Abstract: A light bulb includes a seat having a first engaging point and a first contact point respectively formed on a bottom face of the seat to correspond to a second engaging point and a second contact point of a light bulb socket. A first end of the first wire engages with the first engaging point of the seat and a second end thereof engages with a first end of a first filament received in the second enclosure. A first end of the second wire engages with the second engaging point of the seat and a second end thereof engages with a first end of a second filament received in the third enclosure. The third wire has a first end engaging with a side wall of the seat and a second end engaging with both second ends of the first and second filaments.

Abstract: A vehicle light bulb has a glass bulb and a base for receiving the glass bulb. A flat portion is used to seal a bottom of the glass bulb, and at least one filament is provided inside the bulb and connected between two legs that extend out the flat portion. The base is mainly made up of a holder and a plate extending from a bottom of the holder, wherein the holder has a top defined with a slot for receiving the flat portion. At least two apertures are defined in a bottom of the plate. When the glass bulb is received in the base, the two legs individually extend through the apertures so as to electrically connect in a socket of a vehicle light, such as a brake light.
