Plymouth Cuda front and rear side marker bulbs utilized 168, 194, or 1895 size bulbs depending on production specifications. The replacement chart covers 1970 through 1974 model years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Plymouth Cuda uses three distinct bulb sizes across its side marker positions: 168, 194, and 1895, all of which conform to ANSI standards recognized in both the United States and Canada.
All three bulb types are miniature wedge-base designs, meaning they use a wedgeless plastic base that seats directly into a socket without a separate metal base or bayonet pins.
The 168 and 194 bulbs share the T10 wedge form factor, which refers to a tubular glass envelope roughly 10 millimeters wide. Despite this shared form factor, the two bulbs are not interchangeable due to differing wattage ratings.
The 1895 bulb uses a T5 form factor, which is a narrower tubular envelope than the T10. This makes it physically incompatible with sockets designed for the 168 or 194 bulbs.
The 168 bulb operates at 12V and 4.9W, making it the highest-wattage option among the three types listed in these specifications.
The 194 bulb operates at 12V and 3.78W, placing it between the 168 and 1895 in terms of power draw despite sharing the same T10 form factor as the 168.
The 1895 bulb operates at 12V and 0.9W, the lowest wattage of the three types. Its significantly reduced power draw reflects its smaller T5 envelope.
For the Plymouth Cuda, the 1973-1974 model years use the 168 bulb in both the front and rear side marker positions, while the 1971-1972 model years use the 194 bulb in both positions.
The 1970 Plymouth Cuda uses the 1895 bulb for both front and rear side marker positions, which differs in both form factor and wattage from the bulbs used in all subsequent model years covered by these specifications.
Because the front and rear side marker positions share the same bulb size within each model year, a single bulb type services both locations on any given year of the Cuda covered here.
