The Peterbilt 382 high beam and low beam headlight bulbs both utilize a 9007 size. The replacement chart covers vehicle production spanning 2011 to 2017.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9007 bulb is the sole headlight bulb type specified for the Peterbilt 382 across all listed model years.
The 9007 bulb is a dual-filament halogen bulb, meaning a single unit contains separate filaments for both high beam and low beam operation.
Because the 9007 serves both the high beam and low beam positions on the Peterbilt 382, the same bulb part number applies to both headlight functions for model years 2011-2017.
The 9007 bulb operates at 65 watts on the high beam filament and 55 watts on the low beam filament, with a base voltage rating of 12 volts.
The 9007 uses an HB5 base configuration, which is a three-contact connector designed specifically to support dual-filament operation within a single housing.
The 9007 and 9004 bulbs share a similar appearance but are not interchangeable, as their connector keyways are oriented differently to prevent incorrect installation, and their wattage ratings also differ.
