ABSTRACT:
A lamp socket for an automotive exterior lamp assembly that can be used with a replaceable incandescent bulb. The lamp socket comprises a plastic socket made from nylon 4,6. The lamp socket exhibits reduced outgassing that would otherwise result from photo-oxidative degradation of the polymers in the plastic socket. This helps prevent fogging of the lamp assembly lens and/or reflector for improved performance and aesthetic appearance over the life of the lamp assembly. The incandescent bulb used in the assembly can include a press-sealed end having a sleeve attached over the press-sealed end, and the sleeve can be made from at least one of nylon 4,6, PEI and PPA. The incandescent bulb may also have a molded plastic base, and the base can also be made from at least one of nylon 4,6, PEI and PPA.
