Ford Windstar front and side marker bulbs utilize 2825, 916NA, 3156, and 2357 bulb sizes depending on location and model configuration. The replacement chart covers vehicle production years spanning 1995 to 2003 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford Windstar front side marker specifications reference four distinct bulb types across its production years: the 2825, 916NA, 3156, and 2357.
The 2825 is a miniature wedge bulb in the T10 form factor with a W2.1x9.5d base, rated at 12V and 5W. It is an ANSI-standard part recognized in both the US and Canada.
The 916NA is a T15 wedge bulb with natural amber glass, rated at 12V and 18W. Its amber tint is built into the glass itself rather than applied through a lens or coating.
The 3156 is a single-filament T25 wedge bulb rated at 12V and 27W, making it the highest-wattage bulb among those listed in the front side marker positions.
The 2357 uses a BAY15d bayonet base and carries dual filaments rated at 26.9W and 8W on a 12V circuit. It is described as a brighter variant of the 1157 bulb.
The Ford Windstar (1999-2003) uses the 2825 in the standard front side marker position, while the 1995-1998 models use the 916NA in that same position, indicating a bulb type change between the 1998 and 1999 model years.
The bumper-mounted front side marker position on the 2001-2002 Windstar takes the 3156, whereas the 1999, 2002, and 2003 models use the 2825 in that same bumper location, meaning the 3156 and 2825 are not interchangeable despite both being wedge-type bulbs.
The 1995-1998 Windstar uses the 2357 in the bumper front side marker position. Because the 2357 has a BAY15d bayonet base, it is physically incompatible with the wedge-base sockets used by the 2825, 916NA, and 3156.
The shift from the 916NA to the 2825 between the 1998 and 1999 model years also represents a significant wattage reduction, from 18W down to 5W, in the standard front side marker position.
All four bulb types listed in the specifications conform to ANSI standards applicable in both the US and Canada.
