Abstract:
A device for compensation of voltage drop at light sources of a vehicle, said device comprising:light sources (4a-4n) having a resistance R.sub.0 and connected to a vehicle battery (3);an auxiliary charge device (1) comprising an electric motor (2);said electric motor (2) having an on/off switch (6);said electric motor (2) connected to the vehicle battery (3) and connected parallel to said light sources (4a-4n);a resistor (5) serially connected upstream of said light sources (4a-4n), wherein said resistor (5) is selected, based on said resistance R.sub.0 such that a nominal current I flowing through said light sources (4a-4n) causes a voltage drop .DELTA.E=I.times.R in said resistor (5) that matches a voltage drop occurring when said electric motor (2) is switched on;a first switch (7) connected parallel to said resistor (5) for short-circuiting said resistor (5) when said electric motor (2) is switched on by said on/off switch (6).
