Shop Peterbilt headlights by model

Select your model, then check the individual product’s application and specifications.

Choose the right Peterbilt headlight setup

Identify your existing lights

Check the model, year, housing shape and mounting points. Confirm whether you need a complete assembly, a housing, a replacement bulb or conversion components.

Compare the exact specifications

Review LED or halogen construction, beam functions, voltage and connections in the listing. Heated lenses, projection optics and other features apply only where explicitly specified.

Check the installation package

Confirm the required side, quantity and included bulbs, modules, adapters and hardware. Match the existing wiring and follow the instructions for the selected product.

Before ordering: Have your truck’s model, year and photos of the current headlight assembly ready. Similar-looking headlights and matching model names do not establish compatibility.

Peterbilt headlight FAQs

What Peterbilt models can I shop by?

Choose from the 359, 379, 386, 389, 567, 579 and 589 headlight collections above. Fitment can vary by year and original lighting configuration, so confirm the exact application in each listing.

How do I choose the correct headlight assembly?

Start with your Peterbilt model and year. Compare the existing housing shape, mounting points, connectors and driver or passenger side with the listed replacement. Photos of the current lights and their markings can help identify the required setup.

What should I compare between LED and halogen options?

Compare the specific product’s beam functions, power requirements, included components and installation notes. Check whether it uses a replaceable bulb or an integrated LED module. Choose based on the complete assembly and your truck’s requirements rather than the light source alone.

Are Peterbilt replacement headlights plug-and-play?

Installation requirements depend on the product and truck configuration. Some replacements use the existing mounting points and connectors, while conversions may require additional wiring or mounting components. Check the listing before ordering.

Do headlight assemblies include bulbs or LED modules?

Package contents vary. A complete assembly, housing, conversion bucket and replacement bulb are different products. Review the included-parts list and confirm whether bulbs, LED modules, adapters or mounting hardware are supplied.

Can I convert an older Peterbilt to LED headlights?

Compare the available conversion components with your existing lamp size, housing and mounting arrangement. Confirm the beam function, connections and any required adapters or brackets for the exact product before purchasing.

How should I compare headlight beam performance?

Use the specifications and beam information supplied for the exact headlight. Compatibility, installation and correct aiming matter alongside output. Do not assume that every LED option produces the same beam pattern or performance.

What should I check for on-road use?

Review the markings and intended use of the exact product, along with the requirements that apply where the truck operates. Ask for product-specific documentation if the listing does not answer your question; category membership alone does not establish approval.
