The Freightliner Condor high beam headlight uses an H4651 bulb size while low beam headlights require either H4656 or H4652 bulb sizes. The replacement chart covers vehicle production years spanning 2001 through 2007 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 Freightliner Condor uses the H4651 bulb for the high beam headlight across all model years from 2001 to 2007, indicating a consistent fitment specification throughout this entire production span.
The H4651 is a sealed-beam rectangular lamp operating at 37.5 watts, designed specifically for high beam applications in commercial vehicle headlight assemblies.
The low beam headlight position uses the H4656 bulb for the 2001-2003 and 2005-2007 model years, making it the dominant low beam fitment across this range.
The H4656 is a sealed-beam rectangular lamp rated at 50 watts for low beam output, sharing the same physical housing format as other H46-series lamps but differing in wattage and beam pattern.
The 2004 model year Condor low beam headlight requires the H4652 bulb rather than the H4656, representing a fitment difference specific to that year that warrants attention during replacement.
The H4652 is a sealed-beam rectangular lamp rated at 40 watts, and while it shares the same general H46-series rectangular form factor as the H4656, the two bulbs are not interchangeable due to differences in wattage and beam optics.
All H46-series sealed-beam lamps follow a standardized rectangular format, but each suffix number denotes a distinct wattage rating and beam configuration, meaning substitution between types risks improper light output or non-compliance with lighting standards.
The consistent use of H4651 across all seven model years for the high beam position contrasts with the variation seen in the low beam position, where two different bulb types appear across the same span.
