Double-filament incandescent lamp for automotive vehicle front lighting

Lamp for automotive vehicle front lighting, comprising

• a base for mechanical and electrical connection to an automotive headlight,
• a burner fixed to said base, said burner comprising a sealed transparent vessel,
• at least a first and a second filament arranged within said vessel,
• a baffle arranged proximate to said first filament to shield said second filament from said first filament,
• where when said first filament is supplied with a supply voltage of 13.2 V it is operated at an electrical power greater than 35 W and less than or equal to 38 W, and light with a luminous flux of 500-700 lm is emitted,
• and where when said second filament is supplied with a supply voltage of 13.2 V it is operated at an electrical power greater than 35 W and less than or equal to 38 W, and light with a luminous flux of 800-1,000 lm is emitted,
• wherein each of said first and second filaments are comprised of a filament wire wound around a filament axis,
• where the number of winding turns for each of said first and second filaments is 16-23,
• wherein said base comprises a reference protrusion defining a symmetry plane (X, R), the symmetry plane including a longitudinal axis (X) of the lamp and a reference direction (R) extending radially from the longitudinal axis (X) into a direction of a center of the reference protrusion,
• where said filaments and said baffle are arranged symmetrical to said symmetry plane (X, R).
