Additional Notes

The 2057 bulb is the most frequently specified parking light size across the Honda Accord data, covering model years 1976-1978 and 1982-1985.
The 2057 operates at 12V with a dual-filament configuration rated at 26.9W and 8W, and it uses a BAY15d bayonet base.
As a dual-filament bulb, the 2057 supports two distinct brightness levels within a single unit, which is a common design for combined stop and tail light functions.
The 2057 is noted as a brighter variant of the 1157, meaning the two share the same BAY15d base type but are not identical in output, and substituting one for the other may produce different brightness results.
The 1990-1991 Honda Accord parking light specification calls for the 168, a single-filament miniature wedge bulb in a T10 form factor rated at 12V and 4.9W.
The low wattage of the 168 reflects its role as a low-intensity position or parking light rather than a high-output signal lamp.
The 2018 Honda Accord parking light specification uses the 7443NA, a dual-filament wedge bulb in a T20 form factor rated at 12V with filaments at 21W and 5W.
The "NA" designation in the 7443NA indicates natural amber glass, meaning the amber color is produced by the glass envelope itself rather than by an amber-tinted lens on the vehicle.
All three bulb types, the 7443NA, 168, and 2057, conform to ANSI standards applicable in both the United States and Canada.
The T10 and T20 designations on the 168 and 7443NA respectively refer to the tubular wedge base form factor, with T20 being physically larger, making the two types non-interchangeable despite both using wedge bases.
