The Ford L8513 front side marker uses a 1895 bulb size, while rear side marker applications require either 194 or 168 bulb sizes. The replacement chart covers 1996 to 1998 vehicle 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 L8513 uses two distinct bulb types for front and rear side markers across the 1996-1998 model years: the 1895 for all front positions and either the 194 or 168 for rear positions.
The 1895 bulb is a T5 miniature wedge type rated at 12V and 0.9W, conforming to ANSI standards for the US and Canada.
The 194 and 168 bulbs are both T10 miniature wedge types operating at 12V, though they differ in wattage: the 194 draws 3.78W while the 168 draws 4.9W.
All three bulb types in these specifications follow ANSI standards applicable to both the US and Canadian markets.
The front side marker position on the Ford L8513 uses the 1895 bulb consistently across all three model years covered.
The rear side marker position on the Ford L8513 (1997) takes a 168 bulb, while the 1996 and 1998 model years use the 194 bulb in that same position.
Although the 194 and 168 share the same T10 wedge base form factor, their wattage ratings differ, and substituting one for the other in the rear side marker position would not replicate the original electrical draw for the 1997 model year.
