Auto-Sensing Rear Light G3 -Superbright LED Bike Tail Light - Auto On/Off & Deceleration Flash by Motion Sensing - USB Rechargeable - IPX5 - Made in Taiwan

My riding times are relatively short but this seems to hold a charge sufficiently for my needs. Brightness and flash modes are good. I love how the brake light actuates based on an accelerometer sensor instead of hard wires. I recommend this.

I purchased this for my electric bike and am here to purchase another one for my daughters bike. This mounted easily to my bike with some modification. I used my own screw to mount to the bike rack (the crew it comes with is too small). I used the included stretch band to strap it to my daughters back seat.Pros:-Automatically turns on when movement is sensed in the bike and turns off on its own. Saves battery and I never forget to turn it on or off-Nice and bright-Becomes solid bright red when slowing down or stopping. I have tested this out and it consistently seems to work as intended. People often comment that they are impressed that it senses this correctly-Makes me more visible on the road-Seems to have a decent battery life, is easy to charge and charges quicklyCons:- The only con is that I wish is was bigger/longer. It is bright but tinySo far it has performed exactly as promised

I was a bit skeptical when I purchased it, but was pleasantly surprised how great these work. The light senses when it's in motion and so when it detects that it is slowing down, the brake lights turn on. When not braking, you have two options of modes: dual flashing or always on. Obviously the always on mode will lower battery life. There is a built-in battery that is not removable. To charge, there is a micro-usb port on one side that you use to charge the device. It also has an auto-off sensor which helps conserve battery levels. It detects there's been no movement for a while and the lights will shut off. Once the device moves again it will resume blinking again. The mount allows you to mount it vertically or horizontally. It comes with 2 mounting options, a rubber band to wrap around poles, and a plastic clip for clipping to your belt or some other thin object. The battery lasts for a few days, but I'm just using them for a few hours at a time. Overall, I was surprised how well the automatic part of the brake lights work, I'm very happy with this.

Es una buena luz, la duda aguín de la vararéis es interesante aunque podría ser mejor.

This light is designed to eventually fail, with no way of fixing it. After about 2 years, the battery on my light gave out, and the light won't turn on anymore. The casing is totally sealed with adhesive, so there's no way to solder in a new battery without first destroying the case.

I tell people this is my Smart Tail Light. Does everything the product description says: Turns on automatically when it senses motion, offers about 6-7 blink modes for riding, glows bright and solid when you slow and stop (making it useful for daytime riding), and shuts itself off after a minute or so of inactivity. I recharge it just once a month, but I ride an average of 4 times a week, 8 miles a ride, so others' mileage may vary. Best rear light for biking I've purchased to date.

I mounted this to the seat of my three wheeler repair bike at work but you couldn't see it because of my tool bag. So I remounted it on the storage basket and voila. Works great. Holds a charge for a long time. This high tech redneck really likes the automatic brake feature. My buddies at work always have to check it out.

The quality is not what I expected for the price. The controls are good, but not bright enough during the day. Battery last long, but uses a micro USB and is not easy to plug in. I feel like I'm going to break it every time I go to charge. Doesn't stay on the setting when turned off, so I use the static light, and have to cycle threw all the flashes every time I turn it on; my setting is at the end. The brake function seams to work well, but there are better options for less money.

Fácil de instalar y buena luminosidad

Proprio quello che cercavo per il retro della mia cargo ebike. Attaccata al cesstello posteriore grazie alla robusta molla fornita fa la sua bella figura oltreché essere utilissima perché ben visibile già dal primo pomeriggio.

Ottimo prodotto, facile da istallare e l’utilizzo è automatico!

Mi è piaciuto ola puntualità della consegna.Non mi è piaciuto ricevere il prodotto ,regolarmente imscatolato ma rotto.
