Additional Notes

The Peterbilt 386 uses the 9007 bulb for both high beam and low beam headlights across the 2011-2016 model years. The 9007 is a dual-filament halogen bulb operating at 12V with a high beam draw of 65W and a low beam draw of 55W, fitted with a PX29t base.
For the 2006-2009 model years, the Peterbilt 386 headlight bulb fitment varies depending on which of three headlamp configurations the vehicle was built with: a 2-rectangular-headlamp setup, a 4-rectangular-headlamp setup, or a halogen capsule headlamp setup. Selecting the wrong bulb type for the installed configuration results in an incompatible fitment.
The H6054 is a 5x7-inch rectangular sealed beam unit used in the 2-rectangular-headlamp configuration for both high and low beam positions on 2006-2009 models. As a sealed beam unit, the entire assembly is replaced rather than an individual bulb, and it operates at 12V.
The 9004 bulb serves both high and low beam functions in the halogen capsule headlamp configuration on 2006-2009 models. It is a dual-filament halogen bulb with a P29t base, rated at 12V with 65W on high beam and 45W on low beam.
The 4-rectangular-headlamp configuration on 2006-2009 models uses separate sealed beam units for high and low beam positions. The H4651 covers the high beam position, while the low beam position uses the H4652 for 2006, 2008, and 2009, and the H4656 for 2007.
The H4651, H4652, and H4656 are all 4x6-inch rectangular sealed beam units operating at 12V. Despite sharing the same physical format, they are distinct part numbers and are not interchangeable across beam positions or model years without confirming the correct designation for the specific application.
The 9007 and 9004 bulbs share a similar dual-filament halogen design but differ in base type and wattage output. The 9007 uses a PX29t base and draws 65W/55W, while the 9004 uses a P29t base and draws 65W/45W. These differences make the two bulbs non-interchangeable despite their outward similarity.
All bulb and sealed beam types listed for the Peterbilt 386 conform to ANSI standards applicable in the United States and Canada, covering both the replaceable halogen bulbs and the sealed beam units across all documented model years.
