Additional Notes

The Toyota Supra license plate bulb specifications span the 1986-1998 model years, with three distinct bulb types used across that period: the 89, 168, and 12961.
The bulb 89 is the most frequently specified type, covering the 1986-1993 model years. It is an ANSI-standard single-filament bulb with a BA15s bayonet base, rated at 12V and 13W, and is considered a lower wattage variant of the 1156.
The BA15s bayonet base of the 89 bulb is mechanically distinct from the wedge-style base found on the 168 and 12961 bulbs, meaning these types are not interchangeable with one another.
The 168 bulb is specified for the 1994-1996 Toyota Supra. It follows the ANSI standard applicable in the US and Canada, uses a T10 miniature wedge form factor, and is rated at 12V and 4.9W.
The 12961 is a Philips part number designation for a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. It is specified for the 1997-1998 model years.
Both the 168 and 12961 share the T10 wedge form factor, though the 12961 carries a wattage of 5W versus the 4.9W rating of the 168. The 12961 is identified by a Philips-specific part number rather than an ANSI designation.
The shift from the 13W bayonet-base 89 bulb to the sub-5W wedge-base bulbs in 1994 represents a substantial reduction in wattage for the license plate position across the Supra's production run.
