Question

DentroTest · Accepted Answer

The optical assembly of the headlight, especially through the parabolic reflector and the lens or cover, aims to channel the light produced by the lamp. If the light were emitted in all directions indiscriminately, it would lose useful intensity on the roadway and would seriously dazzle other road users. Therefore, the headlight must project the beams in a specific direction (providing the regulatory depth and width) and with suitable light characteristics so that the driver has clear and safe night visibility.
