## Description

Product description

Review: High quality, low price. - I got this light for my e-bike, and it has surpassed my expectations. To start, I did not charge it out of the box, I just installed it and ran with it. The light lasted from Monday until Thursday for 40 minutes per day. Not bad for right out of the box (Possibly 75% charge on it). The mounts are very sturdy and do not shake when I hit bumps, even the gnarly ones we all try to avoid (which I sadly hit, A LOT. lol). The mounts also fit multiple size bars, and come with a few bushings to make things nice and snug. The light housing has a nice weight to it, and the light is decently bright. Definitely bright enough to feel safe and visible riding down the road. It’s nice when I have cars bright light me when I run it on Medium (low beam and spotlight together). There are 5 light modes, 4 of which I have included pictures for. (You know you love my Halloween decorations!) It has low beam, spotlight, high beam, flash, and daytime running lights. 10/10 would recommend this bike light!
Review: Bright but kept failing. - This light is wonderful and you can definitely see everywhere you go. That being said I’ve had a few issues. In the middle of early morning rides it has cut out and I’ve had to stop and turn it back on, this last time it cut off the indicator lights remained on but the light would not function. Other than that I enjoyed the light while it worked. The mounting system is great, it’s durable, just won’t work properly for some reason. Update 4/15/2024: After my first review, despite not buying the extended warranty, the company reached out to me and provided the most wonderful customer service I’ve ever gotten from any individual company. They sent me a new unit to uphold their guarantee of the best product available out there. It is no doubt bright and has an excellent battery life. I will use this one and give an updated review to see how this unit performs. I am excited to test it on my daily commutes to and from work.
