Reflective bike tail light

[This review was collected as part of a promotion.] 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.

Not just for bikes

[This review was collected as part of a promotion.] 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

[This review was collected as part of a promotion.] 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 review was collected as part of a promotion.] 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 review was collected as part of a promotion.] 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

[This review was collected as part of a promotion.] 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

[This review was collected as part of a promotion.] 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

[This review was collected as part of a promotion.] 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

[This review was collected as part of a promotion.] 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.
