Abstract
The headlight unit has at least one low beam headlight and at least one high beam headlight. The headlight unit is constructed so that it fulfills the different sets of legal regulations for the high beam in both the U.S.A. and Europe. According to the regulations in the U.S.A. the high beam produced by the high beam headlight must have a maximum light intensity in the center of the high beam and at least one required light intensity on the opposing traffic side. The at least one required light intensity on the same traffic side is provided by the low beam propagated from the at least one low beam headlight. This low beam has an asymmetric light-dark boundary that is higher on the same traffic side than on the side of the opposing traffic. According to the European regulations a comparatively higher maximum light intensity is permitted in the center of the high beam and a comparatively lower light intensity is required in the lateral regions. These latter regulations are fulfilled by the high beam produced by the high beam headlight in the headlight unit according to the invention.
