International 4300LP high beam and low beam headlight bulbs use 9007 size. The replacement chart covers 2011 to 2018 vehicle production years with bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International 4300LP uses the 9007 bulb type for both high beam and low beam headlights across all listed model years from 2011-2018.
The 9007 is a dual-filament halogen bulb, meaning a single bulb contains separate filaments for high and low beam functions, which is why the same part number serves both lighting positions.
Because the 9007 handles both beam functions within one unit, the headlight assembly on the 4300LP does not require separate bulbs for each beam mode.
The 9007 bulb operates on a standard two-filament design rated at 65 watts for high beam and 55 watts for low beam, reflecting the different luminous output required for each function.
The 9007 uses an HB5 base configuration, which is a specific connector type not shared with other common dual-filament bulbs such as the 9004, making cross-substitution between those types incompatible without modification.
The consistency of the 9007 specification across the entire 2011-2018 production span indicates that the headlight housing design remained unchanged throughout those model years.
