Additional Notes

The Honda Prelude uses two distinct bulb types across its license plate lighting specifications: the 168 and the 67, each belonging to a different bulb family with different base types and wattage ratings.
The 168 is a T10 miniature wedge bulb rated at 12V and 4.9W, conforming to ANSI standards applicable in both the US and Canada. Its wedge base design means it is held in place by the socket itself rather than by a locking mechanism.
The 67 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 8W. The BA15s base uses a pin-and-slot locking system, which is physically incompatible with the wedge-style socket used by the 168.
The 67 is described as a lower wattage variant of the 1156. While the two share the same BA15s bayonet base type, they are not the same bulb, and the 1156 draws significantly more wattage than the 67.
The Honda Prelude (1996-2001) uses the 168 bulb for the license plate position. This applies uniformly across all listed model years in that range, with no variation noted.
The 1979-1991 model years are specified with the 67 bulb. Because the 67 uses a bayonet base and the 168 uses a wedge base, these two bulbs are not interchangeable despite both operating at 12V.
The wattage difference between the two specified bulbs is notable: the 67 at 8W draws considerably more power than the 168 at 4.9W, which reflects a difference in socket and circuit design between the two generations of the vehicle.
