Full-face helmets provide more protection for the face and jaw in the event of a crash, making them better for more aggressive and high-speed cycling such as downhill mountain biking or BMX racing.

Bicycle traffic lights have two red lights to make them more visible to cyclists. The two red lights are placed side by side, making it easier for cyclists to see the signal from a distance and in their peripheral vision. This helps to ensure that cyclists can clearly see when they need to stop, promoting safety at intersections. Additionally, the two red lights can help prevent confusion or misinterpretation of the signal, as it is clear that both lights being red means the cyclist must stop. **
