Jeep Grand Wagoneer Map Light Bulb Size

The Jeep Grand Wagoneer map light requires bulb sizes 212-2, 105, or 211-2 depending on the specific application. Available information covers a time range from 1986 through 1993.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The Jeep Grand Wagoneer map light specifications cover model years 1986-1993 and reference three distinct bulb sizes: 212-2, 211-2, and 105.
The 211-2 is the most frequently specified bulb across these years, appearing in the 1987-1990 model years.
Both the 211-2 and 212-2 are festoon-type bulbs, meaning they are cylindrical in shape and mount by pressing between two spring clips rather than inserting into a socket.
The 211-2 and 212-2 share identical physical and electrical characteristics: a 41mm length, SV8.5 base, 12 volts, and 12 watts.
Despite their near-identical specifications, the 211-2 and 212-2 carry separate ANSI designations, and fitment should follow the year-specific listing rather than treating them as freely interchangeable.
The 105 bulb is specified for the 1986 and 1991 Grand Wagoneer, and it differs fundamentally from the festoon types in both construction and mounting, using a BA15s single-contact bayonet base.
The BA15s base of the 105 bulb requires a dedicated bayonet socket, making it physically incompatible with the spring-clip housings designed for the 211-2 or 212-2.
The 105 is noted as a variant of the 1156 bulb, though at 13 watts it draws slightly more power than the 12-watt festoon types used in other Grand Wagoneer model years.
All three bulb types conform to ANSI standards recognized in both the United States and Canada, indicating standardized production tolerances across manufacturers.
The 12-volt operating voltage across all three bulb types is consistent with standard automotive electrical systems of that era.
