The Acura Vigor front and rear turn signal bulbs both utilize a 3497 size bulb for proper operation. The replacement chart covers 1992 to 1994 model 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 3497 bulb is the sole turn signal bulb type listed for the Acura Vigor, covering both front and rear positions across the 1992-1994 model years.
The 3497 is an ANSI-standardized bulb recognized in both the United States and Canada, operating at 12 volts with a power rating of 21 watts.
As a single-filament bulb, the 3497 serves one lighting function per socket, which is consistent with its dedicated turn signal application.
The 3497 uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin offset on the base collar, distinguishing it from dual-contact bayonet variants.
The 3497 is a variant of the widely used 1156 bulb type, meaning it shares the same BA15s base and general electrical characteristics, though the two designations are not always interchangeable without confirming voltage and wattage tolerances for a specific socket.
