The filaments for high beam and low beam are in respectively parallel planes, and the axis of the low beam filament forms an angle alpha which is less than 90 DEG with the lamp axis, or seal beam headlamp axis, respectively, the angle being suitably between about 30 DEG and 60 DEG , and preferably about 45 DEG , upon projection of the lamp axis, in parallel, in the plane which includes the axis of the filament. The inclination of the low beam filament facilitates adjustment of the headlamp to provide, reliably, glare-free road illumination in accordance with SAE standards. |
