Buick Electra License Plate Bulb Size

Additional Notes

• The 194 bulb is the most frequently specified license plate bulb across the Buick Electra's model history, covering the 1972-1979 and 1981-1986 model years, as well as 1990.
• The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, making it one of the lower-wattage options found in these specifications.
• The 168 bulb shares the same T10 miniature wedge form factor as the 194 but draws more power at 4.9W, and it was specified for the Buick Electra in 1977 and 1980.
• Because the 194 and 168 share the same T10 wedge base, physical fitment between the two is possible, though their wattage ratings differ and they are not designated as interchangeable in these specifications.
• The 97 bulb uses a BA15s bayonet base and is rated at 12V and 13W, representing a significantly higher wattage than either T10 wedge type listed above.
• The 97 was specified for the Buick Electra across the 1965-1971 model years, and it is described as a variant of the 1156 bulb family.
• The 1155 bulb also uses a BA15s bayonet base and is a variant of the 1156 family, but at 21W it carries the highest wattage rating of any bulb in these specifications. It was specified solely for the 1964 model year.
• The 67 bulb likewise uses a BA15s bayonet base and is described as a lower-wattage variant of the 1156, rated at 8W. It was specified for the Buick Electra across the 1959-1963 model years.
• The 97, 1155, and 67 bulbs all share the BA15s bayonet base, meaning they are physically similar in mounting style, yet their wattage ratings of 13W, 21W, and 8W respectively indicate they are distinct and non-interchangeable bulbs.
• All five bulb types listed in these specifications conform to ANSI standards applicable in both the United States and Canada, and all operate on a 12V electrical system.
