Bright as a small sun attached to your handlebars. Brompton’s front LED, battery-powered light will run for about 50 hours on 3 AAA batteries.
According to the manufacturer, there are three functions: steady, flashing, and off. I think off doesn’t count as a function, but I do think this is a great front light on any bike. High visibility, quick release is easy to use, and cylindrical shape fits into any pocket so you’ll never lose it.
