Review on USB Rechargeable Bike Tail Light: 26 Hours of Super Bright LED Illumination, 3 Light Modes for Mountain Bikes, Road Bicycles, Backpacks - Waterproof & Easy Installation by Mark Gardner

Magnus Bold II Light looks bright and charges with Micro USB and LED indicator as described. I've found that turning it on and off, as well as toggling between the LED backlight options, takes a bit of effort. I also have a hard time distinguishing between medium and high intensity settings; However, I found the slow and fast flash options easily recognizable. Although the taillight comes with a lifetime warranty, there is no information as to what that means. Does this include an internal battery? Does it cover the elastic to attach the device to the bike? is a usb cable included? are things I've found prone to such items in the past. It would be nice to have a written explanation with the information accompanying the device. Finally, I would like to see two more features in the rear light: i) a low battery indicator so that it is not detected at night and suddenly the device switches off (I have seen this feature on my headlight and I believe that Lzne may have this feature in a of their taillights and ii) an automatic shut off feature if the bike is inactive after a few minutes (ideally a user programmed time; too many times I've forgotten to turn off the taillight which has drained the battery. The taillight seems to meet all advertised Features, was delivered quickly, appears to be of good quality and at a competitive price so I am giving 5 stars based on my first impressions I will update this account if there are any changes over time I look forward to purchasing my rear light at to use on my upcoming twilight/evening rides.
