Plymouth Barracuda front and rear side marker bulbs utilized 168, 194, and 1895 bulb sizes across model generations. The replacement chart covers 1968 through 1974 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 Plymouth Barracuda side marker bulb specifications cover model years 1968-1974, spanning both front and rear positions across three distinct bulb sizes: 168, 194, and 1895.
All three bulb types referenced in these specifications are ANSI-standardized miniature wedge bulbs rated at 12 volts, making them compatible with the standard 12V electrical systems used in automotive applications of that era.
The 1895 bulb is a T5 miniature wedge type rated at 0.9W, and it is specified for both the front and rear side marker positions on the Plymouth Barracuda for model years 1968-1970.
The 194 bulb is a T10 miniature wedge type rated at 3.78W, specified for both front and rear side marker positions on the Barracuda for model years 1971-1972.
The 168 bulb is also a T10 miniature wedge type, rated at 4.9W, and is specified for both front and rear side marker positions for model years 1973-1974.
The front and rear side marker positions share identical bulb size requirements across all model years covered in these specifications, meaning no distinction exists between front and rear fitment for any given year.
Although the 168 and 194 bulbs share the same T10 wedge base form factor, their wattage ratings differ at 4.9W and 3.78W respectively, and they are not listed as interchangeable within these specifications.
The T5 wedge base of the 1895 bulb is physically smaller than the T10 wedge base of the 168 and 194 bulbs, which means the 1895 is not a direct physical substitute for either of the T10 types used in later model years.
