I was in need of a light set upgrade now that I am doing more night riding. I realized that the affordable options that I had fitted my bike with were not enough and damn near unsafe. As soon as the package came in I knew it was better. I charged them (which took less than 2 hours for both head and tail light) The safety options on the lights as to not accidentally turn in on and ignite something in your bag is great. The intensity of these lights is ridiculous. I know the models go up to over 1000 lumens but the 500 is more than enough even for those poorly lit streets. I ease of mounting them on your bike is convenient and the silicone straps ensure a tight non wiggling fit. Care and other vehicles are sure to see you weather you are using the steady light modes (3 options) or the blinking (3 more for 6 modes total). Be sure to pick up a light set from Aventon as soon as you can.
