The Freightliner Columbia high beam headlight uses a 9005XS bulb size while the low beam headlight requires a 9006XS bulb size. The replacement chart covers vehicle production years spanning 2000 to 2017 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Freightliner Columbia uses the 9005XS for the high beam headlight position across all model years from 2000-2017, representing an unbroken fitment consistency across an eighteen-year production span.
The 9005XS is a short-base variant of the standard 9005 bulb. The "XS" designation indicates a physically shorter base, which is engineered to fit housings with tighter clearance tolerances than those accommodating the full-size 9005.
Because the 9005XS and the standard 9005 share the same P20d base type and electrical ratings, the two are electrically compatible, but the physical base length difference means the standard 9005 may not seat correctly in housings designed for the XS variant.
The low beam headlight position across all model years from 2000-2017 uses the 9006XS, which follows the same short-base design principle as the 9005XS but is a single-filament bulb rated for low beam output rather than high beam.
The 9006XS is a short-base derivative of the 9006, sharing the same PX22d base family. As with the high beam pairing, the standard 9006 and the 9006XS are electrically equivalent but differ in base length, which affects physical fitment in restricted housings.
The 9005XS and 9006XS are not interchangeable with each other. The two bulbs use different base configurations, and their respective housings are keyed to prevent cross-installation between the high and low beam positions.
Both the 9005XS and 9006XS are halogen bulb types operating on a tungsten filament sealed within a halogen gas envelope, a construction that produces a higher color temperature and longer service life compared to standard incandescent bulbs of equivalent wattage.
The uniformity of bulb fitment across the entire 2000-2017 range means that a single bulb specification applies to the high beam position and a single specification applies to the low beam position throughout the Columbia's production run, with no year-specific exceptions noted in the data.
