Product Description Headlights are fundamental to driving and they are a part of the safety circle that actually helps prevent accidents. When getting close to the end of their lives, headlamps shine less brightly, it's quite distracting if one of your headlamps is brighter than the other, and it certainly won't reflect road markings and traffic signs very well. YITAMOTOR high-quality headlights will let all of the light through, allowing your headlights to work the way they were originally made to.
