I currently have two headlights mounted left and right on the fender/mud guard brackets. These both run on large rechargeable batteries strapped to the underside of the front boom. I want a third light that doesn’t run from those batteries as a backup in case the main lights run out and as an extra light when needed. The remit is it should have it’s own internal rechargeable battery, be bright, compact, have a durable case and externally be smaller than 80mm in width as it will mount on the ICE light mount that came with my QNT. After too much reading I’ve decided to go with the Achort 600 Lumens, 2 LED XPE. I’ll post a detailed review once it’s arrived, mounted and tested.
