Giro Mountain/Urban Recreational Helmet Vent Light
The red Recreational helmet light for MTB and urban helmets by Giro is suitable as an additional rear light to increase your visibility. You attach it by simply inserting it into a vent at the back of your head. You can choose between two light modes: continuous and flashing. In flashing mode, the two LEDs light up for up to 130 hours before you need to change the batteries.
