BLITZU Bike Tail Light, 2 Pack USB-C Rechargeable LED Bicycle Rear Lights

Just received these yesterday. They charged fine, install easily and are as bright as I had hoped. I am using these on an e-trike to add visibility. The four lighting options work well and will help get me seen when I am riding. Too soon to comment on how long the battery lasts or how long the lights will last, but very pleased with these so far.

These BLITZU bike tail lights have been a great addition to my bike setup and overall safety. Shipping was fast, and the lights arrived in a nicely packaged box. Inside, everything was nestled in a custom foam cutout insert that kept the contents completely protected. The package included the two lights, two charging cables, a user manual, and some coupon codes. The lights are very bright, and all the light modes work great and are easy to cycle through. The rubber weather cover over the charging port seals tightly, keeping rainwater out and protecting the electronics. The stretchy rubber mounts hold securely to the seatpost with zero slipping during rides. A huge plus is the quick-release clip on the mount—you can easily slide the light out to recharge without having to remove or disrupt the mount itself. After the initial charge, the battery consistently lasts for several rides before needing a top-up. ​Overall, a well-thought-out product that offers great visibility and convenience. Highly recommended!

So far so good 👍 I think it comes charged probably 75% because it only took about 10 to 15 minutes to get a full charge. Very easy to install works great only tried it earlier tonight so my guess is though it's going to be dependable and work out just fine as other people have said it's quite easy to charge with the USB hook up so should be a fun keeper 🤗👍🍀

There isn't a need to do a huge description...I mean, they're rechargeable bike lights. They were inexpensive so my expectations weren't high. I would say, in general, I'm pleased and satisfied with the purchase. The package comes with 2 lights and 2 USB cables. Note that the cables are USB-A to USB-C and are about 5 inches long. I didn't time how long it took to fully charge, but I did see that they were full after 2.5 hours...it may have taken less than that though. I left both of the lights on in the "steady" setting (not flaishing) to see if they'd meet the stated run times. One of them lasted for about 3 hrs 50 minutes, and the other lasted for over 6 hours! I was surprised by that. I took the one that lasted longer out for a long road ride today (about 5 hours) in the flashing mode and it was still running strong when I got home. The mount that holds it to your seatpost (or whatever you choose) is pretty easy to figure out. Stretches pretty far so I was able to get it good & tight to my seatpost. Most of the photos show the light mounted horizontally but it's nice that you can choose to mount horizontal or vertical. There's also a screw that has a rubber cover (nice touch to keep it protected) so that you can adjust the angle. I can't attest to the water resistance. IPX5 means that it's not dust proof (which is fine), and should be resistant to relatively heavy water splashing. I'm not a fan of riding in the rain, so I'm not sure if I'll ever be able to test that one! ;) I have a light meter at work so I'll have to bring it to work and see if I can get a relatively acceptable measurement. It is quite bright - certainly will be very easily seen at night, but I'm also confident in it providing riding safety for daytime road rides. I will say that it's important to not pull too hard on the rubber charging port cover. I did that with the first one that I charged and the rubber cover detached (it's meant to hang from the light)...it was a huge pain to get it back in! (I don't give 5 stars unless a product is truly spectacular so 4 stars is still pretty good!)

I was hoping these lights would be bright, and they are. Otherwise, what's the point? The different light patterns enhance noticibility. They were easy to charge with the included usb-a to usb-c cables and attach easily to the bike seat post. So far, the batteries have lasted for over 3 hours without needing to be charged again.

Great deal. Works great and fits seat post nicely. Four flash settings is bright and maintains nice charge.

Love the lights. Fast charging, very bright and good for 3 hours or more. Enough for a 45 mile ride.

I've been really happy with this light. I ride 4 - 6 times per week and most of my fall and early spring rides start in the dark. I use this anywhere from 1 - 2 hours per ride (depending on if I remember to turn it off once it's light enough) and have never tested to see how many rides I can get in before it runs out. I usually charge it every other ride, just to be safe, but I assume I could get another ride or two out of it if I happen to forget to charge it. I always choose the slower blinking option. It is BRIGHT and it is easy to charge. I like the fact that it can be attached horizontally or vertically, and it's very easy to charge. The ability to tilt the light is also a plus. The only minor drawbacks I've had are 1) taking it on and off takes a little bit of precise effort and pressure on the release tab. It's a little tricky to put on or off when wearing gloves. Obviously not a big deal. 2) the rubber piece that covers the USB port tore off very easily. It is only attached by the thinnest 'thread' of rubber, so you have to be extremely careful or it will rip right off. This doesn't change the effectiveness of the light, but it might become problematic if I ever get caught in a decent rain storm. The USB port is on the back of the light, so it's protected from the rain, so I'm not too worried. ***UPDATE*** Ended up riding in a decent rain storm during a 24-hour relay, and my tail light did, in fact, short out as a result of the missing USB cover. As I was riding, I was able to reach back and turn it back on, but it would only stay on between 30 seconds and 3 minutes before it would shut off again. I had to switch lights to safely complete my night ride. I figured the light was probably toast and would need to be replaced. I put it aside for about 2 weeks but decided to give it another go before purchasing a new light. To my surprise, it worked perfectly. Turned right on and stayed on throughout the entire ride. I have since used it for an additional 15-20 rides that start in the dark and have had zero problems. If I know there is a chance my ride will include rain, I'll throw some tape over the USB port and I should be fine. I would (will) purchae this again in a heartbeat.

Ok product, battery stand-up is not good

These lights are very good and value for money. Fast delivery. Bought to put on the back of a Quantum power wheelchair. Easy to charge, they don't take long to power up. One press for a bright red light, further presses make it flash and switch off again. Stretchy rubber fastening, versatile. Really happy with them.

Haven't used these yet but have charged them up. They are bright and have a few sequences which you can choose by pressing the button. Recommend.

One piece only received.. illustration was two pieces and no updates mentioned only one piece

Excellent pair of rear bike lights. I have bought these before but these have been updated to USB C for charging. Good battery life and very bright when in use even in daylight. Easily attached to the bike seat post.
