Toyota Celica Parking Light Bulb Size

Additional Notes

• The Toyota Celica parking light specifications span the 1971-2002 model years, with five distinct bulb types used across that range: the 168, 194, 1157, 2057, 67, and 97.
• The 1157 is the most frequently specified bulb across the Toyota Celica parking light fitments, appearing in the 1971-1972, 1974-1981, 1987-1988, 1990-1992, 1994, and 1998 model years. It is a dual-filament bulb with a BAY15d bayonet base rated at 12V and 21W/5W, where the two wattage values correspond to its high and low filaments respectively.
• The 2057, specified for the 1993 model year, shares the same BAY15d bayonet base as the 1157 but operates at higher wattages of 26.9W/8W, making it a physically interchangeable yet electrically distinct variant. Substituting one for the other without accounting for the wattage difference may affect circuit load and light output.
• The 67 bulb, used in the 1982-1986 model years, is a single-filament type with a BA15s bayonet base rated at 12V and 8W. The BA15s base is not interchangeable with the BAY15d base used by the 1157 and 2057, as the two bayonet types differ in pin alignment.
• The 97 bulb, specified solely for the 1973 model year, is also a single-filament type with a BA15s bayonet base, rated at 12V and 13W. It is a variant of the 1156 family and shares the same base type as the 67 but draws more wattage.
• The 194 and 168 are both T10 miniature wedge bulbs operating at 12V, with the 194 rated at 3.78W and the 168 rated at 4.9W. While both share the same wedge base form factor, the wattage difference means they are not electrically identical despite their physical similarity.
• The 194 is specified for the Toyota Celica in the 1995-1997 and 1999 model years, while the 168 applies to the 2000-2002 model years. The shift between these two T10 wedge types at the 1999-2000 boundary reflects a change in the parking light circuit's wattage requirement.
• All six bulb types in these specifications conform to ANSI standards applicable in the United States and Canada, indicating that the sizing designations follow a standardized North American classification system rather than proprietary or regional equivalents.
