Patent ID: 8084928

Claim:
A halogen incandscent lamp with two incandescent filaments ( 21 , 22 ) arranged within a lamp vessel ( 10 ), a first incandescent filament ( 21 ) being designed for operation at a higher electrical power than the second incandescent filament ( 22 ), wherein the second incandescent filament ( 22 ), in order to implement a daytime running light function, during operation at a standard operating voltage, is designed for an electrical power which is lower than the electrical power of the first incandescent filament ( 21 ) by a factor of 2.5 to 4, and wherein the second incandescent filament ( 22 ) is in the form of an incandescent filament with a single coil and has a pitch factor in the range of from greater than or equal to 1.65 to less than or equal to 2.0 and is constructed in such a way that it can be operated in a dimmed state at an operating voltage lower than the standard operating voltage in order to implement a positioning light function.
