plastic socket 1
OEM plastic socket has loose tolerances. Vibration combined with contact's springs cause bulb posts to gouge plastic, push outward, and lose contact.

old and new - rear
A rivet was used to add ground lead to back of new assembly (socket didn't come with one). Dielectric grease was used on any surface not powdercoated to protect it from the elements.

new front 2
It may not be that pretty, but it is a huge improvement and it will solve all of the bulb contact problems. With the plastic lenses installed, there is no visible difference between new and OEM.
