Bike Light USB Rechargeable, High Lumen Bicycle Lights Front and Back, Bright Led Bike Headlight and Taillight with Power Bank Function, Road Cycling Safety Flashlight

I ride at night and needed new lights for my bicycle. I selected this one because of the reviews. It’s easy to install. Just took a few minutes and I had headlights and taillights. The headlight is so bright and strong that I also use it as a flashlight. My little one also uses it on his scooter. It recharges quickly, about an hour but I usually plug it in and forget about it. Not sure how long it lasts but I several rides of forty minutes to an hour before it needs to be charged. It has multiple functions, strobe, SOS, different levels of brightness but I keep it on the brightness setting. The tail light is also strong and has multiple settings. I charge it less because it never leaves my bike. By the way, I’ve had this for several years now and it’s still going.

The Gyhuego Headlight is a superbly bright, long-lasting light, remarkable affordable, and easy to use. BUT it has a very limited mounting system.I spend many hours per week on the mean streets, battling the autos for our measly little space on the side of the pavement. I depend on my lighting equipment for my very life so that automobiles will see me from far away and realize they need to accommodate the rider up ahead. Imagine my great disappointment when I tried to mount this light to my handlebar, only to learn that the mounting device is inadequate to handle the diameter of my handlebars. The only place small enough to accommodate this lights’ s inferior mounting bracket is EXACTLY the place I feel most comfortable placing my hands as I ride great disances. In other words, I can only mount the light on the part of the handlebar where I’d prefer, for safety reasons, to keep my hands.I’d recommend this light for many reasons. It’s long lasting battery is great for those hundred mile rides. It’s sturdy, it’s as bright as you need so that cars will see you. But be careful that you have a place to mount it on your handlebars where it will NOT interfere with your hand placement. For safety reasons, you‘ll have to adjust your hands, not the light, and that will make a long-haul ride much less fun for you, to say the least.

Most off-brand flashlights lie about their lumens, and 4000 was never a credible claim. But this light is impressively bright. It's significantly brighter than my 500 lumen flashlights, and almost as bright as my name-brand 1200 lumen flashlights.The bike attachment system works well. The flashlight holds well, can be adjust on either axis, and easily clicks on and off with the pocket clip.Power bank feature is excellent. After fully charging the flashlight, it took my S8 Active from 50% to 100% and later from 50% to 90%. So that's about 90% of my S8's 4000 mAh battery i.e. 3600 mAh of charging power.Red flasher light is quite bright too. It's not as bright as a $35 Planet Bike Superflash, but it's respectable and usable even in daylight.I'm probably going to buy an extra to become my EDC flashlight. It rides well in the pocket with the clip. Improvements I would recommend:* make the 18650 batteries replaceable* provide a battery level meter (ideally digital)* in 5-way mode, make the dimmest level much dimmer. It's nearly the same as the middle level.* Reverse the clip so that it can attach to the bill of a cap.I'm buying one of these for each of my college-age daughters. Great bike light, and when they clip it off for security and drop it in their purse, they now have a great flashlight, and backup phone power.

We got this light to go on my grandsons bike to ride at camp at night. This light was easy to install. It is very bright, but on the first fall that he had the mount that holds the light to the handlebar broke and now we can not attach the light back to it. I know that it is plastic, but you would hope that the plastic would be a bit more durable. other than that it it a good product. Long battery life, bright. and yes it will even charge your phone. I would not recommend it to try to fully charge an iPhone 14 as it will not charge it full. Maybe 1/2 but that's it.

It’s my second one after 4 years and the first one still works great. Good strong quality ultra bright light and I’ve compared with many others.

Fantastic, my grandson uses it on his bike. We installed it easily in about ten minutes. He enjoys the light and I enjoy the safety.

I originally bought two of these, one for me and one for my son. I was a little leary because of some of the reviews but I crossed my fingers until I got to try them myself. And let me tell you, WOW! These are incredible, are they 4000 lumen? Who really knows, but they are the brightest rechargeable lights that we own and we have several larger worklights. First off the materials these are made of are high quality metal, not some flimsy plastic that will break on the first drop (which I did, hard, it bounced and the light didn't even flicker). These have a heft to them but they're not heavy. We bike out in the middle of corn country, Indiana, and if you've never been here, Indiana has a special skill; they are ALWAYS working on the roads but the roads are never fixed. They are riddled with potholes and just mammoth sized craters. That's dangerous at night, without a bright enough light. These lights have such a beam that you can clearly see the road (or lack of) in plenty of time to react. I had a really bright light before but it was more diffused, I could see everything around me and felt like I was able to be seen but it wasn't focused enough to see the pot holes and random lumps and clumps of asphalt. This light does it all. I feel safe and comfortable riding at all hours. It's nice how easy it is to remove to charge or use as a flashlight. My husband was so impressed he ordered another one for him. I also saw complaints about the red, rear light and don't know if others got a dud, but ours were great. They are bright, easy to use and rechargeable. What more can you ask for?
