The Iveco Z450T front and rear turn signal bulbs both utilize a 1156 size. Replacement specifications for this vehicle span a 1980 to 1987 production chart.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Iveco Z450T uses the 1156 bulb type across all listed model years for both front and rear turn signals.
The 1156 is an ANSI-standardized bulb recognized in the United States and Canada, operating at 12 volts and 21 watts.
As a single-filament bulb, the 1156 is dedicated to one lighting function, which in this context is the turn signal circuit.
The 1156 uses a BA15s bayonet base, a single-contact mount where the bulb locks into its socket with a twist.
The Z450T front and rear turn signals share the same 1156 bulb specification across the 1980-1987 model year range.
The BA15s base is not interchangeable with the BA15d base, which is a dual-contact variant of the same bayonet mount family, despite the physical similarity between the two.
