The UD 3000 uses 1156 bulb size for both front and rear turn signal applications. The replacement chart covers vehicle production spanning 1995 to 1998.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1156 is the sole bulb type specified for the UD 3000 across all listed turn signal positions and model years.
The 1156 follows the ANSI standard, meaning it conforms to a defined North American specification recognized in both the United States and Canada.
It is a single-filament bulb, which means it serves one lighting function only, as opposed to dual-filament types that handle two functions such as braking and signaling from a single unit.
The 1156 uses a BA15s bayonet base, a single-contact mount where the bulb is inserted and twisted to lock into place.
The bulb operates at 12 volts and draws 21 watts, consistent with standard automotive electrical systems.
The same 1156 bulb size is specified for both the front and rear turn signals across the 1995-1998 model years, indicating uniform fitment throughout the vehicle.
Because the 1156 is a single-filament type, it is not interchangeable with the 1157, a visually similar dual-filament bulb that shares a comparable but mechanically distinct BA15d base with two contact pins rather than one.
