Exposure Lights Sirius Mk9 DayBright Front Light
Powerful enough for unlit roads at night, yet small enough to use on every ride, Exposure Lights’ Sirius Mk9 DayBright Front Light can muster up 850 lumens, or run for up to 36 hours on its lowest setting. The open lens design means that it can be seen from the side and the DayBright pulse pattern alerts traffic even during the daytime.
The Fuel Guage shows how much battery charge remains and there are multiple modes and programmes available so that there will always be enough light for the ride, no matter its length. It is supplied with a handlebar mount but can also be helmet mounted with the optional kit, and paired with a more powerful bar light for off-road use.
