The Iveco EuroTurbo 435T uses 1156 bulb size for both front and rear turn signal applications. Replacement chart data spans 1987 to 1990 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1156 is a single-filament bulb with a BA15s bayonet base, rated at 12 volts and 21 watts under the ANSI standard used in the United States and Canada.
The BA15s bayonet base features a single contact pin, which distinguishes it from the dual-pin BA15d base found on double-filament variants. This distinction is relevant when sourcing a replacement, as the two base types are not interchangeable.
The Iveco EuroTurbo 435T uses the 1156 bulb across both its front and rear turn signal positions for the 1987-1990 model years.
Because the same bulb type is specified for both the front and rear turn signal positions, a single 1156 bulb serves both locations without substitution or adaptation.
