The Oldsmobile Aurora side marker utilizes a 194 bulb size for the lighting components located on the exterior of the vehicle body. Data for the specific bulb requirements covers the range from 1995 to 1999.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 194 bulb is the most frequently specified size across the Oldsmobile Aurora's side marker positions, appearing in the front side marker for all listed model years and in the rear side marker for 1995-1999.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, conforming to ANSI standards applicable in both the United States and Canada.
The 3057 is a T25 dual-filament wedge bulb rated at 12V with a 27W main filament and a 7W secondary filament, also conforming to ANSI standards for the US and Canadian markets.
The dual-filament design of the 3057 means it is electrically and physically distinct from the single-filament 194, making the two bulbs non-interchangeable despite both using a wedge base format.
The Oldsmobile Aurora (2001-2003) uses the 3057 in the rear side marker position, a specification that differs from earlier model years in that same position.
The front side marker position uses the 194 across all listed years from 1996-2003, indicating a consistent fitment requirement for that position throughout the Aurora's production span covered by these specifications.
The wattage difference between the 194 (3.78W) and the 3057 (27W/7W) is substantial, reflecting their different functional roles within the vehicle's lighting system.
Both the 194 and 3057 operate on a 12V electrical system, which is standard for passenger vehicles of this type and era.
