Canway Bicycle Rear Light Red/Blue, Bike Tail Light Rechargeable 168 Lumens Bike Tail Light Battery USB C 500mah 5 Modes Waterproof Safety for Road Mountain Night Riding

I've been equipping all my bikes with these lights, and they're a game-changer for safety on the road. The alternating red and blue blink pattern is incredibly effective—it really catches drivers' eyes in traffic, giving me that extra peace of mind to dodge close calls and avoid mishaps. Plus, the battery life is outstanding; I can tackle 3+ hour rides without a hitch and still have juice left for days of commuting. Highly recommend for any cyclist prioritizing visibility and reliability!

I don’t know how many of these I’ve bought over the years. I use them for bicycling on the road. I love the way you can get a red and blue flashing effect. It makes people slow down because they think there may be a police officer around. I put one on my helmet and one under my seat thank canway.

Works great

I like the blue/red color; I think the blue gets drivers attention a bit more than just red. My main issue is the battery life. If you ride longer than 2-3 hours, you should probably look elsewhere. I've had other rear lights that lasted for 4-5 long rides of >3 hrs. I tried a small battery phone charger to carry with me but decided against that since it was inconvenient to carry and connect.

Super bright and works amazingly and battery is great

The rear bike light works wonders in the dark and helps to alert drivers of your presence without being obnoxious. It easily attaches/detaches from the bike whenever you want it to. It's not so loose that it would fall off while riding. Downside is using the solid light colors only lasts for ~2hrs before needing to charge. The flashing variant lasts like ~3-4 hrs.

A must for low light cycling. Can be mounted on the bike or helmet and highly visible especially in the alternating flashing red and blue light mode. Long lasting battery life> 4 hours.

It's okay for the price. I have it mounted on my seat post. I pivot to be parallel to the ground. When I'm done cycling, it is pointing down. There's no way to lock it in position and it's very flimsy. Then, it died (it won't take charge anymore as when I connect the USB-C charger to it, it just stays lit like it is fully charged but it won't turn on anymore). More wasted money on product made in China. Not recommened!
