PCT No. PCT/SE96/00023 Sec. 371 Date Jul. 16, 1997 Sec. 102(e) Date Jul. 16, 1997 PCT Filed Jan. 12, 1996 PCT Pub. No. WO96/22194 PCT Pub. Date Jul. 25, 1996A method for controlling the full-beam headlights of automotive vehicles, particularly cars, which headlights are provided with dischargeable light sources. The light source (2) is chosen so that when supplying the light source with its nominal power it will produce a luminous flux which greatly exceeds the luminous flux that is standard for full-beam lighting, supplying the light source (2) with a lower power causes the light source (2) to produce a luminous flux which is normal for full-beam lighting. A power level selection (7; 10, 4) is provided for enabling the light source (2) to be supplied selectively with the lower power or with its nominal power. |
