Pontiac Ventura License Plate Bulb Size

Additional Notes

• The Pontiac Ventura uses three distinct bulb types across its model years for the license plate position: the 194, 97, and 67.
• The 194 bulb is a T10 miniature wedge type rated at 12V and 3.78W, conforming to ANSI standards for the US and Canada. Its wedge base requires no metal socket pins, as the glass envelope itself makes the electrical contact.
• The 97 bulb is a single-filament type with a BA15s bayonet base, rated at 12V and 13W. It is a variant of the widely used 1156 bulb, sharing the same base configuration but differing in wattage output.
• The 67 bulb also uses a BA15s bayonet base and is rated at 12V and 8W. It is a lower-wattage variant of the 1156 family, making it physically similar to the 97 but electrically distinct.
• The 194 is the most frequently specified bulb across the Ventura's license plate fitment data, covering the 1975-1977 model years.
• The 97 covers the 1971-1974 model years, representing the longest consecutive span of any single bulb type in these specifications.
• Because the 97 and 67 share the same BA15s bayonet base, they are physically interchangeable in terms of socket fit, but their wattage ratings differ significantly at 13W and 8W respectively, which affects light output.
• The 194 wedge base is mechanically incompatible with the BA15s bayonet socket used by the 97 and 67, meaning bulbs from the 1971-1974 and 1960-1961 Ventura are not interchangeable with those from the 1975-1977 model years.
• The 1960-1961 Ventura uses the 67 bulb, which at 8W draws notably less power than the 97 used in the 1971-1974 models, despite both belonging to the same base family.
• All three bulb types in these specifications conform to ANSI standards recognized in both the US and Canada, indicating standardized production specifications rather than proprietary or regional-only parts.
