Large-displacement motorcycles often only light up one side, making many people think that the light is broken. However, the reality behind the fact that the light only shines on one side is related to safety reasons and regulations in some countries.
In European and North American countries, large-displacement motorcycles are often required to have their headlights on during the day to increase visibility for other road users, especially in foggy conditions like in the UK.

Furthermore, the fact that motorcycles are equipped with dual headlights but only use one light is related to the function of the low beam and high beam.
In some countries, such as the US, there are many places where motorcycles and cars will share the same lane and travel at high speeds.
When both headlights are on, car drivers can easily confuse a motorcycle with a car. Because when both motorcycle headlights are on, the car driver looks in the mirror and mistakenly thinks it is a car that is far away, but in reality, it is a large-displacement motorcycle that is very close. This can lead to accidents.
But when only one side of the headlight is on, this makes it easier for car drivers to distinguish in the rearview mirror, helping to ensure safety when traveling on the road.
