Technically speaking , xenon lighting is less irritating than halogen lamps. This is because the light darkness transition border are much more clearly defined. Less light is reflected into the eyes of oncoming drivers.
The increased light output is used to give more homogeneous light distribution and to improve the illumination of the verges. The above are only achieved if the following 3 International regulation conditions are met.
The headlamps must be correctly aligned according to the regulations.
The vehicle must be fitted with an automatic headlamp leveling system.
The vehicle is fitted with an automatic headlight cleaning system. Without such the dirt acts as a diffuser for the light and distributes it in areas beyond the prescribed range.
