Bright Bike Lights, 4000 Lumen Bicycle Light, Rechargeable Cycling Bike Light Front and Back with Taillight, Waterproof Bicycle Headlight Flashlight for Night Riding

the front light is really nice, and it is bright, the rear light is to small and not near bright enough. instead of having as many settings as it does make it brighter and safer.

I got this for my 10 year old son who likes to ride his bike to his friends' houses and around the neighborhood. We are both impressed at the brightness of the front lamp. I was going to mount it to his bike, but before I could, he attached it himself without using any instructions. I think that says everything that needs to be said about ease of installation.I like the fact that it is rechargeable via USB and not dependent on batteries that keep getting used up and thrown away. He likes the fact that he can use the lamp to charge his phone in a pinch. Great item.

The screws holding the belt clip get pulled out easily. Not a total waste. Still good for a pocket light on walks

As said in previous reviews, 400 lumens NOT 4000 as advertised. If you do any serious night Mountain biking, this light is not nearly bright enough. And then on top of the lack of light, the led indicator turned red less than an hour into my ride the very first time. The instructions pamphlet included (which is a very rough Chinese to English translation, said it was good for 10-15 hours of run time, which I knew was bs. Bottom line, not a bright light, and charge doesn’t last. Typical Chinese junk.

Very bright with the ability to select the level of brightness. The light is not as big as I thought it was going to be. However, good things sometimes come in small packages. That is the case for this little gem. Very powerful. As an added bonus you also have the option of selecting the light pattern for the red tail light. Steady on all the time of one of sever blinking patterns. Very handy to call attention to drivers approaching your bike from behind. The only thing I would have done to improve this light combo would be to have the lights connected so that you only turn on/off one switch and/or plug in one charging cable. In summary, I highly recommended this light for any bike owner.

This light is good for daytime riding for safety. I don’t ride at night, but I would think this would be ok in a pinch. If riding at night often, I would consider a more expensive brand. Riding in the daytime, using a bike light is really important. I want to be seen by cars and other riders. This light will get the job done. It has a USB-C charging port, which I like, and also a USB for charging a phone if necessary. When it comes to the smaller red rear light, this is what I consider to be more of an extra accessory than a main safety light. I would not count on this red rear light for road riding. Overall, the set is a good choice.

I doubt if this headlight is really 4000 lumens, but it puts out at least four times as much light as my little flashlight that purports to be 1000 lumens. I'm skeptical of both numbers, but either way, this light is easily bright enough to be visible from hundreds of feet and to see obstacles on or near the road. The angle can be adjusted up and down but not left and right.The rear light is not especially bright, but it can be seen from a distance and has a variety of flashing patterns to draw more attention. It remembers the chosen pattern as long as you remember to turn it off with a long-press instead of cycling through the modes.The front light clips onto a bracket that can be permanently mounted on the handlebars, so the light can quickly be unclipped to bring it inside for charging. It can also clip into a pocket to carry around as a flashlight. The rear light is held on by an elastic strap that is easy to put on and remove but feels like it will be the first part to break.

The front light is bright enough for riding in full darkness. Beam is wide enough to view the trail condition. I can see little pebbles clearly at average biking speed. 5 light modes are very handy and easy to change. I like the USB-C charging port for front light while back light still uses Micro USB port. It’s great to have built-in rechargeable batteries, which will save money in a long run. I also like the power bank function which is extra peace of mind when needed. I hope the taillight is brighter.
