Additional Notes

The Oldsmobile Achieva dome light specifications span the 1992-1998 model years, with four distinct bulb types used across that period: the 562, 168, 214-2, and 192.
All four bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada.
The 168 bulb is the most frequently specified type across the Achieva's model years, appearing in the 1993-1994 and 1997 model years. It is a T10 miniature wedge bulb rated at 12V and 4.9W.
The miniature wedge form factor, shared by both the 168 and 192 bulbs, uses a plastic wedge base that is held in place by socket tension rather than a locking mechanism, making the two physically similar in installation style.
Although the 168 and 192 are both T10 miniature wedge bulbs operating at 12V, their wattage ratings differ. The 168 draws 4.9W while the 192 draws 3W, meaning the two are not electrically interchangeable despite their shared form factor.
The 214-2 festoon bulb, specified for the 1995-1996 Achieva, measures 41mm in length and uses an SV8.5 base with end-cap contacts. It is rated at 12V and 12W.
The 562 festoon bulb, specified for the 1998 Achieva, is rated at 12V and 12W, matching the 214-2 in voltage and wattage. However, the 562 measures 44mm in length compared to the 41mm of the 214-2, making the two physically non-interchangeable despite identical electrical ratings.
Festoon bulbs, such as the 562 and 214-2, are cylindrical lamps that make contact at both ends. The length of a festoon bulb is a critical fitment factor, as a bulb that is too short or too long will not seat properly in the socket.
The 1992 Oldsmobile Achieva uses the 192 bulb, which at 3W is the lowest-wattage type in these specifications. This makes it distinct from all other model years in the Achieva dome light lineup.
The Achieva's dome light bulb type changed multiple times across its production run, with no single bulb type used in consecutive model years spanning more than three years, reflecting variation in supplier or design choices across the vehicle's lifecycle.
