Dodge D250 front and rear side marker bulbs utilize a 194 bulb size for replacement applications. The replacement chart covers vehicle production spanning 1981 to 1993.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge D250 uses the 194 bulb for both front and rear side marker positions across all listed model years.
The 194 is an ANSI-standardized bulb recognized across the United States and Canada, meaning it conforms to a defined set of electrical and physical specifications shared by multiple manufacturers.
The 194 bulb is a T10 miniature wedge type, which refers to its wedge-shaped base that seats directly into a socket without a separate metal base or pins.
The 194 operates at 12 volts and draws 3.78 watts, placing it in the low-wattage category typical of marker and courtesy lighting applications.
The front side marker position on the Dodge D250 uses the 194 bulb across the 1981-1993 model years.
The rear side marker position on the Dodge D250 uses the 194 bulb across the 1986-1991 model years.
Because both the front and rear side marker positions share the same 194 bulb specification, a single bulb type serves both locations on model years where both positions are listed.
The T10 wedge form factor is a widely used base type in automotive lighting, and aftermarket 194 bulbs from various manufacturers are generally interchangeable as long as they conform to the same ANSI 194 standard for voltage and wattage.
