Suzuki Motorcycle LT250R QuadRacer headlight bulb size specifications indicate both high beam and low beam applications utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 1985 to 1992, detailing bulb specifications across this 8-year range.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki Motorcycle LT250R QuadRacer uses the 9003 bulb size for both the high beam and low beam headlight positions across the 1985-1992 model years.
The 9003 is an ANSI-standardized bulb type recognized in the United States and Canada, making it a widely available halogen format within North American markets.
As a dual-filament bulb, the 9003 houses two separate filaments within a single housing, which allows it to serve both high and low beam functions from one unit.
The 9003 operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type determines physical fitment and is not interchangeable with bulbs that use different base configurations.
Because the same bulb type is specified for both the high beam and low beam positions, a single 9003 bulb serves the full headlight function on this vehicle rather than requiring two separate bulb types.
