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

These lights are the BEST (by a long shot) out of about 15 different kinds of light sets I’ve tried and thrown away. These look and work great! I just hope they are around for years to come because these are the bomb. Definitely 5 STARS.

I've had the previous model for 6 years and I'm very happy with how bright they are and how long the battery lasts. So I purchased these updated models, USB C connectors for bicycle safety.

best lights! can flash all red, all blue or blue & red. The blue & red flashing is very eye catching which is what one wants when riding. The better they see you the less likely to hit you. And rechargeable.

We put these on the front of our bicycles so that golf carts driving in the park could actually see us approaching. After a few near misses with ordinary lights these were a great addition and we became visible to those approaching. They would also work great on the rear, but for our purpose we put them on the handlebars facing forward.

Worked well as described. Very bright, very easy to use and well built as they’re meant to be on roads, wet or dry.

Like other reviewers stated, the red in combination with the blue is illegal here in California. Truthfully though, I'd rather be seen/noticed even at the risk of being lectured by a bored police officer. My bigger gripe is with the mount, the mount even with smooth roads will tilt the light down throughout the ride, making the light less visible. Otherwise the light itself seems to function fine.

Very bright and the alternating red/ blue lights really show up at night

I recommend this great light for bicycles at the right price and great quality
