The Suzuki Motorcycle TU250X uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years spanning 2009 to 2019 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 9003 is the sole bulb type specified across all listed model years of the Suzuki Motorcycle TU250X, serving both the high beam and low beam headlight positions.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
The 9003 operates on a 12V electrical system and uses a P43t base, which is a bayonet-style fitting with a 43mm collar.
The 9003 designation follows the ANSI standard used in the United States and Canada, making it distinct from the H4 bulb used in other markets, despite the two types sharing nearly identical electrical and physical characteristics.
Because the 9003 handles both beam functions within one bulb, the TU250X does not use separate bulbs for high and low beam operation across the 2009 and 2012-2019 model years covered in the specifications.
The H4 and 9003 types are functionally interchangeable in many applications due to their shared filament configuration and base design, though the 9003 designation is the one formally specified for this motorcycle.
