The Dodge A100 Pickup front turn signal requires a 1156 bulb size, while rear turn signals use either 199 or 1156 bulb sizes. The replacement chart covers 1967 to 1968 model years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1156 bulb is an ANSI-standard single-filament type rated at 12V and 21W, fitted with a BA15s bayonet base. It is recognized across both the United States and Canada as a standardized automotive bulb.
The BA15s bayonet base designation indicates a single-contact base with a 15mm barrel, which is a widely used base type in automotive lighting applications.
The 199 bulb shares the same 12V, 21W rating and BA15s bayonet base as the 1156, and is classified as a variant of it under the ANSI standard.
For the Dodge A100 Pickup, the 1156 bulb serves as the front turn signal for both the 1967 and 1968 model years.
The rear turn signal position shows a bulb change between model years. The 1967 model uses the 1156, while the 1968 model uses the 199.
Although the 1156 and 199 are closely related variants sharing the same base type and electrical ratings, their use in different positions on the 1968 model suggests they are not treated as interchangeable in that application.
