CANWAY Bike Tail Light, Ultra Bright Bike Light USB Rechargeable, LED Bicycle Rear Light, Waterproof Helmet Light, 5 Light Mode Headlights with Red & Blue for Cycling Safety Flashlight Light

Great light! It's really bright and the various mode are very useful. I live in CA so I can only use the red color. I can tell it really gets peoples attention because people making right turns over the bike lane actually waits behind me on a red light. :-)Battery lasts for about 4-5 hours (my ride is 1.30 hours/day). Charging is simple. I use a regular charger base (not the fast charging) because I am not sure if this unit can deal with high charge rate. I had bad luck with other things like usb headphones that just couldn't handle fast charging. The regular charging speed is about a few hours. So I usually charge it after a few rides for 2-3 hours.Mounting is easy. I ride on city streets, so I cannot tell if the thing with stay on after a very bumpy ride. The latch seems pretty solid.The unit itself doesn't feel very sturdy (light plasticky feel), so I am not sure how it will fare if I dropped it on a paved road. So I am careful when I take it out or put it back in the mount.

I have six of these. My use is on safety equipment at gas stations when I do environmental inspections. An A Frame traffic barricade does a bit to stop idiots from trying to kill me but not too much what with all these VIPs driving around in their Audis. On my A Frame I have two facing each direction. All four are flashing blue then red.I have two more of these on a lime 45" Delineator Post with a 10lb base that I bought on here. So one is flashing each direction blue and red.When I fire both of these up the idiots take notice and gaze slightly aware from the glowy things in their non-driving hand. It's partially because the humans like bright shining things (just look at all the billions made lately by having comic book characters chase glowy things around the Universe) and mostly because these lights are impossible to ignore.I'm so positively impressed with these lights that I'm gonna use two on my dirt bike flashing blue down from the rear fender.So far, I've had zero problems with these. The only problem I anticipate is the rubber strap failing. One strap is looking pretty tired.A nice feature is the light remembers what setting you last used so there's no going through all the settings every time you turn the light(s) on. Another good feature is the lights come off easily for recharging (and to prevent theft if on bicycles) for very convenient charging.Thanks to the creator of these.

Love this thing!!!! Looks amazing on my bike. I was initially dismayed at the rubber clasp was really short and looked like it would not wrap around the bike stem. Took a lot of effort to stretch it but eventually, it barely clasped at the biggest loop. Once it was clasped the light could be tilted upwards or downwards. The light is super bright!!! Love the way it looks and it's a small thin footprint.

This twilight is extremely bright and appears to be well engineered. It feels a little fragile, however time will tell how durable it will be. This light is visable from almost 180 degrees behind the bike, making it much more effective imo, than others I own. My sense is that the combination of red and blue strobe mode gets the attention of motorists really well as it is the same combination that all law enforcement uses here in California. So far, I am very pleased. Time will tell if it will be long-lived!E

Holy guacamole, Batman! These things are stupid bright. I buy stuff like this a lot because I ride in the dark to work and these are incredible. To be fair, I have only had them for a few days but I am blown away by them. One thing that the specs don’t tell you is that you can cycle through the options with the button and set it up to oscillate the strobe between blue and red, which I love. For some mystical reason, blue and red flashing lights seem to get people's attention. Especially when they are coming up behind you. They seem to be much higher quality than the other lights I have. I just hope they work for a while. I bought two but will certainly set up all my bikes with these if they turn out to be long lasting.

This is a great light to make sure you are seen. I use it on the back of my helmet in blue/red flashing mode. It attaches easily and stays in position. I personally point mine a little to the left off my helmet to flash directly at cars as they approach.Pros:1. Great battery life and quick charging. I've had it on for 4+ hours (in flash mode) and no battery life issues2. Very bright. I don't ride at night so I can't attest to using it for front visibility. However, from behind it's very bright and gets the attention of cars. Even in direct sunlight3. Button has easy access to when you stop you can turn it off without detaching it. It's bright enough that if you stop anywhere for a break you will want to turn it off so you don't drive people around you nuts.Cons:1. The included attachment strap won't fit on an aero bike seat. It's just not long enough. So my only option was the back of my helmet. I would have liked an option for a longer strap2. The included charging cable is ridiculously short. like 3" tops.Overall, I would recommend this bike light. Especially for the price

WOW!!!! This thing is incredibly bright and will command the attention of anyone nearby or far away!!!! The COB lamp beads are much brighter than standard LEDs and once consumers discover this little gem of a tail light, regular LED tail lights will be left on the shelf. HIGHLY RECOMMENDED!!!!

Order came very quick along with my other purchase. I love the brightness (since I bike at night) with the different colors. My previous bike lights weren't as bright. I like how this comes with a charger. Previous lights was just batteries. This one comes with "rechargeable" feature (usb) and saves me the batteries I would need to replace. It's a great buy if you're looking for biking lights and having the convenience of replacing the batteries. It's also important that it's easy to fit onto the bike. This one is simple an adjustable band (unlike my previous one---I had to unscrew and all). So it's easy to install and serves its purpose! recommend this product!
