Oldsmobile Achieva Map Light Bulb Size

The Oldsmobile Achieva map light requires bulb sizes 168, 194, and 214-2 depending on the specific vehicle configuration. Data for the bulb sizes covers the range from 1992 to 1998.

Additional Notes

The Oldsmobile Achieva map light draws from three distinct bulb types across its production run: the 168, the 194, and the 214-2.
The 168 and 194 are both T10 miniature wedge bulbs operating at 12V, sharing the same physical base type and socket format.
Despite their shared T10 wedge form, the 168 and 194 are not identical. The 168 is rated at 4.9W while the 194 is rated at 3.78W, meaning they differ in power draw and light output.
The 214-2 is a festoon bulb with an SV8.5 base and a 41mm length, operating at 12V and 12W. Its form factor is entirely different from the T10 wedge types used in other model years.
All three bulb types conform to ANSI standards applicable in both the United States and Canada.
The Oldsmobile Achieva (1996) uses the 214-2 festoon bulb for the map light, which is physically incompatible with the wedge-style sockets found in the surrounding model years.
The 168 bulb is specified for the 1993-1995 and 1997-1998 model years, making it the most frequently occurring map light bulb across the Achieva's production span.
The 1992 model year uses the 194 bulb, which, while sharing the T10 wedge base with the 168, should not be substituted interchangeably without accounting for the wattage difference.
