Chevrolet Corvette Dome Light Bulb Size

Additional Notes

• The Chevrolet Corvette dome light specifications reference five distinct bulb types across the model years covered: the 212-2, 214-2, 211-2, 90, 1895, and 1004.
• The 212-2, 214-2, and 211-2 are all festoon bulbs sharing a 41mm length and SV8.5 base, each rated at 12V and 12W under the ANSI standard. Despite their near-identical physical and electrical characteristics, they carry separate part designations and are not listed as interchangeable within these specifications.
• The Chevrolet Corvette uses the 212-2 festoon bulb for the dome light in the 2005-2007 model years, as well as in 1968, 1974-1976.
• The 214-2 festoon bulb is specified for the 1977-1982 and 1984 model years. The shared SV8.5 base and 41mm length of the 214-2 are physically consistent with the 212-2 and 211-2, yet fitment decisions should follow the exact designation listed per year rather than assuming cross-compatibility.
• The bulb designated 90 uses a BA15s single-contact bayonet base and is rated at 12V and 13W. This base type is a single-pin bayonet mount, distinguishing it mechanically from the festoon and wedge types also present in these specifications.
• The 90 bulb is specified for the 1962-1967 and 1972-1973 model years of the Corvette dome light position.
• The 1895 is a T5 miniature wedge bulb rated at 12V and 0.9W, a substantially lower wattage than any other bulb type in these specifications. It is listed for the 1969-1970 model years.
• The 1004 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 21/5W output across its two filaments. The BAY15d base uses offset pins to prevent incorrect single-filament substitution, and the 1004 is noted as a variant of the 1157.
• The 1004 is specified for the dome light position across the 1955-1960 model years, representing the earliest entries in these specifications.
• The 211-2 festoon bulb is listed solely for the 1961 model year in these specifications, placing it as a transitional designation between the 1004 used in prior years and the 90 bulb adopted from 1962 onward.
