Peterbilt 567 high beam headlight bulbs use 9005XS or 9005 sizes, while low beam headlight bulbs use H11 or D1S sizes. The chart covers 2014 to 2020 and contains replacement bulb size specifications for these vehicle production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9005XS is the high beam bulb type used in the Peterbilt 567 for 2018-2020, as well as the 2016 model year with halogen capsule headlamps. The 9005XS is a variant of the standard 9005 bulb featuring a shorter base, which affects physical fitment even though the two types share the same electrical rating of 65 watts at 12 volts.
The standard 9005 bulb applies to the high beam position on the 2014, 2015, and 2017 Peterbilt 567, all specified under the halogen capsule headlamp configuration. The 9005 and 9005XS are not directly interchangeable due to the difference in base length, meaning substituting one for the other risks improper seating within the headlamp housing.
The H11 bulb is the low beam type across all model years from 2014 through 2020 when halogen capsule headlamps are fitted. The H11 is a single-filament halogen bulb rated at 55 watts, belonging to the PGJ19-2 base family, and is widely used across the automotive industry in low beam and fog light applications.
For the 2018-2020 Peterbilt 567, the low beam position accommodates either an H11 or a D1S bulb depending on whether the vehicle is equipped with halogen capsule headlamps or HID headlamps respectively. These two bulb types operate on fundamentally different technologies and are not interchangeable under any circumstance.
The D1S is a high-intensity discharge bulb that requires a factory-integrated igniter and a dedicated ballast to function. It operates at a much higher voltage than halogen types and produces light through an electrical arc between two electrodes within a quartz capsule filled with xenon gas and metal halide salts.
Because the D1S low beam option on the 2018-2020 models is tied specifically to the HID headlamp system, replacing a failed D1S bulb with an H11 is not a valid substitution, as the HID housing and ballast are designed exclusively around the discharge bulb's operating characteristics.
The 2016 model year presents a split fitment for the high beam position, where the 9005XS is specified under the halogen capsule headlamp condition, while the 2017 model year reverts to the standard 9005 under the same headlamp condition. This means adjacent model years within the halogen capsule configuration do not share the same high beam bulb type.
The 2014 and 2015 model years share identical bulb specifications across both the high beam and low beam positions, with the 9005 serving the high beam and the H11 serving the low beam, both under the halogen capsule headlamp designation.
