Headlight
Description
The low beam lights are projector-type lights which are more compact while maintaining sufticient brightness. Bundlingthe light rays reduces stray light and yields a spotlight-effect which improves visibility during night or foul weather driving.For easier aiming, the headlights are equipped with vertical and horizontal gauges.
NOTE: As the outer lenses are made of a resin material, don't cover the headlights when they a.e turned on.
