YOSKY Smart Bike Tail Light - Ultra Bright LED Warning Rechargeable Safety Red Taillight with Brake Sensing, Waterproof Auto On/Off Sensor - Bicycle Rear Light Review

Excellent rear light. YOSKY includes a nice seatpost mount that attaches the light with a screw. I'm using it for its intended purpose, I removed the rubber piece and attached the light to the C-pillar taillight bracket with a screw.

Works well as a tail light but not very bright. Easily detachable for charging. "Traffic light" function does not really work. Sometimes it gets brighter when decelerating, sometimes brighter when accelerating, sometimes it doesn't do anything at all. Didn't cost much so no worries about sending it back.

Bought because of the "entitlement" to automatic braking. The automatic brake light comes on even if you don't brake, for example when you're just driving down the road, the brake light is already on because it detects up and down movement. The only movement he should feel is slowing forward. I drive with this light and the brake lights are on all the time when I'm driving down the road, even if I'm not even braking. 1 star!

I really like how it works to be safe on the road when cycling. I would like a little more (about 3.5 cm in diameter), but it still lights up and there are different modes (for manual: constant, flashing and transitional, all 3 light up when "braking". And for auto: basically that's the one Energy saving mode, lights up when driving and brighter also when "braking"). Supplied with the necessary elements to install it on the bike (tube or under the seat).

Great for helping cars see me. I don't like the way the light screws into the mount as my first one fell off while driving. I don't know if it's my fault or not, but I thought everything was spinning. It also has to be unscrewed every time you charge it so you can't thread it to secure it. I use it in automatic mode so I never have to turn it on and off. I just ride and charge it once a week knowing I have a second light. The replacement light that was sent to me luckily stayed in place.

I received two broken lights, one original and one replacement. Out of the box, none of them were fully charged and efficient. Let them charge for days, even if it only takes two hours. Both continued to pulse as if charging, but never worked. Revain did a great job with a replacement and a final refund when the second one didn't work for me. This particular light, the Xlite 100, is made by many different companies, so you might be lucky if you don't try the Yosky version.

Completely dissatisfied with my purchase. My main reason for this purchase was the brake light feature. It doesn't work at all! The brake light lights up almost 100%. I bought two of these for two different bikes and they both have the same issues. I have to say the customer service is exceptional. Within an hour of raising my complaint with the seller, they asked for my address to ship two new units. I'm not sure if they will be any better, but the support team's speed and response is well…

This light (and other more or less identical lights here at Revain) has two major design flaws that I think make it unsuitable for use as a bike tail light: 1.) It's impossible to get a flash of light while riding to force . Once set to blink, it becomes constant again once the bike starts moving. A blinking taillight is much better than a permanent taillight (probably why almost all other bike taillights have a constant blinking mode). in daylight than at night. Bright light is required…
