Abstract
In a bulb assembly of a vehicle headlight the bulb has a socket formed with an outer annular groove which conically converges towards a filament positioned in a lower portion of the bulb. An O-ring inserted into the groove seals the bulb against a headlight reflector in assembly. The width of the groove in the axial direction of the bulb is selected so that upon pulling the bulb out from the reflector the O-ring performs a rolling motion so that a required pulling force is substantially reduced and a danger for a user injury is prevented.
