The Mercury Sable side marker utilizes bulb sizes 194 and 168 for illumination purposes across various vehicle generations. Data for the specified lighting components covers the range from 1996 to 2009.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The front side marker position on the Mercury Sable uses the 194 bulb across the 1986-2005 model years, making it the most consistently specified bulb in these listings. It is an ANSI-standard miniature wedge type in the T10 form factor, rated at 12V and 3.78W.
For the 2008-2009 Mercury Sable, the front side marker specification shifts to the 194NA bulb. This variant shares the same T10 wedge form factor, 12V supply voltage, and 3.78W power rating as the standard 194, but its glass envelope is tinted natural amber rather than clear.
The natural amber tint of the 194NA produces a colored output from the bulb itself, without relying on a tinted lens to generate the amber appearance required for side marker lighting.
Although the 194 and 194NA share identical electrical and physical characteristics, substituting a clear 194 for a 194NA in a housing designed around the amber-tinted variant may alter the color output at the lamp, depending on lens color.
The rear side marker on the Mercury Sable uses the 194 bulb for the 1986-1995 model years, placing the same T10 wedge type at both front and rear positions during that period.
From 1996-1999, the rear side marker specification on the Sable changes to the 168 bulb. Like the 194, the 168 is an ANSI-standard T10 miniature wedge bulb operating at 12V, but its wattage rating is 4.9W rather than 3.78W.
The higher wattage of the 168 relative to the 194 means the two bulbs draw different amounts of current despite sharing the same T10 physical format. This distinction is relevant when considering one as a substitute for the other.
The T10 wedge base is a tool-free, push-in socket type, meaning all three bulbs in these specifications, the 194, 194NA, and 168, install and remove without a separate bulb holder or locking mechanism.
All bulbs listed across both the front and rear side marker positions conform to ANSI standards applicable in both the United States and Canada, indicating a shared regulatory baseline for the bulb specifications used throughout the Sable's production run.
The rear side marker position carries no specification entries beyond the 1999 model year in these listings, while the front side marker position extends through 2009, reflecting a difference in the model years covered between the two positions.
