Acura Vigor front and rear side marker bulbs utilize 168 and 2057 bulb sizes respectively. The replacement chart covers 1992 to 1994 vehicle production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Acura Vigor (1992-1994) uses two distinct bulb types across its front and rear side marker positions, with each position using a single consistent bulb type throughout the entire production run.
The front side marker on the 1992-1994 Acura Vigor takes the 168 bulb, a T10 miniature wedge type rated at 12V and 4.9W, conforming to ANSI standards for the US and Canadian markets.
The T10 wedge base on the 168 bulb is a pinless design that seats by friction, meaning the bulb is held in place by the socket walls rather than a locking mechanism.
The rear side marker across all three model years uses the 2057 bulb, which operates on a BAY15d bayonet base at 12V with a dual-filament configuration rated at 26.9W and 8W respectively.
The dual-filament nature of the 2057 means it carries separate circuits for two brightness levels, a characteristic relevant to its function in a rear side marker position where varying intensity may be required.
The 2057 is a brighter variant of the 1157 bulb. Both share the BAY15d bayonet base, though their wattage ratings differ, which affects their interchangeability in certain applications.
The 168 and 2057 are physically incompatible with each other, as the T10 wedge base and the BAY15d bayonet base are entirely different socket types requiring separate housings.
Both the 168 and 2057 conform to ANSI standards applicable to the US and Canadian markets, indicating standardized electrical and physical tolerances across compliant manufacturers.
