The Chevrolet Lumina APV brake light requires a 2057 bulb size for proper operation and visibility. Data for the specified component covers a range from 1990 through 1996.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Lumina APV uses the 2057 bulb for its brake lights across all model years from 1990 to 1996.
The 2057 is a dual-filament bulb built on a BAY15d bayonet base, operating at 12V with filament ratings of 26.9W and 8W for its high and low outputs respectively.
As an ANSI-standardized type recognized in both the US and Canada, the 2057 follows a defined specification for base geometry and electrical characteristics.
The 2057 is a brighter variant of the 1157, sharing the same BAY15d bayonet base, which means the two types are physically compatible in many sockets. However, the difference in wattage output makes them non-equivalent replacements in applications where light output levels are regulated.
The center high mount stop light on the Lumina APV uses the 561 bulb for model years 1994-1996.
The 561 is a festoon-type bulb with a 44mm length and end-cap contacts, operating at 12V and 12W. Its single-filament design reflects its dedicated use in a stop-light-only application.
Festoon bulbs such as the 561 are held in place by spring-loaded clips at each end rather than a twist or bayonet mechanism, making their fitment distinct from the bayonet-based 2057 used elsewhere on the same vehicle.
The 2057 and 561 are not interchangeable, as they differ in base type, physical form, and wattage.
