GMC Jimmy Map Light Bulb Size

Additional Notes

• The GMC Jimmy map light specifications reference four distinct bulb types across the 1989-2001 model years: the 168, 194, 906, and 212-2.
• Three of the four bulb types, the 168, 194, and 906, share the T10 miniature wedge form factor, meaning they use the same physical base style despite differing wattage ratings.
• Although the 168, 194, and 906 bulbs share the T10 wedge base, their wattage values differ: the 194 draws 3.78W, the 168 draws 4.9W, and the 906 draws 8W, which makes them non-interchangeable without consideration of the electrical load.
• The 212-2 is a festoon-style bulb with an SV8.5 base and a 41mm length, operating at 12V and 12W, and it is physically incompatible with the T10 wedge socket used by the other three bulb types in these specifications.
• The GMC Jimmy (1995-1997) uses the 212-2 festoon bulb for the map light, with 1993 also sharing that same specification, making it the most frequently listed bulb type across these model years.
• All four bulb types listed in these specifications conform to ANSI standards recognized in both the United States and Canada.
• The 1994 GMC Jimmy is the only model year in these specifications to use the 194 bulb for the map light, setting it apart from adjacent years that use different bulb types.
• The 1989-1991 GMC Jimmy models share the 906 T10 wedge bulb for the map light, which at 8W draws notably more power than the 194 and 168 bulbs used in other listed years.
