Vehicle lamp base having integrally formed spring to bias reflector

An automotive lamp capsule (32) adapted to be received in a vehicle lamp reflector (12) mounted to a vehicle chassis, the lamp capsule comprising:

• a lamp base (34);
• a light source (38) having an envelope defining an optical axis (39) extending from a proximal end adjacent the lamp base to a distal end, and wherein electric leads (90) for the light source extend from the envelope through the proximal end;
• the base (34) having a wall (43) defining a passageway (45) for the electrical leads (90) to be received therein to form an electrical pathway for connection to an external power supply to energize the light source;
• and
• a retainer (36) interconnecting the light source (38) and the base (34);
• wherein the wall (43) of the base further defines a circumferentially extending exterior locating surface (44) configured to abut an interior socket surface (24) of the automotive lamp reflector (12), the wall of the base further comprising a spring (5) formed monolithically with the wall, said spring (5) extending radially beyond the exterior locating surface (44).
