    • A headlight lamp with at least one incandescent filament, which is surrounded by a lamp vessel. The at least one incandescent filament is constructed in such a way that during lamp operation it generates a luminous flux, the value of which is greater than a predetermined permissible maximum value for the luminous flux of the lamp. The lamp vessel has a region of reduced transparency, with the aid of which the luminous flux emerging from the headlight lamp during lamp operation is reduced to a value of less than or equal to the predetermined permissible maximum value.
    • 具有至少一个白炽灯丝的前照灯,其被灯容器包围。 所述至少一个白炽灯丝以这样的方式构造,使得在灯操作期间,其产生的光通量大于灯的光通量的预定容许最大值。 灯具具有透明度降低的区域,借此在灯操作期间从头灯灯出现的光通量减小到小于或等于预定允许最大值的值。
