Large Motorcycle Headlights Only Shine on One Side: A Safety Measure, Not a Malfunction.
Many people assume that the headlights of large motorcycles are faulty when they only illuminate one side. However, the reality behind this design choice is related to safety concerns and regulations in certain countries.

In countries across Europe and North America, large motorcycles are often required to have their headlights on during the day to enhance visibility for other vehicles, especially in foggy conditions like those frequently encountered in the UK.
Additionally, the presence of dual headlights on motorcycles, while only one is used, ties into the functionality of high and low beams.
In some regions, such as the United States, motorcycles and cars often share the same lanes and travel at high speeds.
When both headlights are illuminated, it can lead to confusion for car drivers, who might mistake a motorcycle for a distant car. This can occur because when both motorcycle lights are on, drivers glancing in their mirrors may perceive the motorcycle as a car far away, when in fact, it is a large motorcycle very close. This misunderstanding can increase the risk of accidents.
However, when only one headlight is lit, it allows car drivers to more easily distinguish the motorcycle in their rearview mirrors, thereby enhancing safety on the road.
