Bontrager, B&M, Cygolite et al have different motivations than yours truly. The light manufacturers are tasked with the mission of socially engineering a significant number of cyclists to use a product designed for nightime use during daylight hours. Why? Because the VAST number of cyclists do little or no riding at night. I'm certain Kevin is a Child of God and his motives are pure. Bontrager, less so I am afraid. Were they stand up engineers they would have admitted that daytime running lights don't achieve any greater daytime safety than hi-viz helmets and jerseys. For a cyclist that never rides at night, the need to buy an expensive head and tailight combo is ... zero.
