What can fail
The socket holder in the fog light is pressed into the lamp casing. Heat from the bulb can expand it, pushing it backward. Repeated expansion combined with vibration during driving may cause the socket holder, bulb holder, and wiring to separate from the fog light.
What the fix does
A spring will be installed to keep the socket holder from separating from the lamp casing.
