Additional Notes

The Toyota MR2 license plate bulb specifications cover model years 1985-1995, with two distinct bulb types used across that span: the 168 and the 89.
The 168 bulb is a T10 miniature wedge type rated at 12V and 4.9W. Its wedge base design means it is held in place by tension from the socket rather than by a locking mechanism.
The 89 bulb uses a BA15s single-contact bayonet base and is rated at 12V and 13W. The bayonet mount is a twist-and-lock style fitting, which is physically incompatible with the wedge socket used by the 168.
Both bulb types conform to ANSI standards applicable in the United States and Canada.
The Toyota MR2 (1993-1995) takes the 168 bulb for the license plate position, while model years 1985-1992 use the 89 bulb. These two bulb types are not interchangeable due to their different base designs.
The 89 bulb is described as a lower wattage variant of the 1156. At 13W, it draws notably more power than the 4.9W 168, meaning the two bulbs also differ in electrical load despite serving the same lighting position across different model years.
The 1992 model year marks the transition point between the 89 and 168 bulb types, with 1992 still using the 89 before the specification shifted to the 168 for 1993 onward.
