Step-by-step explanation:
In night and low-light situations, bicyclists are required to have headlights and taillights for visibility and safety.
Headlights provide illumination to the front of the bicycle, allowing the bicyclist to see and be seen by others on the road.
Taillights, on the other hand, make the bicyclist more visible to drivers approaching from behind.
