The International 8500 TranStar uses 9007 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2008 to 2011 vehicle production years 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 International 8500 TranStar uses the 9007 bulb for both high beam and low beam headlights across the 2008-2011 model years.
The 9007 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both high and low beam functions from one housing position.
The 9007 operates on a 12-volt electrical system and draws 65 watts on the high beam filament and 55 watts on the low beam filament.
The 9007 uses a PX29t base, which is a specific connector type that determines physical fitment into the headlight socket and is not interchangeable with other base configurations.
The 9007 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of performance and construction criteria under North American standards.
Because the same bulb type serves both beam functions on the 8500 TranStar, a single replacement part number covers both the high beam and low beam positions.
