The Oldsmobile LSS uses a 9005 bulb size for high beam headlights and a 9006 bulb size for low beam headlights. The replacement chart covers vehicle production years from 1996 to 1999 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 Oldsmobile LSS uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across the 1996-1999 model years.
Both the 9005 and 9006 are single-filament halogen bulbs that conform to ANSI standards recognized in the United States and Canada.
The 9005 high beam bulb operates at 12 volts and draws 65 watts, while the 9006 low beam bulb operates at 12 volts and draws 55 watts.
The 9005 uses a P20d base and the 9006 uses a P22d base. These two base types are physically distinct, meaning the bulbs are not interchangeable despite their otherwise similar construction.
Single-filament bulbs contain one electrical filament, which means each bulb serves only one lighting function. The LSS therefore requires separate bulbs for high and low beam operation rather than a dual-filament unit handling both.
