[Willow]

The bulb model for a 125cc motorcycle headlight is X9-H4. Below is relevant information about motorcycle headlights: 1. Function: Motorcycle headlights primarily serve illumination and signaling purposes. The light emitted illuminates the road conditions ahead, enabling safe nighttime riding. 2. Classification: Motorcycle lights can be categorized by light source into halogen tungsten lamps and xenon lamps. Halogen lamps emit light through tungsten filaments with relatively low lumen output, insufficient brightness, high power consumption, and a short lifespan of only 600 hours. 3. Application: Motorcycle headlights (high beam and low beam) are used during nighttime and foggy conditions to clearly see vehicles and pedestrians ahead. However, when meeting oncoming traffic, the low beam should be used to avoid affecting the other party's visibility and prevent collisions.
