The Ford Aspire side marker requires a unique 12961 bulb size for proper installation and function. Data for the specific component covers the range from 1995 to 1997.
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 sole bulb type specified across all side marker positions on the Ford Aspire, covering both front and rear applications for the 1994-1997 model years.
The 194 is classified as a miniature wedge bulb, designated T10 in the international bulb sizing system, where "T" refers to the tubular shape and "10" indicates the width in eighths of an inch.
The 194 operates at 12 volts with a power draw of 3.78 watts, placing it in the low-wattage range typical of parking and marker lamp applications.
The 194 carries ANSI standardization recognized in both the United States and Canada, meaning the bulb conforms to a defined set of electrical and physical tolerances shared across manufacturers.
The wedge base design of the T10 format means the bulb is held in its socket by the tension of the glass envelope itself rather than by a separate metal base, which is a common trait of low-current marker lamps.
Because the Ford Aspire uses the same 194 bulb for both front and rear side markers across all four model years, the front and rear positions are interchangeable with respect to bulb fitment.
