Additional Notes

The bulb type 67 is an ANSI-standardized single-filament bulb operating at 12V and 8W, fitted with a BA15s bayonet base. It is regarded as a lower wattage variant of the 1156 bulb.
The bulb type 1157 is an ANSI-standardized dual-filament bulb operating at 12V with a dual wattage rating of 21W and 5W, fitted with a BAY15d bayonet base.
The BA15s base of the 67 and the BAY15d base of the 1157 are physically distinct and not interchangeable. The BAY15d base includes offset locating pins to prevent incorrect installation, while the BA15s base has symmetrical pins.
The dual-filament design of the 1157 serves two independent circuits, whereas the single-filament 67 serves only one. This difference in filament count reflects a functional distinction relevant to fitment.
The Hino SF17 used the 1157 bulb for the license plate position in the 1988 model year, then transitioned to the 67 bulb for the 1989-1991 model years.
The wattage difference between the two bulb types is notable. The 1157 draws up to 21W on its primary filament, while the 67 draws only 8W, making them electrically incompatible as direct substitutes despite both operating on 12V systems.
