Lexus LX450 brake bulbs utilize a 1157 size for both inner and outer brake light applications. The replacement chart covers vehicle production spanning 1996 to 1997.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1157 is an ANSI-standard dual-filament bulb rated at 12 volts with a 21W/5W power draw, meaning it carries one filament for the higher-intensity brake function and a second for a lower-intensity running light function within the same housing.
The 1157 uses a BAY15d bayonet base, a two-pin offset base design that prevents incorrect installation by ensuring the bulb can only be seated in one orientation.
The Lexus LX450 uses the 1157 bulb across both the standard brake and outer brake positions for the 1996-1997 model years.
The 1996 outer brake position carries a production date qualifier, specifying fitment from November 1995 onward, which corresponds to vehicles built partway through the 1996 production run rather than from its start.
Because the same 1157 bulb size is specified for both the standard brake and outer brake positions across both model years, the LX450 does not require different bulb types between those two positions.
