Lexus LX450 front and rear turn signal bulbs use a 1156 bulb size for both locations. The replacement chart covers 1996 to 1997 model 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 1156 bulb is the sole bulb type specified for the Lexus LX450 across both front and rear turn signal positions for the 1996-1997 model years.
The 1156 is a single-filament bulb, meaning it is dedicated to one lighting function rather than serving dual purposes such as combined stop and tail operation.
It operates on a 12-volt electrical system at 21 watts, which is consistent with standard automotive incandescent turn signal applications.
The 1156 uses a BA15s bayonet base, a single-contact mount where the bulb is inserted and rotated to lock into the socket.
The BA15s designation distinguishes it from the visually similar BA15d base, which has two contacts. The two bases are not interchangeable despite their physical resemblance.
The 1156 conforms to ANSI standards applicable in the United States and Canada, indicating it meets defined performance and dimensional criteria for those markets.
The uniform use of the 1156 across all four turn signal positions on the LX450 means a single bulb type serves the entire turn signal system on the vehicle.
