Toyota Cressida Parking Light Bulb Size

Additional Notes

• The Toyota Cressida parking light specifications reference three distinct bulb types across its production run: the 194, 168, and 1157, along with the natural amber variants 1157NA and 1034NA.
• The 194 and 168 are both T10 miniature wedge bulbs operating at 12V, though they differ in wattage. The 194 draws 3.78W, while the 168 draws 4.9W. Despite sharing the same base type, these two bulbs are not rated identically and are not direct substitutes for one another.
• The 1157 is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with a 21W high filament and a 5W low filament. Its dual-filament design distinguishes it functionally from the single-filament T10 wedge types used in other model years.
• The 1157NA carries the same electrical ratings and BAY15d bayonet base as the standard 1157, but its glass envelope is natural amber rather than clear. This coloring is built into the glass itself rather than applied as a coating.
• The 1034NA shares the BAY15d bayonet base and natural amber glass of the 1157NA and is described as a variant of the 1157. It is rated at 12V, 21W/5W, making its electrical characteristics equivalent to the 1157 family.
• The 1979 Toyota Cressida uses the 1157NA, while the 1978 model uses the 1034NA. Both bulbs share the BAY15d base and natural amber glass, but they are distinct part numbers and should not be assumed to be interchangeable without confirming fitment.
• The 194 bulb appears across the 1982-1984 and 1987-1988 model years, while the 168 is specified for 1989-1990 and 1992. Although both are T10 wedge types, substituting one for the other would result in a wattage mismatch relative to the original specification.
• All bulb types listed in these specifications conform to ANSI standards applicable in the United States and Canada, indicating standardized sizing and base configurations across the referenced part numbers.
