Hino SG3320 front and rear side marker bulbs utilize 194 and 67 sizes respectively. The replacement chart covers 1993 to 1995 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hino SG3320 uses two distinct bulb types across its side marker positions for the 1993-1995 model years: the 194 at the front and the 67 at the rear.
The 194 is an ANSI-standard miniature wedge bulb in the T10 form factor, rated at 12V and 3.78W, and is among the lower-wattage bulbs found in automotive marker applications.
The T10 wedge base of the 194 requires no locking mechanism for retention; the wedge shape itself holds the bulb within the socket, which distinguishes it from bayonet-style fitments.
The 67 is an ANSI-standard single-filament bulb rated at 12V and 8W, fitted with a BA15s bayonet base, which uses a single locating pin to seat and lock the bulb into its socket.
The 67 is a lower-wattage variant of the 1156 bulb and shares the same BA15s bayonet base, though the two are not interchangeable due to the difference in wattage and light output.
Because the 194 and the 67 use physically incompatible bases, a wedge socket at the front and a bayonet socket at the rear, the two bulb types cannot be substituted for one another regardless of voltage compatibility.
Both the 194 and the 67 conform to ANSI standards applicable in the United States and Canada, indicating standardized dimensional and electrical tolerances across manufacturers producing these bulb types.
