Chevrolet Corvette Trunk Bulb Size

Additional Notes

• The Chevrolet Corvette trunk bulb specifications cover model years 1955 through 2019, with several distinct bulb types appearing across that span.
• The 12961 is a Philips-branded miniature wedge bulb with a T10 form factor and W2.1x9.5d base, rated at 12V and 5W. It is the trunk bulb for the Corvette from 2014-2019.
• The 562 is a 44mm festoon bulb with end-cap contacts, rated at 12V and 12W. It serves as the trunk bulb across two separate periods: 1995-1996 and 2008-2013, making it the most frequently specified bulb type in these trunk specifications.
• The PC168 and PC175 designations indicate T10 wedge bulbs fitted with a printed circuit board twist-lock socket, a mounting style typically associated with instrument cluster applications. The Corvette uses PC168 for most years from 1997-2007, with PC175 appearing specifically in 2001 and 2005.
• PC168 and PC175 share the same T10 wedge form factor but use different printed circuit board socket configurations, meaning the two types are not interchangeable despite their physical similarity.
• The 906 bulb is a T10 miniature wedge type rated at 12V and 8W. It is specified for the Corvette trunk from 1987-1990 and again in 1992-1994, with the exception of 1991, which uses the 561 festoon bulb instead.
• The 561 and 562 are both 44mm festoon bulbs with end-cap contacts rated at 12V and 12W. Their shared physical and electrical characteristics indicate a high degree of interchangeability, though they carry separate ANSI designations.
• The 1003 and 1156 are both single-filament bulbs with a BA15s bayonet base, each rated at 12V and 21W. Despite their identical electrical and base specifications, they carry separate ANSI designations and appear in different model year groups: 1156 in 1962-1965 and 1003 in 1958-1961 and 1966-1970.
• The 94 bulb is a dual-filament type with a BAY15d bayonet base, rated at 12V with a 21W/5W output, and is noted as a variant of the 1157. Its dual-filament design distinguishes it from all other bulb types in these specifications. It is the trunk bulb for the 1955-1957 Corvette.
• The T10 wedge form factor appears across multiple distinct bulb designations in these specifications, including the 12961, 906, 194, 168, PC168, and PC175. Despite sharing the same physical form factor, differences in wattage and socket type mean these types are not universally interchangeable.
