The Plymouth PB200 front turn signal bulb accommodates 3 different sizes including 1157, 1034NA, and 1157NA, while the rear turn signal bulb size options include 1157 and 198. The replacement chart covers vehicle production years spanning 1975 to 1980.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Plymouth PB200 turn signal specifications cover model years 1975-1980, spanning both front and rear positions across four distinct bulb types: 1157, 1034NA, 1157NA, and 198.
The 1157 is the most frequently specified bulb across the Plymouth PB200 turn signal positions, appearing in the front and rear turn signals for 1979-1980.
The 1157 is a dual-filament bulb rated at 12V with a 21W high filament and a 5W low filament, mounted on a BAY15d bayonet base, which allows it to serve both signaling and parking light functions within a single housing.
The 1034NA shares the same BAY15d bayonet base and 12V, 21W/5W electrical ratings as the 1157, but its glass envelope is tinted natural amber rather than clear, producing a colored output without a separate amber lens.
The 1157NA is similarly rated at 12V, 21W/5W on a BAY15d base with natural amber glass, and it was specified exclusively for the Plymouth PB200 front turn signal in 1976.
Because the 1157, 1034NA, and 1157NA share the same BAY15d base and identical voltage and wattage ratings, their physical and electrical compatibility is close, though the amber glass variants produce a different light color than the clear 1157.
The 198 is a miniature wedge bulb of the T5 form factor, rated at 12V and only 2W, making it a single-filament low-output bulb with no bayonet base and no interchangeability with the BAY15d bulb types listed above.
The 198 bulb was specified for the Plymouth PB200 rear turn signal across all six model years in the data, and it also appeared in the front turn signal position for 1975.
The front turn signal position on the Plymouth PB200 shows variation across the six model years, with three different bulb types specified: the 198 in 1975, the 1157NA in 1976, the 1034NA in 1977-1978, and the 1157 in 1979-1980.
Substituting a 198 wedge bulb for any of the BAY15d bayonet types, or vice versa, would be physically incompatible due to the fundamental difference in base design between the T5 wedge and BAY15d formats.
