The Jeep Tornado front and rear turn signal bulbs both utilize a 1034 size bulb for proper operation. The replacement chart covers 1962 through 1965 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 1034 bulb is the sole bulb type specified for the Jeep Tornado across both front and rear turn signal positions for the 1962-1965 model years.
The 1034 is a dual-filament bulb, meaning it serves two lighting functions within a single unit, typically combining a brighter filament for signaling with a dimmer filament for running or parking light duty.
It operates on a 12-volt electrical system and carries a 21/5W power rating, where 21 watts corresponds to the high-intensity filament and 5 watts to the low-intensity filament.
The 1034 uses a BAY15d bayonet base, a two-pin base type in which the two pins are offset at different heights to ensure correct polarity orientation during installation.
The 1034 is classified as an ANSI standard bulb recognized in both the United States and Canada.
The 1034 is described as a variant of the 1157, a widely used automotive bulb. While the two share the same BAY15d base and dual-filament configuration, they are not identical and are not confirmed as interchangeable within these specifications.
