Front and rear lights, day and night
Cycling has taken some of its best cues from the automotive industry. We can thank cars and motorcycles for suspension and disc brakes, for instance. These days, cars come standard with daytime running lights because cars with DRLs are less likely to be involved in a collision. Applying that logic to bikes is a no-brainer. But not all lights are created equal. Even lights designed for superior brightness may not be particularly effective during daylight hours. A true DRL has a specific focus, flash, and range. Without these three things, you just have a light.
