Dodge Dynasty Map Light Bulb Size

Additional Notes

• The Dodge Dynasty map light bulb specifications span the 1988-1993 model years, covering four distinct bulb types across that range.
• The miniature wedge form factor is the most frequently specified type across these years, appearing in four of the six model year entries through the 168, 906, and 74 designations.
• The 168 and 906 bulbs both follow the T10 wedge form factor and operate at 12V, though they differ in wattage: the 168 draws 4.9W while the 906 draws 8W. This wattage difference means the two are not interchangeable despite sharing the same physical base type.
• The 74 bulb, specified for the 1988-1989 Dynasty, is a T5 miniature wedge rated at 12V and 1.4W. The T5 wedge is physically smaller than the T10, making it incompatible with sockets designed for T10 bulbs.
• The 1993 Dynasty uses the 211-2, a festoon bulb with a 41mm length and an SV8.5 base, rated at 12V and 12W. Festoon bulbs seat by spring tension between two end caps rather than inserting into a wedge socket, so this type is not interchangeable with any of the wedge bulbs listed for other model years.
• All four bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada.
• The 1990 Dynasty uses the 906 bulb, and the 1991-1992 Dynasty uses the 168 bulb. Both are T10 wedge types, but the socket and intended wattage for each model year should be verified before treating them as substitutes for one another.
• At 12W, the 211-2 festoon bulb specified for the 1993 model year draws considerably more power than any of the wedge bulbs listed for earlier years, reflecting a distinct electrical load for that application.
