The Switch Daybright front light & Flare Daybright rear light are super bright, compact & designed for use day & night. They pack a punch with 350 lumens of front light & 75 lumens of red rear light. Both have side illumination providing 360 degree visibility. The Switch will run for up to 24 hours on a pulsing mode & 3 hours on 350 Lumens. The QR bracket makes it quick & easy to add to your bike for daily use. The Optimised Mode Selector means that you can easily select from a concise number of programs to provide the optimum lighting for your ride. Overall this is a great light to own if you are the daily commuter around towns & cities. There are now more cars on the road than ever & modern motoring life is full of distractions – radio, satellite navigation, & hands free mobile phones to name a few… 80% of all traffic accidents involving cyclists occur during the daytime (source: ROSPA 2014).
