Rear Bike Light 80 Lumens – Rechargeable USB-C, Waterproof IP64, Lightweight 0.11lb, 5 Modes Steady/Flash with Memory Function, DON PEREGRINO M1 Bicycle Tail Light

This bike light is a very good value for what it is. I like it for several reasons. It's easy to install with a simple elastic ring. It can be positioned anywhere on the bike frame. It's waterproof. It's really bright, definitely helps with visibility and safety. It's rechargeable, so I don't have to worry about batteries going bad and ruining it. I do have to remember to switch it on and off, but that's not a big deal. I feel like the quality is good, especially for the price. Worth investing a few dollars in safety for yourself or your kids.

I often ride with a bag sitting on my rear cargo rack, which means that lights attached to the seat or seat post are blocked. I got this one because it's designed to be attached to the seatstay (the pole connecting the seat post to the rear wheel). That's well below the bag and rack, so this light isn't blocked.One thing to be aware of is that when attached to the seatstay, there's a certain angle from the other side of the bike where the tire will block the view of the light. You'll want to attach to the left side, since that's where most cars coming from behind you will be (at least in the USA) as you pedal on the right edge of the road.The light is pretty bright, certainly bright enough for night riding. It might be less visible on a bright sunny day. Testing it on steady mode (solid on), I got 2 hours 45 minutes, not quite the advertised 3 hours but close.It's pretty easy to attach the light to the bike. A single rubber band, provided, stretched from clips on one side of the light to clips on the other, snuggly fitting the seatstay.I guess the one thing I don't like is that you have to fully remove the light to charge it. Most other tail lights, you can slide or twist the light to remove it from the bracket. Here, there is no separate bracket except the rubber that's part of the light. That's not too big a deal, since the light detaches from the bike easily, but I can see myself dropping or misplacing the rubber band while recharging.

This is a fairly large rear light. It charged on my USB-C and took a reasonable amount of time to charge which leads me to believe the battery is a good size. I don't see the size of it on the ad page or manual. The light is bright and is not too heavy. I like that the rubber groove fits onto the seatstay of my Emonda and Domane. I prefer lights on the seatstay because I use a seat bag. This is a very good light especially given the $14 price tag. Quite happy with this order.

This is similar to other rear bike lights I have used. I ordered this to replace one that was lost.The instructions are minimal and not the easiest to understand but I have gotten used to that. It is not that complicated to use.It charged in a reasonable amount time using one of my USB charging blocks.It mounts with included rubber straps similar to other lights I have used. It is easily removable and you need to remove it to charge it.It is fairly bright. It's not as bright as our brightest light but I have used worse. Overall a decent light for the price.

I got this for one of my kids so they could ride later into the day without sacrificing too much safety. It works well!

This bike light is good sized and mounts easily with an adjustable rubber strap. Its plenty bright enough with five flash modes. I like that its rechargeable so it wont eat batteries. I mounted this on the rear basket of my e-trike and it is working fine.

This bike tail light attaches securely around the seatpost of my bike with a thick rubber band. It feels very secure there and faces rearward at good angle for visibility, but I'm a bit concerned about how long the single rubber band will last, especially since it will need to be removed each time to charge the unit. The tail light is larger and heavier than my other tail light which simply clipped on the back of my under-saddle pouch (it weighs 1.8 oz), so I expected it to be brighter. But it appears to my eyes to be less bright, and when I did some checks with a lux meter app on my phone, it showed that the old tail light was significantly brighter. This might be sufficient for riding at night, but I was hoping for a really bright tail light that would be more noticeable from a distance on a sunny day.

This style of tail light, that runs vertically up the seatpost, is my preferred type. They are quick and easy to fit to most bikes, quick to take off to put them on the charger when they run low, and they are narrow enough that they don't bump your legs when pedaling, or get knocked out of place easily.This particular one is bright, offers several flash patterns to suit your needs, and has an easy access port to recharge. I have not had the opportunity to test its waterproofness yet though.My 2 cautions are: 1. The angle of this light relative to the attachment point is fixed, whereas many others have a pivot integrated into them. If you have a bike with standard angles, where the seat tube slopes back at about 73 degrees, then this should be fine, but for bikes with a straight up seat tube, as on some triathalon bikes, or bikes with a very laid back seat tube, as on some full suspension mountain bikes, then the visibility may be compromised.2. The light only comes with 1 of the silicone "rubber bands" to secure it to the seat tube. For my regular around town bike, which has a 27.2mm seat post (which is by far the most common size) it worked fine, but the band was pretty much stretched to its limits. If you have a bike with a larger diameter seat post (like the 30.9mm or 31.6mm that are common on a lot of higher end bikes) it may not fit unless you find a bigger band to use.

Very easy to install, i don't know why i put it off for so long.The light has a reliable shine to it, something you can trust.Charging is very easy, especially with a powerbank.Battery life seems vast.The waterproof rating isn't good enough to be submerged so don't let that happen, rain and splashes is fine.The price is great, for a more robust backlight you'd be paying at least twice as much.This one is fine unless your bike is a rock star.

Très bien pour supplémenter le feu arrière de mon vélo déjà existant, et augmenter la visibilité de nuit. La recharge par USB-C est pratique.

ottima visibilità e facilità di installazione

Simple à installer grâce à une boucle fournie.La recharge se fait en USB-C.La luminosité est bonne, sans être excessive.

Well made Rear Bike Light with several modes of illumination. I like the fade in/out setting, a bit different from others I've owned or seen.It fit's onto your Seat Tube by the popular Silicone Ring method. Popular because it's cheap to produce and easy to get on, problem with it is that it's easy to remove as well...even easier for a thief in a hurry.From that comment you can see I'm not a fan of anything that attaches to my e-Bike with an Elastic Band !Another thing to watch out for albeit rather obvious, that is a Bike Light naturally needs an unobscured view of the Road behind to do it's stuff. If you happen to have a Saddle Bag, Rear Rack Mounted Bag or Large Seat Bag attached to your machine it will make fitting a Light such as this impossible.A light like this is more suited to a ' Mountain ' or ' Racing ' Bike rather than a machine you ride around town with your shopping on a Rear Rack.All that said it's a very nice Rear Light indeed and I'll certainly be using it during those times when I have nothing on my Carry Rack and it can been seen by those behind.
