Ford Escort front and rear side marker bulbs utilize 194, 3157, 1157, and 168 bulb sizes depending on location and model generation. The replacement chart covers 1986 through 2003 production years 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 Escort uses the 194 bulb more than any other type across its side marker specifications. It is an ANSI-standard miniature wedge bulb in the T10 form factor, rated at 12V and 3.78W, and it appears in both front and rear side marker positions across multiple model years.
The 3157 is the second most frequently specified bulb in these listings. It is a dual-filament T25 wedge bulb rated at 12V with a 27W high filament and a 7W low filament, and it serves as the rear side marker for the Ford Escort from 1997-2003.
The front side marker on the Ford Escort uses the 194 bulb consistently from 1997-2003, indicating a stable fitment across that production span.
The 916 bulb, a single-filament T15 wedge rated at 12V and 18W, is specified for both front and rear side marker positions in the 1990-1991 model years, and for the rear side marker in 1988-1989.
The 2357 bulb is specified for both the front and rear side marker positions on the 1987 Ford Escort. It uses a BAY15d bayonet base and is a dual-filament type rated at 12V, 26.9W/8W, functioning as a brighter variant of the 1157.
The 1157 and 2357 bulbs share the same BAY15d bayonet base, but they are not identical in output. The 2357 operates at 26.9W/8W while the 1157 operates at 21W/5W, making them physically interchangeable in base type but different in brightness.
The 194 and 168 bulbs both occupy the T10 wedge form factor, yet they differ in wattage. The 194 is rated at 3.78W while the 168 is rated at 4.9W. The 168 is specified only for the 1993 rear side marker position.
The front side marker specification for the 1992 Ford Escort calls for the 1157, a BAY15d dual-filament bayonet bulb, while the rear side marker for the same year uses the 194 wedge bulb, indicating that the two positions require physically distinct bulb types for that model year.
The 1993 Ford Escort front side marker uses the 3157, a dual-filament wedge, while the rear uses the 168, a single-filament T10 wedge, meaning the front and rear positions are not interchangeable for that year.
All bulb types listed across these specifications conform to ANSI standards recognized in both the United States and Canada, and all are rated for 12V electrical systems.
