Additional Notes

The 2057 bulb is the most frequently specified size across the Chevrolet Camaro tail light data. It is an ANSI-standard dual-filament bulb with a BAY15d bayonet base, rated at 12V with filaments drawing 26.9W and 8W respectively, making it a higher-output variant of the 1157.
The 1157 bulb shares the same BAY15d bayonet base as the 2057 but operates at lower wattages of 21W and 5W. Both bulbs use the same base type, though their filament outputs differ, which is a relevant fitment consideration for the outer tail light position.
The Camaro (1967-1983) outer tail light uses the 1157 bulb, while the 1984-2002 model years transition to the 2057. Both are dual-filament bayonet-base bulbs, but they are not identical in output.
The 194 bulb is specified for the inner tail light position across the 1993-2002 Camaro. It is a miniature T10 wedge bulb rated at 12V and 3.78W, functioning as a low-draw marker or indicator lamp rather than a primary brake or turn signal source.
The 12961 is a Philips part number rather than an ANSI standard designation. It is a T10 wedge bulb with a W2.1x9.5d base, rated at 12V and 5W, and is specified for 2016-2018 Camaros equipped with halogen capsule headlamps in the outer tail light position.
The 7443 is a dual-filament T20 wedge bulb rated at 12V with filaments at 21W and 5W. It is specified for the 2013-2014 Camaro outer tail light with halogen headlamps, and it is not interchangeable with the single-filament 194 or the bayonet-base 2057 and 1157 bulbs.
The 3157 is a dual-filament T25 wedge bulb rated at 12V with filaments at 27W and 7W. It is specified for the 2010-2013 Camaro outer tail light and shares a wedge base format with the 7443, though the two are not interchangeable due to differing sizes and pin configurations.
For 1995-1997 Camaros, the outer tail light specification splits by trim configuration. Units with an export marker lamp use the single-filament 1156 bulb with a BA15s bayonet base, while units without that lamp use the dual-filament 2057. The 1156 and 2057 use different base types and filament counts, making them non-interchangeable.
The 1156 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 21W. Its base visually resembles the BAY15d base used by the 1157 and 2057, but the locating pin positions differ, preventing cross-installation between these base types.
Across the full outer tail light specification range, four distinct base types are present: the BAY15d bayonet base (1157, 2057), the BA15s bayonet base (1156), and wedge bases in T10 (194, 12961), T20 (7443), and T25 (3157) sizes. None of these base types are mutually interchangeable.
