Additional Notes

The Chevrolet Suburban license plate bulb specifications cover model years 1950 through 2023, with four distinct bulb types appearing across that span: the 63, 67, 89, 97, 194, and 12961.
The 194 and 12961 are both T10 miniature wedge bulbs, sharing the same physical form factor. However, they are not identical in wattage: the 194 draws 3.78W while the 12961 draws 5W, and the 12961 uses a W2.1x9.5d base under a Philips part number rather than a generic ANSI designation.
The 194 is the most frequently specified bulb across the Suburban's history, appearing in model years 1992-2006 and 2021-2023, though the 2022 model year is absent from the specifications.
The Chevrolet Suburban (2007-2020) uses the 12961 exclusively for the license plate position, making it the bulb associated with that generation's fitment.
The 67, 89, and 97 bulbs all share the same BA15s bayonet base, which means they are physically similar in mounting style, but their wattage ratings differ: the 67 is rated at 8W, while both the 89 and 97 are rated at 13W.
Despite sharing a base type, the 67, 89, and 97 are not interchangeable without consideration of wattage differences, as substituting a higher-wattage bulb in a socket rated for a lower one can affect socket integrity over time.
The bulb 63 uses a BA9s base, which is a smaller bayonet fitting distinct from the BA15s used by the 67, 89, and 97, making it physically incompatible with sockets designed for those types.
The 63 is the lowest-wattage bulb in these specifications at 0.63W, and it appears only in the earliest model years on record, specifically 1950-1955.
The 97 bulb appears only in model years 1974-1979, and at 13W it carries the same wattage as the 89 but is classified as a separate ANSI variant of the 1156 family.
The 67 is described as a lower-wattage variant of the 1156 bulb family, and it appears across non-consecutive groups of model years: 1956-1957, 1960-1963, and 1980-1991.
