Additional Notes

The PC168 bulb is the most frequently specified map light bulb for the Pontiac Grand Am, covering the 1999-2005 model years with the exception of 2002.
PC168 and PC175 are both T10 miniature wedge bulbs operating at 12V with a printed circuit board twist-lock socket, a design intended for instrument cluster applications rather than standard open sockets.
The 2002 Pontiac Grand Am uses the PC175 instead of the PC168 used in surrounding model years. Although both share the same T10 wedge form and 12V rating, the PC175 is a distinct part number and the two are not confirmed as interchangeable by these specifications.
The 168 bulb, specified for the 1993-1998 model years, is also a T10 miniature wedge type rated at 12V and 4.9W, but it lacks the printed circuit board twist-lock socket found on the PC168 and PC175.
The 562 bulb appears across the 1985-1991 model years, with the exception of 1990, making it the most common festoon-type bulb in these specifications. It is a 44mm festoon with end-cap contacts rated at 12V and 12W.
The 1990 Grand Am uses the 561 bulb rather than the 562. Both are 44mm festoon bulbs with end-cap contacts at 12V and 12W, though they carry separate ANSI designations.
The 1987 Grand Am specifies the 562 bulb specifically for vehicles equipped with sealed beam headlamps, indicating a trim or package dependency for that model year.
The 1992 Grand Am uses the 214-2, a 41mm festoon bulb with an SV8.5 base rated at 12V and 12W. Its SV8.5 base differs structurally from the end-cap contacts of the 561 and 562, making those bulbs physically incompatible with the 214-2 socket.
The 1980 Grand Am uses the 1004, a dual-filament bulb with a BAY15d bayonet base rated at 12V with a 21/5W output. Its bayonet base and dual-filament construction set it apart from every other bulb type in these specifications.
Across these specifications, four distinct socket or base types are represented: the printed circuit board twist-lock (PC168, PC175), the T10 wedge (168), the festoon end-cap (561, 562), the SV8.5 festoon base (214-2), and the BAY15d bayonet base (1004), none of which are cross-compatible with one another.
