Adapt.

Daylight Savings Time may be your sworn enemy, but you can't stop it from arriving every year. We'd never suggest that you give up all hope and hang up your bike for the season; instead, we'd just say it's probably time to break out a light and your best reflective kit. Whether you're a commuter or a recreational rider looking to extend the season (or a little of both), mount the Sirius Mk5 Headlight onto your frame to light the way on dim, post-sunset streets. As the sky turns from orange to dark purple, the Sirius Mk5's 550 lumens will keep you seeing and seen on everything from country lanes to crowded city bike lanes.

Exposure Lights' specifically designed the Sirius Mk5's beam to cast a wide, flat glow to illuminate the road in front of you, and it also offers some side illumination to prevent blind spots. A choice between steady and pulsing modes keeps things simple when you'd rather focus on riding, and an easy-to-read fuel gauge keeps you informed on battery life. Since the Sirius Mk5's battery recharges using a USB cable, you can plug it in anywhere you can access a USB port for quick recharges on-the-go. A CNC-machined aluminum body shields the light's internals from unexpected thunderstorms and late-season weather in a streamlined, lightweight package that can handle its share of bumps and bruises.
