Soondar Uprated USB Powered Rechargeable Water Resistant Cool 20 LED Bicycle Bike Cycling Wheel Light Safety Light Spoke Light Lamp Lightweight Accessory

These lights are great! I bought only one string initially to ride with for a week to determine if I liked it enough to buy one for the other wheel.It says in the product description and in many reviews, but here's one more for you:IT COMES WITH ONLY ONE STRING OF LIGHTS. ORDER TWO FOR TWO WHEELS.Other reviewers mention the nonsensical instructions but setting up was so straight forward that I didn't even attempt to read the instructions. The lights can be powered with three (3) AAA batteries, but they come with a removable, USB chargeable battery pack! Not only do you not have to worry about having an endless supply of AAA batteries, but you don't have to take the lights off or bring your bike inside to charge. Just twist the cap off, remove the battery pack and plug in. Probably my favorite part about the whole thing.Installation was a breeze. It goes perfectly around my 700c tires, with a little slack for wrapping or however you choose to do it. It comes with two smallzip-ties for mounting the power supply to the hub. I ended up buying another pack of the tiny zip ties to keep the lights from sliding down the spokes.The power button is easily accessible and, as it's the only thing on the outside of the battery pack, it's big and easy to push.I started using mine straight out of the box without charging first. So far, I've used them for about 3 hours, exclusively in the flashing mode, and I still haven't had to charge them yet. They are suuuuuper bright and certainly eye-catching.I genuinely feel significantly safer with these lights on even just one of my wheels, but I have indeed purchased a second string now for my front tire after testing them out for a week.

I'm surprisingly pleased by these lights. They were somewhat tedious to attach, and I had to use additional zip ties to keep them in place on the spokes where I wanted, but they are nice and bright, and not too heavy. Be gentle when attaching them, as I bent the wire too much and broke it. Luckily I was able to solder it back together, but most people probably would be SOL. I wish I didn't have to cycle through the blinking function each time - like when I turn it on, I wish it would just be solid first - but that's pretty minor. I haven't had them in any rain yet, and I haven't used them too long since it's summer and it's light late, so I'm not sure how long the battery will last. I like how it's a USB rechargeable though. The white is a bright, white-bluish color, the red probably not as bright.

The string for these lights is thin and I suppose could be considered "fragile" as some have mentioned, but use care when installing/attaching and you won't have any trouble at all! I've had these on my bike for a while now and have not yet even had to charge them. Granted, I don't turn them on all the time, but holding the charge for months is impressive! Also, I had my bike on my bikerack on the back of my Jeep for an 8 hour drive in a torrential downpour and they function as if they'd never seen the rain. I just ordered more today to go on the trailer I pull for my Bulldog. Buy these lights! You won't be disappointed!

I use these on my wheel chair wheels and across my rollator. I turn them on when it is dim or dark. I am much more visible, I get walked into less, I’m visible in the rain and for some reason the lights make me more approachable! It comes in one pack so be prepared to get two if using for your bike or wheelchair.

Item claims it is waterproof but there is no real seal in the battery cap and no o-ring so I don't expect these to last through season of riding. I feel like it would have been a good idea to mention in the title that this is only for one wheel, they mention it in the description but that is easily overlooked. At $24 dollars I would have bought a better set, at $12 I thought it was a deal.

They re-charge okay, but are basically just led lights strung onto the bicycle. They fall down a bit, and it's hard to keep them in place, but they'll do for safety purposes. They are hard to turn on and off, and I have to push the button a few times. That's the only really annoying part, but they work!

Love these lights. Super bright. Comes with everything you need to make you safe on your night ride. And the usb will provide you with hours of light.

Live in FL where people don't pay much attention. We ride early when there is less traffic. These lights are a nice addition for visibility. Look pretty cool too. They were a gift from one of our fur children to my husband. I'm going to get me some too.
