The Lexus LX450 tail light requires a 1157 bulb size for proper installation and function within the rear lighting assembly. Data for 1157 bulbs covers the 1996 to 1997 range of production for the specified vehicle.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1157 bulb is the sole bulb type listed across all outer tail light positions for the Lexus LX450, appearing in both the 1996 and 1997 model years.
The 1157 is a dual-filament bulb, meaning it serves two lighting functions within a single unit, typically combining stop and tail light operation through its two separate filaments rated at 21W and 5W respectively.
The 1157 operates on a 12-volt electrical system, which is standard for passenger vehicles of this era.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design where the two pins are positioned at different heights to ensure the bulb is inserted in the correct orientation, preventing filament misalignment.
The 1157 conforms to ANSI standards as applicable in the United States and Canada, indicating it meets a defined set of dimensional and performance criteria for those markets.
The 1996 outer tail light specification carries a production date qualifier of "From 11/1995," indicating that this bulb size applies only to vehicles produced from November 1995 onward within that model year.
