Additional Notes

The Chevrolet Chevelle license plate bulb specifications cover model years 1964-1973 and reference three distinct ANSI-standard bulb types: the 67, 97, and 1155.
All three bulb types share the same BA15s single-contact bayonet base and operate at 12 volts, making the base format consistent across the entire ten-year span of these specifications.
The bulb 67 is the most frequently specified type, appearing across six model years: 1964-1965 and 1968-1971. It is a single-filament bulb rated at 8W, the lowest wattage among the three types listed.
The 97 bulb is specified for the 1972-1973 Chevrolet Chevelle and is described as a variant of the 1156. It carries a 13W rating, placing it between the 67 and 1155 in terms of power draw.
The 1155 bulb applies to the 1966-1967 model years and is rated at 21W, the highest wattage of the three types. It is also described as a variant of the 1156.
Because the 67, 97, and 1155 are all variants of the 1156 with a shared BA15s base, their physical mounting interface is identical, though their wattage ratings differ substantially across 8W, 13W, and 21W respectively.
The wattage difference between the 67 and 1155 is significant at 13W, which reflects a meaningful difference in light output and current draw despite the shared base type.
All three bulb types conform to ANSI standards recognized in both the United States and Canada, indicating standardized performance and dimensional specifications within those markets.
