The Autocar C / DC features 97 bulb size specifications for both front and rear side marker positions. The replacement chart covers vehicle production spanning 1981 to 1986.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Autocar C / DC uses the 97 bulb for both front and rear side marker positions across the 1981-1986 model years.
The 97 is an ANSI-standardized bulb recognized in both the United States and Canada, operating at 12 volts with a 13-watt output.
It uses a BA15s bayonet base, which is a single-contact base type that locks into its socket with a twist-and-push motion.
The 97 is a single-filament bulb, meaning it serves one lighting function rather than switching between two brightness levels.
The 97 is a variant of the more widely known 1156 bulb, though the two are not identical and direct substitution without confirming wattage and base compatibility is not advised.
The uniform use of the 97 across all six model years and both marker positions means a single bulb type covers the full side marker fitment for the Autocar C / DC in this production span.
