Dark roads and trails are no match for Light and Motion's impressively bright Stella 300 Dual Lighting System. Its two high-output LED bulbs boast 3 steady modes plus a flashing mode and provide up to 300 lumens to light your way. And, the powerful Lithium-Ion battery delivers run times ranging from 3 to 12 hours (over 100 in flashing)! Plus, you can adjust the angle of the two headlights independently for maximum illumination. What's more, the total system weight of only 300 grams won't weigh down your night-riding rig.
