What Our Gearhead(R) Experts Are Saying:"The Link MK4 DayBright Light Set is the light I recommend to urban commuters who want to be genuinely seen rather than just technically lit. Mounting it on the helmet puts it above the clutter of parked cars and traffic, and the DayBright Pulse Pattern is aggressive enough to catch attention even in full daylight. At 45 grams, it disappears on the helmet completely."City riding demands visibility from every direction, and the Exposure Link MK4 DayBright Light Set delivers it from a single compact unit mounted where it matters most. At 45 grams, it sits on the helmet without adding any noticeable weight, and the DayBright Pulse Pattern combined with 360-degree visibility means drivers and pedestrians notice it before they notice anything else on the bike. USB-C charging gets it back to full in 90 minutes, and IP65 waterproofing keeps it running through whatever the commute throws at it.
