Dark roads and trails are no match for Light and Motion's impressively bright Stella 400 Dual Lighting System. Its two high-output LED bulbs boast 3 steady modes plus a flashing mode and provide up to 400 lumens to light your way. And, the powerful Lithium-Ion battery delivers run times ranging from 2.5 to 10 hours! Plus, you can adjust the angle of the two headlights independently for maximum illumination. What's more, the total system weight of only 313 grams won't weigh down your rig.
