Serious about visibility.

Arguably the most high-tech light designed specifically for urban riding that we sell, the Exposure Sirius Mk3 Headlight is determined to help you see and be seen.


The Sirius enjoys a host of features that makes it an Exposure — which is to say, from a company that takes bike lighting, well, seriously. The light's housing is beautifully machined, and inside is a single 400-lumen XPG LED. That means huge power without huge power consumption, allowing the Sirius to last up to 36 hours on a single charge, depending on which operating modes you engage. Those modes are easy to cycle through, too, given Exposure's Optimized Mode selector that lets you quickly access whichever mode you prefer at a given moment. The cable-free light is rechargeable, weights a mere 84 grams, and easily attaches to your handlebar with the included mount.
