Description	Bulb Size
ANSI standard (US & Canada). Single-filament bulb with BA15s bayonet base. Variant of 1156. 12V, 13W.	97

The Autocar DK uses the 97 bulb in both the front and rear side marker positions across the 1983-1988 model years.
The 97 is an ANSI-standardized bulb recognized in both the United States and Canada, operating at 12 volts and 13 watts.
It is a single-filament bulb, meaning it serves one lighting function rather than combining two, such as running and braking, into a single unit.
The 97 uses a BA15s bayonet base, which is a single-contact bayonet mount that locks into its socket with a twist rather than a threaded connection.
The 97 is a variant of the more widely known 1156 bulb, though the two are not necessarily interchangeable despite their shared base type, as wattage and voltage ratings may differ between variants.
Because the same bulb size is specified for both front and rear side marker positions, a single bulb type covers all side marker replacements on the Autocar DK for the full 1983-1988 production span.
