Additional Notes

The Peterbilt 384 (2011-2016) uses the 9007 bulb for both high beam and low beam headlights. The 9007 is a dual-filament halogen bulb with a PX29t base, rated at 12V with 65W on high beam and 55W on low beam, conforming to ANSI standards for the US and Canadian markets.
The 9004 bulb also follows the dual-filament halogen design and shares the same 12V rating as the 9007, but draws less wattage on low beam at 45W versus 55W. Its base type is P29t rather than PX29t, making the two bulbs physically incompatible despite their similar appearance and function.
The 2008-2009 Peterbilt 384 with halogen capsule headlamps uses the 9004 bulb for both high and low beam positions, serving as a single dual-filament unit that handles both functions.
On 2008-2009 models equipped with 2 rectangular headlamps, the H6054 sealed beam unit is specified. This is a 5x7-inch sealed beam assembly rated at 12V in which the lens, reflector, and filament form a single unit, requiring full assembly replacement rather than bulb replacement.
The H4651 and H4652 are both 4x6-inch rectangular sealed beam units used on 2008-2009 models with 4 rectangular headlamps. The H4651 handles the high beam position and the H4652 handles the low beam position. Like the H6054, neither accepts a replaceable bulb.
The H4651 and H4652 are variants of the same 4x6-inch sealed beam format. Although they share physical housing proportions, they are not interchangeable, as each is designed for a specific beam function within a four-lamp headlamp configuration.
All bulb types listed across both the 2008-2009 and 2011-2016 model years conform to ANSI standards applicable in the US and Canada, and all operate on a 12V electrical system.
The headlamp system on the Peterbilt 384 changed between the 2009 and 2011 model years. The 2008-2009 configurations offered three distinct headlamp arrangements, each requiring different bulb types, while the 2011-2016 configuration standardized on the single 9007 bulb for both beam functions.
