Chrysler New Yorker Map Light Bulb Size

Additional Notes

• The Chrysler New Yorker map light specifications span model years 1956 through 1996, covering four decades of bulb fitment data across multiple bulb families.
• The 1004 bulb is the most frequently specified map light bulb in these records, covering the Chrysler New Yorker from 1956-1966 and again in 1978. It is a dual-filament bulb with a BAY15d bayonet base rated at 12V and 21/5W, making it a variant of the widely known 1157 type.
• The 562 festoon bulb appears across 1972-1977 and 1979-1980. At 44mm in length with end-cap contacts, it operates at 12V and 12W. Festoon bulbs of this type seat between two spring clips rather than inserting into a socket, so housing geometry is a critical fitment factor.
• The 912 wedge bulb is specified for the Chrysler New Yorker across 1982-1984 and again in 1986. Classified as a T15 wedge and a variant of the 921, it runs at 12V and 12W, which is notably higher wattage than the T10 wedge types also present in these specifications.
• The 192 bulb is specified for 1994-1996. It is a T10 miniature wedge type rated at 12V and 3W, making it one of the lowest-wattage bulbs in these records. Despite sharing the T10 form factor with the 906, its wattage differs substantially.
• The 906 bulb, specified for the 1987 Chrysler New Yorker, is also a T10 miniature wedge type but is rated at 12V and 8W. Because the 192 and 906 share the same T10 wedge form factor yet carry different wattage ratings, substituting one for the other would alter the electrical load on the map light circuit.
• The 214-2 festoon bulb is specified for 1981 and 1985. It uses an SV8.5 base with a 41mm length and operates at 12V and 12W. The SV8.5 base type is distinct from the end-cap contact design of the 562, meaning the two festoon types are not interchangeable despite sharing the same voltage and wattage ratings.
• The bulb 90, specified for 1967-1970, uses a BA15s single-contact bayonet base and is rated at 12V and 13W. The BA15s base is a single-filament configuration, distinguishing it from the dual-filament BAY15d base of the 1004 bulb used in earlier model years.
• The 74 bulb, specified for 1989, is a T5 miniature wedge type rated at 12V and 1.4W. The 1895 bulb, specified for 1971, is also a T5 miniature wedge but rated at 12V and 0.9W. Although both share the T5 form factor, their wattage values differ, and neither is interchangeable with the T10 or T15 wedge types found in other model years.
• Across these specifications, the Chrysler New Yorker map light fitment changed bulb types multiple times, and no single bulb type covers the full production span. Direct substitution between model years is not supported by these specifications without confirming the exact bulb type for the target year.
