The Dodge A108 Van uses 1156 and 199 bulb sizes for both front and rear turn signal applications, with these specifications representing the standard replacements across the model line. The replacement chart covers 1967 to 1970 production years and documents the bulb size requirements for turn signal functions throughout this period.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Dodge A108 Van uses two bulb types across its front and rear turn signal positions: the 1156 and the 199, both conforming to ANSI standards applicable in the US and Canada.
Both the 1156 and 199 are single-filament bulbs rated at 12V and 21W, sharing identical electrical characteristics.
Both bulb types use the BA15s bayonet base, a single-contact base with a 15mm collar width, which physically allows either bulb to seat in the same socket type.
The 199 is classified as a variant of the 1156, meaning the two share the same base type, voltage, and wattage, though they are catalogued under distinct ANSI part numbers.
For the front turn signal on the Dodge A108 Van, the 1156 was specified for 1969-1970, while the 199 was specified for 1967-1968.
For the rear turn signal, the 1156 was specified for 1967 and again for 1969-1970, while the 199 was specified for 1968 only.
The shared BA15s base between the 1156 and 199 means physical fitment is possible in either socket, though the specifications assign each bulb to distinct model years and positions.
