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.
