Abstract
To prolong the life of a vehicle light bulb by securing the legs of the dipped beam filament by forming a hole in cupped shield, fixing one leg directly to common lead by passing this leg through the hole, and fixing the other leg directly to lead. If the shield vibrates as shown by circled arrows 2 and 2, this vibration is not transmitted to the dipped beam filament. Accordingly, the life of dipped beam filament can be further prolonged.
