that required me to bend my rack's mounting tab up a bit to have the light level. And the tab that holds the light into the mounting bracket is STIFF. I had to use channel locks to remove it the first time after I clicked it in, but subsequent removals have been stiff but doable. It isn't going to fall out anytime soon. (edit - I have put it through some pretty rough single track roads over roots and up/down a ton of curbs over the past year and it's never come dislodged) The remote itself is surprisingly well thought out, easy to remove, easy to cycle through light modes, doesn't get in the way. I think an angled bar mount that moved the remote further to the left or right over the brake lever bracket would be nice. And a deceleration gyro that activated the brake light wouldn't be unwelcome either. (edit - it actually has this feature, I'm not sure why I said it didn't.) But in all, it's a nice affordable addition to my commuter bike and any little gripes can easily be countered by the price. There's just a learning curve to it.

This bike tail light is phenomenal and easily one of the best cycling accessories I’ve purchased. Installation was quick and simple, and the battery life seems to last forever. The features on this thing are seriously impressive for the price. What I love most is the motion-sensing brake light and the built-in turn signals. I’ve been saying for ages that bikes should have turn signals just like cars, and when my partner sent me the link for this, I bought it immediately. It makes riding feel so much safer, especially in traffic or low-light conditions. The alarm feature is another huge bonus and adds extra peace of mind when leaving the bike parked. The light itself is bright, highly visible, and very responsive. For the price, this product delivers way more than expected. I genuinely think this is a safety must-have for all bicyclists. Highly recommend!

This thing is pretty awesome! I love having an alarm on my ebike in adition to the extremely high quality locks, but now I have one built into the rear lights. Super nice 5 in one! Not yet sure how to change the sensitivity and the instructions are ok, maybe they could be a little better though. Fairly bright lights great at night and good looking signals although they are close together on there. If it was a couple more inches wide it would perform better and people could make out which turn signal is on more easily. Battery life seems amazing! I've had it for a couple of weeks and put a lot of time on my bike during that period and used it in the daytime too and the battery is still full! Also it is very loud it's no joke if there is a wall near you it reflects back very loudly. So I have to be careful where I lock up at the stores and other places I might go and make sure the bike can't move on it's own so it doesn't set the alarm off and I'm glad the alarm only runs for 30 seconds and not constant. You have to be careful when carying the controller or fob for it so you don't press any buttons while you're not at the bike. It might detect it and disable the alarm if in range. I am always careful not to do that when I go to the store or someplace. I noticed if you press the light button it will disable the alarm and turn the lights on as normal. The turn signals and horn buttons don't interupt it though thankfully. I wish they would have make the controller or fob with a loop somwhere on the corner to use it with a keychain or something. Right out of the box this thing works great with no problems so far and I'm getting one for my wife too. Love it!

This is a really good light. I haven't had to charge it even once since the initial charging and have had it about two weeks. The remote could use improvement, it is very sensitive and the strap holding it to the handlebar isn't adequate, it always sliding and the next notch is too tight and i think it might break, I'll probably end up glueing it to the handlebar to keep it steady. The light otherwise weeks as advertised. I can't remove it from the bracket, it won't release, i feel like the bracket might break it i force it, but i can still charge it with a long usb cable when needed as the charging port is still accessible. I'm pretty happy with this purchase, just minor inconveniences.

Installed on my Walkee e-bike and better than expected. Bright, easy to charge and live the switch and sound during signaling.

This light is a really what I need to ride my bike at night. It is very bright, (so you can be seen) and it has different modes (6). I feel a lot safer when cars are approaching from behind me. I also like the directional modes (left/right) and the clicking sounds to indicate which side is active. The horn is loud (close to a car horn's which I prefer). The anti-theft alarm is also a nice feature (I have it set so that a slap/jolt can activate it). The remote that comes with this is great so that I don't have to get off my bike to see if the light is active. I have already ridden the bike through 3 rain events (heavy and light), and the light and remote still work with no problem. I takes from 4-6 hours to charge fully and the indicators/lights keep me aware. The product also comes with a mounting bracket, which can be mounted on the back rack, (which none of my previous taillights had) or on the seat post. The only negative is that when mounting the light and remote, you have to use a nut driver to hold the nut as you use the allen wrench (that is provided with the product) to keep the mount on tight. I give this product, overall five stars.

What a great taillight combo! It works great. Don't know how they did it but there's a whole bunch of useful features in this small good looking package. I no longer worry about not having a brake light or taillight. Very sensitive to braking motion. It's a set and forget device til it needs charged and I have yet to do that except for the initial charging before mounting. Not sure how to remove it when it's time to charge. The bike had a fall and light made contact with a metal bar and did come off. No damage but I know it can come off but I haven't been able to get it loose from the mount which is okay. Rather have it tight and solid than loose and lost. You'll like it.

This is a functioning rear bike light with a smart sensor for detecting braking. Has a lock and horn. Great!! What they don’t tell you is the buttons are raised outside of the shell. This makes it extremely easy to press the buttons on accident. Pair that with the fact that the biggest button on the remote is the horn makes you genuinely lose your sanity every night when something as little as nudges the button and it screeches like a car horn. The holder that attaches to the bike is also not at all stable. My bike lights were constantly pointing downwards. Additionally, after about a week, I went to lock it up after riding to the gas station & noticed that the light fell off the bike. The attachment is not stable or secure and it will fall off. The silicone strap for the handlebars are also not secure and will 100% fall off (I resorted to attaching it to my keychain)

This is AWESOME!!!!! Installation a little more complicated as it’s for my dirt bike however the security alarm feature is so cool, once you arm it, if anyone touches it - the alarm goes off - excited to ride with these lights now installed! Highly Reccomend - I’ve tried and tested a few of these and returned due to incompatibility but this unit is PERFECT - HIGHLY HIGHLY Reccomend !!!!

This is my second purchase of this product, because the battery faulted out after 8 months!

This is a good addition to your bicycle and ensures a safer ride. The light is bright including in day light. The indicators are a good idea . The horn is adequately loud too. Altogether, all though rather pricey it is worth it.

Donde se atornilla para sujetar la bicicleta como esta en la foto es muy fragil ya que es de plastico si pasas un bache o algo por accidente se rompe deveria de ser de metal las bases para fijar.

El claxon y alarma suenan muy fuerte, lástima que no lo he podido usar en la calle porque el control es para un tubo muy delgado y no le quedó a ningun manubrio de mis bicis. Solo me ha servido para sacarme unos buenos sustos al presionar los botones por presionarlo por error dentro de la caja de mis accesorios. Jajaja. También da un poco de flojera que se tiene que tornillar, no es tan práctico. Pero aluza bien.
