The powerful, all-round adjustable Haven PERFORMER MINI front light has a secure attachment to the handlebars and fork and is equipped with two powerful LEDs, a USB chargeable battery and six lighting modes. Before first use, fully charge the battery and use it until it completely runs out, this will format the battery properly. Mount the light on the handlebars or fork using an elastic strap that ensures perfect stability even in the field. You can easily change the lighting mode with the button on the top of the lamp. This button also has 4 indicators that indicate the battery charge level. If 4 bars are lit, the battery is fully charged, if 1 bar is lit, the battery is almost empty. For the longest battery life, we recommend fully charging and discharging the battery at least once every three months.
