Abstract

An illumination device for an exterior rearview mirror of a vehicle comprises a bulb holder which comprises a pair of stamped terminals and a housing which is preferably injection molded about the stamped terminals. One end of the stamped terminals provides for connection to a light bulb or other illumination source, while the other end of the stamped terminals provides for electrical connection to a vehicle or mirror wiring harness. Preferably, the body of the bulb holder is molded from a soft plastic material to facilitate easy insertion and removal of the bulb holder in the mirror assembly, and to further ease connection of the vehicle wiring harness to the wiring terminals. The soft plastic molding further provides a water-tight seal between the body and the stamped terminals and between the body and the illumination device of the rearview mirror assembly.

12. The light module of claim 9, wherein said flexible polymeric material comprises a durometer Shore A hardness of between approximately 60 Shore A and 90 Shore A.

13. The light module of claim 9, wherein said flexible polymeric material comprises a durometer Shore A hardness of approximately 60 Shore A.

14. The light module of claim 1, wherein said housing comprises a mounting portion, said mounting portion being at least partially insertable through a correspondingly formed opening in said light module.

15. The light module of claim 14, wherein said housing comprises a lip portion which is engagable with said light module as said mounting portion is at least partially inserted through said opening in said light module.

16. The light module of claim 1, wherein said bulb holder is detachably mountable to said light module.

17. The light module of claim 1, wherein said light module is operable as at least one of a brake lamp, a turn signal indicator, and a security light.

18. The light module of claim 1, wherein said at least two first terminals are engagable with one of an incandescent bulb, a halogen bulb, an incandescent fuse bulb, a vacuum fluorescent bulb, a light emitting diode, a phosphorescent element, electro-illuminescent sources, and semiconductor laser sources.

19. The light module of claim 1, wherein said bulb holder comprises at least four first and second terminals, said at least four first terminals being engagable with corresponding portions of at least two illumination bulbs.

20. An exterior rearview mirror assembly for a vehicle comprising:

a mirror housing;

a reflective element housed within said housing;
