Super bright, easy to be spotted at night when riding a bike!

I received this product for free from Influenster and Brightz in exchange for my honest review. If I could give this product 20 stars, I most definitely would. This product is just amazing! It’s super bright. The battery lasts a long time, without exaggeration I haven’t charged it since I got the product. I did charge it before I used it though. Our favorite part is, it has different light modes. We love going bike rides and this is perfect for evening rides. It was super easy to install and we can use it with any of our bikes. We will definitely be buy more for the rest of our bikes. It’s going to come handy for 4th of July when we go on our bike ride to see the fireworks. I really, really do recommend this product and brand it won’t disappoint you at all.

Very nice!

I first want to talk about the fact that this is rechargeable, game changer! You dont have to worry about switching out batteries, which is heavenly! The light is rather bright, it was hard for me to snap a picture of it while being used because of quick movements, but trust when I say, your little or even you will not be missed when traveling in the early mornings/late nights! Mounting was a breeze, very simple to take on and off, when desired or when you need to recharge the device! Appears to be sturdy, haven't notice any signs of it wearing down as of yet. All in all, super pleased with this little light!

Reflective bike tail light

The triangle LED tail light was very easy to add on to the back of the bike. My son is looking forward to having this on his bike for when he rides his bike this summer at night. It seems well made and will hold up. The light has many options for the light sequences. It does not require much to keep it charge.

Safety first!

This simplicity of this product, is only second to how useful it is. With an easy to attach velcro feature, I’ve actually swapped it amongst our bikes, depending on who’s going for a ride. It is also easy to charge. Most importantly, it is bright and will help keep us safe on the road!

Not just for bikes

My ten year old son put this on himself, so very easy to set up. Definitely helps to improve visibility especially at night. It’s very bright for how small it is.

Not bad, could be secured better

Overall, the brightz triangle detail light wasn’t bad. It was easy to take out of the box and the packaging was great. I thought that it was nice that you could test the light out while it was still in the box as well when I did try to apply the light to my bike. I thought it was just OK. The securing mechanism didn’t seem very solid and it was only attached by Velcro. In addition the actual Velcro strap seemed a little bit too long and it didn’t feel like there was enough area for the Velcro to stick to, and so there was a long piece left off the light is really bright, and definitely easy to view from far away and so I think it would be really effective as long as it continues to stay on I might use a zip tie to ensure that everything stays in place and it doesn’t move around. That’s why I’m giving it four stars. The battery seems pretty good and I have no issues with taking it on and off to charge except it reduces its effectiveness since I’m probably going to need to use a zip tie to make it all work.

Bright and durable bike light

This Beightz LED Tail Light is super bright and has varying blinking light options. It can be mounted on the seat but my daughter wanted it on her handle bars. It is easy to attach with the Velcro strap and comes with a charger. It lasts a very long time in between charges.

Great for safety, And it’s rechargeable!!

This bike taillight is great for safety and should be on all your bikes!! It has a LED light and comes with a USB-C charging cable. The charge of last a long time, between 8-24 hours, and it comes already charged & ready to use. It easily attaches under your bike seat with a Velcro strap in a few seconds, no tools are needed! It has a very bright light and can be seen from a very far away in dark conditions with up to 10 lumens! There are 7 light modes so you can have it in a static red or yellow triangle color or you can have a mix of different flashing options. It’s weatherproof and can be used in rainy conditions. Here are the seven light modes: 1. fast flash, 2. slow flash, 3. strobe 4. high yellow, 5. high red, 6. low yellow, 7. low red. Definitely recommend!

Good Reflector

Brightz Triangle LED Tail Light is a great reflector. It has several settings, attaches easily, and does not take up too much frame space. I received this product compliments of Influenster in exchange for my honest review. Right out of the box, the reflector was ready to go: it took a minute to find the setting I wanted and to attach it to the frame. It stayed put and I'm happy to have it.

Bright cycle of lights for safety

Great addition to my little boy's bike. He just started riding his bike to school and this helps him be seen in the morning. The instructions were easy to understand. The product is easy to use right away but I had to read the instructions to see how to turn it off. Installing it on the bike was easy and simple. Since it's secured with velcro it will be easy to move from one bike to another if need be. It securely attached and stays in place. The cycle of bright lights and flashing aid in being able to be seen.

Bright eye catching reflector

The triangle reflector has several degrees of flashing and it is super bright. The patterns of flashing are eye catching. This was easy to attach to the bike seat. I will have to remember to bring it in to charge with a USB, there are no batteries

High quality

Super easy to install took me about 30 seconds. I like that it's rechargeable. The light is extremely bright and has a long range of visibility! Stays on well too.

Bright light, multiple settings. Difficult to stay up right on my bike as I must attach this on its side (cargo e bike). Broke within one month.
