GPMTER 3 Pairs Bike Brakes Pads Set, 70mm for Cruiser MTB Mountain Bicycle Universal V-Brake Blocks with Hex Nut and Shims, No Noise No Skid 3Pairs

I am disabled and purchased the lights to go on my dogs service vest when we take our evening walks. The lights attached to his vest quickly and easily with the band system, the rubber is also very durable as I stretched it really tight to insure. My dog would not shake it loose. The lights have multiple modes that all work off the one button and it is easy to toggle through them. The best feature of this seller has been their customer service. I encountered a problem with one of the two lights. I did not want to return them and wait for new ones to arrive, so I emailed the seller. I received a response back within an hour saying they would completely take care of the issue. I shop a lot on Amazon and many sellers even the ones with refund or if you don't like it guarantees never were as quick, friendly and willing to completely take care of any issue. I do not write many reviews, they and their products deserve this review. Buy these lights, their awesome!

The lights are bright. Mounts to my bike perfectly and stays in position. I went for a 8 mile and 1 mile of trail riding today. I didn't have to readjust. These are pretty bright. As one reviewer mentioned there's no manual. But he/she explained how to operate. To reiterate, I will just add few.When the lights are off, press and hold for strobe mode. In the strobe mode press twice quickly to activate the fast blinking mode. To turn off press and hold.Then a single press will turn the lights on. Press again for brighter and again for brightest. To turn off press and hold.That's it. Hope it helps.

Very nice lights for the money. They are plenty bright for daytime use. I have no concerns over battery life or build quality. A couple of notes- Don't crank down on the bands. I promise you'll brake them. Also they feel like they have good water protection but I doubt they are submersible. Also take them off your bikes before you hose them off. All in all they are a great value. I recommend you buy a few sets of them. These are my new favorite safety lights.

Tail Light is very bright, 6 modes, very impressive for the price ... White light is bright, and has the same flashing/strength modes as the tail light, but I wouldn't use it as a headlight. Light spreads everywhere, can not focus it on a road or path. But I am sure I can find some kind of use for it. And you can't beat it for the price.

I like how easy these are to mount to my bike, and they're bright enough to make you visible to drivers. But they're not bright enough to see by in the dark, so I set these to flash to make me more visible and then use a 500 lumen headlamp to see where I'm going.My only real complaint so far is that the charging port on my red light is loose, so I have to hold it just right to get it to charge. I've gotten by so far by setting a book on top of it to hold it in that position, but it's a pain. Hopefully it doesn't get worse.

After one use, both will shut off within a few minutes.After two try one will not turn back on & the other still shut off by itselfWhen working not very bright just good for dark area

Installed on electric scooter and taillight stopped working after a week. Headlight still functions and is bright enough to be seen by oncoming traffic.

The lights are very good. Their intensity is awesome. However the strap design is awful. It is hard to attach and release from the bike. In fact the strap teared apart the first time I used it while detaching it from the bike.
