There's a particular kind of confidence that comes from having a proper light on your helmet. Suddenly, that dark corner you've been approaching looks considerably less mysterious, and the trail ahead becomes a little easier to judge. The Exposure Lights Zenith 4 takes that confidence seriously, delivering an enormous 2360 lumens from a compact, beautifully engineered front light. Designed for demanding night rides, technical descents and riders who enjoy staying out long after sunset, it's the sort of equipment that makes darkness feel considerably less intimidating. Unfortunately, it still won't make that questionable line choice any better.
The Zenith 4 uses three powerful LEDs and a focused 12° spot beam to illuminate the trail ahead, helping you pick out obstacles, corners and changes in terrain with impressive clarity. Exposure's clever TAP Technology lets you switch between lighting modes simply by tapping the helmet or light body, saving you from fumbling around for a tiny button in the dark. Despite its powerful output, the Zenith weighs just 150g, making it a practical option for helmet mounting. Add fast USB-C charging, up to 36 hours of runtime and rugged UK-engineered aluminium construction, and you've got an exceptionally capable light that's ready for serious night riding. Exposure has even included helmet and handlebar mounting options, so you can decide exactly where all that illumination belongs.
