Additional Notes

The Honda Prelude uses the 168 bulb for the parking light position across the 1983-2001 model years, while the 1979-1982 model years use the 2057 bulb instead.
The 168 is a T10 miniature wedge bulb rated at 12V and 4.9W, making it a low-wattage single-filament lamp commonly used in parking and marker light applications.
The 2057 uses a BAY15d bayonet base rather than a wedge base, which means it is physically incompatible with sockets designed for the 168 bulb.
The 2057 is a dual-filament bulb rated at 12V with a 26.9W high filament and an 8W low filament, drawing significantly more power than the 168.
Because the 168 and 2057 differ in both base type and wattage, they are not interchangeable, and substituting one for the other would require a socket or wiring modification.
The 2057 is described as a brighter variant of the 1157, sharing the same BAY15d bayonet base but with higher wattage output on its primary filament.
Both the 168 and 2057 conform to ANSI standards applicable in the United States and Canada.
The T10 wedge form factor of the 168 allows for tool-free removal in most applications, as the bulb is held in place by the socket itself rather than a locking mechanism.
