Bike Tail Light with Turn Signals, USB Rechargeable 4 Pcs Bike Turn Signals Front and Back, Wireless Remote Control Bicycle Turn Signals for Bicycles, Electric Bikes, Scooters, Motorcycles

Overall this is an AMAZING product. First the good... It was easy to install and the lights are easy to remove for charging. They provide a harness to charge all the lights at once. Everything works flawlessly and the lights are surprisingly bright. This is not a cheap product at all. Everything is solid and works as advertised except mine doesn't beep when flashing as shown in the video. I'm fine with that. The blinkers turn off after 30 seconds but can also be canceled sooner if you don't need them for that long. They look nice and just work. HOWEVER, there is one BIG caveat. There is no way to turn them off. The Bluetooth receivers are always active. They must be recharged at least "every 2 months" when not in use or the batteries will run down. It doesn't mention if there is a low-voltage cut-off or not. If not, running the batteries out will permanently ruin them. Did they sit on a shelf for 2 months before shipping? This is no big deal if you are a regular cyclist. But if not (or in the WINTER) this could be an issue. Other very minor complaints are that the waterproof covers over the charge ports are questionable and the backlights on the controller, when in use, are very dim.

My e bike didn’t come with any turn signals so off to Amazon I went! Very glad I went with this product it comes with both front and rear turn signals. SUPER easy to install and I didn’t have to connect anything to the battery which made it a breeze! They’re bright enough to work in the day but they really shine at night (obviously). Package comes with 4 micro-usb charging cables that all connect to one USB plug in. You will need a second micro-usb for the button controller if you want to charge all 5 items at once though. I love that when I press any button it beeps, being a quiet e bike, this really helps if I forget to turn it off. The button controller also lights up when you press it, though it’s almost impossible to see in the day light. There are also 2 modes that look like they would be emergency lights. In the video you’ll notice I didn’t have a place to mount the back two lights but I made it work. It does come with an attachment/mount should you have a traditional bike seat. Just received the product so not sure how the battery life is just yet. Also, if you’re in the elements a lot you might want to get replacement rubber rings that you use to attach everything.

Used this on my recumbent bike. It was super easy to install, just make sure you put the lights on the correct side (I now have labels "R" and "L" on them). They fit on even smaller posts. The beep is (annoyingly) loud, but it for sure will remind you to turn it off! Mounting is pretty tight because of the bands used. I should have no problems using this on longer rides.I read about people complaining you need to take them off to charge. Well, you need to do that for any bicycle light. Yes, there are 4 separate lights, but the charging cable supplied has 4 connectors. Personally I don't see that as an issue. I don't know how long the batteries last, haven't used it long enough to wear them out.

I had problems pairing them but I gave support a call and they fixed me right up. They work beautifully. They are very bright but very pricey but still the best bicycle turn signals on the market.

This product was great, until I lost my rear left turn signal one day. I searched the route that I took before I realized my signal was missing and I was unable to find it, so likely a car ran over it and kicked it into the abyss. Unfortunately, when one light for a side goes missing, it does not work at all on the specified side. I contacted the seller to attempt to purchase a new light, but they did not want to sell me an individual light, leaving me the two options: Spend another $64 and hold onto the old lights as paperweights or risk getting hit when hand signaling in the dark.

These signal lights are amazing and effective, especially at dawn and at dusk. Highly recommended.

Product seems well designed and works great, BUT: it appears to use Bluetooth Low Energy for communication, and by low energy they mean LOW. If I install the rear signals on my rear basket struts where I want them, they are too far away from the transmitter and only respond to one out of ten button presses. I had to move them up closer to my seat where they aren't as secure (my bike's design precludes using the seat tube mount) in order to bring them in range of the transmitter.UPDATE: Dropped to two stars, returning. After moving the signals closer to the transmitter (less than 3 feet away!) they still only activate 4 out of 5 times I press the button. Not acceptable for a safety critical device! Would you drive a car where there's a 20% chance the turn signal won't come on?
