Additional Notes

The Honda Civic parking light specifications cover model years 1973-1991, with two distinct bulb types used across that span.
The 168 bulb is a T10 miniature wedge type rated at 12V and 4.9W, conforming to ANSI standards for the US and Canadian markets.
The 2057 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a two-wattage output of 26.9W and 8W, also conforming to ANSI standards for the US and Canadian markets.
The dual-filament design of the 2057 means it supports two independent circuits within a single bulb, which is a characteristic associated with combined stop and tail light functions.
The 2057 is noted as a brighter variant of the 1157, sharing the same BAY15d bayonet base, which means the two types are physically interchangeable in terms of socket fit, though their wattage outputs differ.
Honda Civic models from 1973-1983 use the 2057 bulb for the parking light position.
Honda Civic models from 1986-1991 use the 168 bulb for the parking light position.
The 168 wedge base and the 2057 BAY15d bayonet base are not interchangeable, as each requires a different socket type.
The wattage difference between the two bulbs is substantial, with the 2057 drawing up to 26.9W on its primary filament compared to the 168 at 4.9W.
