Flashing Lights and Bright Jerseys: Do They Really Make Cyclists Safer?
Briefly

Cyclist visibility is essential for safety, especially during solo rides. Recent studies indicate that employing visibility tools—like flashing rear lights and fluorescent clothing—can lower collision risks. Flashing lights can reduce accidents by up to 19% during daylight, while high-visibility clothing improves detection distance, especially in daylight. Cyclists often feel more secure and confident when equipped with these tools, which can ultimately provide an edge against potential collisions. However, relying solely on bright attire is insufficient without additional visibility strategies like reflective materials and active light sources.
Studies have shown that a flashing rear light during daylight hours can reduce the chance of a collision by as much as 19%. It cuts through visual clutter in a way a static object simply can't.
Some cyclists bristle at the idea of dressing like a traffic cone, but research supports the trend. A Transport Research Laboratory study found that fluorescent clothing increases detection distance during the day - sometimes doubling the distance at which a driver spots a cyclist.
