On some vehicle equipment levels, socket illumination is via Light Emitting Diode (LED) instead of a bulb. These LEDs are integrated with the illumination housing and cannot be serviced or replaced separately. Various versions of illumination housing with bulb exist. One version allows separate replacement of the illumination bulb, and another where the bulb cannot be serviced or replaced separately. In this case, the entire illumination housing must be replaced. There are different versions of the sockets and cigarette lighter sockets due to different installation locations and construction. The differences are primarily In the length and type of electrical connectors. On sockets or cigarette lighter sockets with an electrical cable pig tail, additional work may be necessary to access the connector.
