The Hino SG5523 front side marker uses a 194 bulb size while the rear side marker requires a 67 bulb size. The replacement chart covers 1993 to 1995 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 Hino SG5523 uses the 194 bulb for the front side marker position across the 1993-1995 model years.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, conforming to ANSI standards for the US and Canadian markets.
The T10 wedge base on the 194 bulb requires no locking mechanism, as the wedge-shaped base is held in place by tension within the socket.
The rear side marker position on the 1993-1995 SG5523 uses the 67 bulb throughout the same model year span.
The 67 bulb operates at 12V and 8W, making it significantly higher in wattage than the 194 used at the front.
The 67 uses a BA15s bayonet base, which is a single-contact bayonet fitting that locks into its socket with a quarter-turn motion.
The 67 is a single-filament bulb and is classified as a lower wattage variant of the 1156, meaning the two share the same BA15s base type but differ in power output.
Because the 67 and 1156 share a base type, physical fitment into the socket is possible for both, though their differing wattage ratings make them non-equivalent replacements for one another.
