Additional Notes

The Chevrolet Corvette front fog light uses three distinct bulb types across its model history: the 9145 (2005-2013), the 899 (1997-2004), the 896 (1991-1996), and the 880 (1987-1990).
The 9145 is a single-filament halogen bulb rated at 12V and 42W, fitted with a PY20d base, and certified to ANSI standards for the US and Canadian markets.
The 899 and 896 share the same electrical rating of 12V and 37.5W and both use a PGJ13 base, though they carry different ANSI designations and are not confirmed interchangeable by the specifications.
The 880, used in the front fog light position from 1987-1990, operates at 12V and 27W with a PG13 base, which is physically distinct from the PGJ13 base found on the 896 and 899 bulbs.
The rear fog light on the Corvette uses two bulb types across its listed model years: the 3156 (2005-2013) and the 1156 (1997-2004).
The 3156 is a single-filament wedge-type bulb in the T25 form factor, rated at 12V and 27W, requiring no separate base socket in the traditional sense due to its wedge-style contact design.
The 1156 uses a BA15s bayonet base and is rated at 12V and 21W, making it a lower-wattage option than the 3156 that replaced it in the 2005 model year rear fog position.
The base types across all listed fog light bulbs (PY20d, PGJ13, PG13, wedge/T25, and BA15s) are physically incompatible with one another, meaning substitution between bulb families is not supported by the specifications.
All six bulb types listed across both fog light positions conform to ANSI standards applicable to the US and Canadian markets.
Every bulb listed in these specifications is a single-filament type, which is consistent with fog light applications that require a dedicated, non-switchable light output rather than dual-intensity operation.
