Additional Notes

The Chevrolet Monte Carlo map light bulb specifications span the 1995-2007 model years and reference three distinct bulb types: 578, 192, and 212-2.
The 192 bulb is the most frequently specified type across these model years, appearing in the 1995-1996 and 2000-2005 Monte Carlo.
The 192 is a T10 miniature wedge bulb rated at 12V and 3W, making it a low-wattage interior lighting component by design.
The 578 and 212-2 are both festoon-style bulbs with a 41mm length and share the same 12V, 12W electrical rating, though they differ in their base type.
The 578 uses end-cap contacts, while the 212-2 uses an SV8.5 base, meaning the two festoon bulbs are not interchangeable despite their identical voltage and wattage ratings.
The 2006-2007 Monte Carlo uses the 578 festoon bulb, and the 1997-1999 model years use the 212-2 festoon bulb, reflecting a change in festoon base type across the vehicle's production history.
All three bulb types conform to ANSI standards applicable in both the United States and Canada.
The wattage difference between the 192 (3W) and the festoon types 578 and 212-2 (12W each) is significant, as substituting a higher-wattage bulb in a socket rated for lower wattage risks heat damage to the fixture.
