The Chevrolet Lumina APV tail light requires a bulb size of 2057 for the rear lighting assembly. Data for the specified component covers the range from 1995 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 two distinct bulb types across its tail light assembly for the 1990-1996 model years: the 2057 in the lower position and the 194 in the upper position.
The 2057 is a dual-filament bulb, meaning it serves two separate lighting functions within a single unit, typically stop and tail light operation, through independent filaments rated at 26.9W and 8W respectively.
The 2057 uses a BAY15d bayonet base, which is an offset-pin base design. The offset pins prevent incorrect installation by ensuring the bulb can only be seated in one orientation, aligning each filament with its intended circuit.
The 2057 is described as a brighter variant of the 1157. While the two share the same BAY15d base and are physically interchangeable in many sockets, the 2057 produces greater light output on its high-filament circuit.
The 194 is a T10 miniature wedge bulb, a single-filament type that relies on its wedge-shaped base to make electrical contact without a separate metal base component.
At 3.78W, the 194 operates at a significantly lower wattage than the 2057, reflecting its role in a lower-intensity lighting function such as a marker or indicator position within the upper tail light assembly.
Both the 2057 and 194 conform to ANSI standards recognized in the United States and Canada, indicating standardized electrical and physical specifications across manufacturers.
Both bulb types operate on a 12V system, consistent with standard automotive electrical architecture.
