You'd never expect this much power packed into one cubic inch, but we did exactly that. Packed with more technology than meets the eye, the new Dice 150 fires up the night with an incredible 150 lumens, and stands out in broad daylight with intense lightning-like flashes. It also senses day and night, automatically switching to the optimal flash mode. Engineered for road cyclists, it uses a low profile, flexible mount designed for most handlebars including aerobars.
