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

This is a excellent taillight and brake light. Great quality. The charge lasts forever. It's also waterproof against puddles and washing your bike. The included hardware and controller are a excellent quality also. The brake light actuator is built into the light. No worries wiring. The handle bar remote installs easily. The built-in alarm is loud and annoying. The lights shut down automatically when you come to a stop. The turn signals have a loud click sound to let you know it's on. The horn is loud and adjustable to 3 different tones. After 3 months of use there's no problem whatsoever.

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.

So the alarm on this thing works great, and so does the horn it’s even louder than my motorbike horn. I’ve been told that the liquor are easy to see, and that the tail light helps at night. The only problem I have is when I put it on my rack. It doesn’t tighten well enough to stay in place so sometimes it’ll go uneven like left or right part will go a little bit to either side and it’s crooked. I I haven’t had a problem with the the battery. it lasted me two weeks and I charged it at the same time. I charged all my other things so it’s never went out on me. I can’t say I really besides that you can handle my bike going at 20 miles an hour, but I think the quality is good

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.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.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.

Rear cargo rack mount wouldn't click into the light. I looked closer and saw the plastic clip was deformed enough not to make the connection. Heat gun and a flat blade solved that problem, but I would rather have a new part.That part should have been made out of metal instead of plastic.The seat post mount works fine.The light works great. Alarm seems to work although I want to make it just a bit louder. The turn signal clicks are hard for me to hear while riding it, so I am hopeful that by increasing the sound of the alarm will also increase the other sounds from the turn signal and horn.I wrote an email to costumer service about the bike rack mount;.. let's see if they get back to me. IF not, I will be returning it and look for something a little more durableUpdat: Took stars away due to the fact that their website chat feature and email customer service is non existent.The email was kicked back as undeliverable. Chat feature was never responded to.Still no word from anyone at WsdcomI like the concept of the light, but without customer service, it's useless.Update: Someone did get back in touch with me through Amazon. Looks like they will be sending out a new part.I have updated the stars on this review for that conversation. I will post back if the new part actually works or not.
