Why do I need lights on my bicycle?

Why do I need lights on my bicycle?    

          The idea of daylight visibility is simple- be seen on the road, during the day. Cyclists and cars share the same roads and streets and need to be aware of one another. Cars come standard with daytime running lights, brake lights, turn signals to make them easier to see and communicate where they are, and where they are going. It is no different for cyclists. The idea of daylight visibility is the idea of taking every precaution to make sure that as a cyclist you can be seen by the all users of the road. Why is daylight visibility important? 

  • 80% of cycling accidents occur during the day
  • 40% of US cycling fatalities hit from behind2
  • Studies show riders overestimate their visibility by 700%

How to increase daylight visibility

           Properly attaching a daylight visible light that is set in the proper day flash mode is the easiest way to add an element of daylight visibility to any bike and cyclist. Remember that day flash modes are great for use during the day, but can be overwhelming for use after dark. Each light has specific night modes better suited for night time use.

           Use your movement on as an added way to increase your visibility. Your feet are moving. Highlight that movement by wearing florescent or bright colors on your feet during the day and reflective in the dark.

           Dress in contrast! Wearing all one color may look cool but to be more visible to drivers wearing brighter tops next to your black shorts creates a contrast line across your torso.
