Easy installation. It just snags seat rail nicely and securely held. Screwing the light to the base takes long as you need to turn light a lot, compared to 90 degree twist type of other manufacturers. But. I like it.

The braking work when it wants to work. The light keep staying off during the ride, sometimes back on but mostly stay off till you touch it to turn it on

Good little light. Lights & Reflectors. While the brake light feature isnt 100% sensitive, it works most of the time. Good buy for the price.

Easy. Effective. Looks good. I just wish hey designed a front light for bikes that was this sleek. I don’t even notice it under my seat. And it works effectively and holds a great charge. Definitely don’t waste your time with other lights.

I installed the light a couple months ago and have been riding a few times a week since. I just leave it in auto mode and never touch it (it starts flashing when the bike moves unless it's bright outside, and it comes on brightly when the bike slows down), and the battery is still shows 3 out of 4 for charge.The flashing mode doesn't seem very bright, even considering that it's designed for use only after dark. I haven't explored the different modes to see if there's a brighter flashing…

I bought this light because my wife got one a year ago and I saw how well it worked. It flashes very brightly, the battery lasts a long time, and, best of all, when you break, it stops flashing and turns a little brighter, like the brake lights on a car.

sometimes it does not go off when is not in motion and sometimes does not go on when riding the bike.and I test it in all the settings.

Wanted a brake light for years but didn’t want to wire one . Even contemplated buying another bike that had one .So this item saved me thousands!

So much to like about this. Made of aluminum not cheap plastic, the battery life is phenomenal, the seat mounting location is easy and super secure, and the light is very bright and visible. The 4 battery level LEDs are great for helping you know when it needs another charge, but honestly the battery life is so good on this those should be very few and far between. It’s a great light that I wish I would have had long ago.

I liked it well enough, but it stopped charging after six months. I plug it in, and it doesn't register that it's plugged in. It's not the cable. It's kind of sad, really. Because I'll be continuing to use it now until it dies and then it will be gone forever.

we like that you just have to unscrew the light from the base to plug it in to charge. The brake light feature is awesome!! Very easy to take off and put back on.

Are use this on my new six seater golf cart, wish it was a lot brighter. The functionality seems to work as promised as it works as a brake light as well.

I thought this wasn't so bright at first but I played with it and found our if you hold down the power button for 3-5 SEC the brightness has 3 modes. LOW-MED-HIGH. HOPE THIS HELPS! Brake function works good as well

Responsive, Daylight visible, Wide angle, Bright brake light. Easy to install and remove. The description seems accurate. The light I'm reviewing looks like the attached pic.

This thing is awesome. It senses when you are braking and shines brighter just like a tail light should. The result is similar to what you would expect when a car or motorcycle hits their brakes. I believe this is much more noticeable and safer when riding on the street or even off-road so others can tell what you're doing. No more relying solely on hand signals.
