Bike Tail Light-USB Rechargeable Rear Bike Light, 7 Colors LED Flash Light for Road Bike, 60 Hours Runtime, IPX5 Waterproof Easy to Install Bicycle Light

It’s the bike tail light I ever bought. The rear bike light has a higher visibility whether you use a steady mode, slow flash, red/blue flash and 7 color led flash light. The 7 color cycle flashing pattern is wonderful, very beautifully and cool.The bicycle rear light worked amazingly for one day and night and will not take a charge even after 40hrs. the USB rechargeable battery seems to last forever! Incredible battery life !!Easy to install and remove, USB recharge, power indicator , waterproof…. Good enough rear bicycle light.

This light is bright, well-constructed, and offers two brackets for easy, mounting to seat rails or post. A thumb screw secures the light to avoid falling off if you hit a bump. It offers excellent battery life throughout all four light modes: 1) Flashing Red; 2) Solid Red; 3) Alternating Red and Blue and; 4) Alternating Colors. All enhance visibility very well. The light and all parts, feel solid, and well made. I mounted it to my seat post, since under seat mount wouldn't fit my seat rails. Overall, I recommend this product, highly.

Light brightness is very good although it could use a couple more patterns for the red light.The original light i received had the old style mount that clamped on the seat rails with a 2 piece bracket and a long screw. It broke while installing. The seat post mount worked fine, but the thumb screw was too short to hold the light on for bumpy trails. I sent an email to Padonpower and they responded quickly and said they updated the mounting system and to do a replacement through Amazon. The updated seat rail mount uses 2 zip ties (4 included) which is much easier and stronger than the original mount. The seat post mount appears to be the same except the included thumb screw is slightly longer and now works to secure the light in place.So the updated mount and light are 5 stars, Customer service at 5 stars, but I would rate the old style mounts at 1 star...

Very nice lights which get you noticed on the road. The bolt for the under the seat mount was missing, but I got one from my local machine shop. The bolt for the seat post mount was included but I preferred the positioning of the light right below the seat. I already had another seat post light and I wanted to use one light in "solid" and the other in blinking mode, to improve the distance judgement by oncoming drivers. I will use a portable battery to charge the new light, so that I do not need to worry about forcing the light off the mount, thereby increasing the risk of breaking the plastic mount.

Not bright during the day time and not bright on the peripheral. You need to see it head on.

I really like the lighting patterns of this light. No sure about blue-red flashing, as it might be not legal. The rotating between 7 colors is the best, this will get you noticed on the road for sure.But, the mount is junk. I could not make it work for both mounts. I could not push the light into its mounts, afraid I will break it. If it just have have a decent mount..I would pay 10 bucks more for it, if it has a good bike mount. Light is cool, be there is no way to mount it so it is next to useless.

Light could be brighter, but what I did like was that it mounts to the saddle rails. Me aero seatpost would no accommodate several lights I tried. Battery life is very good. Light works for me.Lowering one star until resolved.2nd Review: after 3 rides, I lost the mounting nut and bolt. After properly tightening bolt to seat rails, never realize that the rails can flex when riding. Enough that the nut works its way free and bolt soon after.Will request a replacement if possible. Light is now held in place with a plastic tie wrap trough mounting bolt hole.3rd Review: Was sent new mounting bolt and mounts, nice customer service.4th Review: USB charging port loose, need to continuously pull charging cord to one side to charge, otherwise will not charge.

The light is very cool and super light weight. Beautiful bright colors! The mounting hardware not so great.
