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 the light source, beam functions, electrical requirements and connectors. Heated lenses, projection optics and other features apply only where explicitly specified in the listing.
Check the installation package

Before ordering: Have your vehicle model, year and photos of the current headlight assembly ready. Similar-looking headlights and matching model names do not establish compatibility.
Freightliner headlight FAQs
What Freightliner models can I shop by?
Choose from the M2/S2RV, Cascadia, Century, Classic and Columbia headlight collections above. The shared M2/S2RV collection does not mean that every item fits both applications; check each listing’s fitment details.
How do I choose the correct Freightliner headlight assembly?
Identify the model and year, then compare the existing housing shape, mounting points, connectors and driver or passenger side. Confirm the listed original lighting configuration before selecting a replacement.
Are all Cascadia headlights interchangeable?
Do not assume interchangeability based on the Cascadia name alone. Match the specific year range and original headlight configuration in the listing, together with the mounting arrangement and electrical connections.
What should I compare between LED and factory-style replacement headlights?
Check the exact product’s light source, beam functions, electrical requirements and included components. Confirm whether it uses replaceable bulbs or integrated LED modules and review the installation requirements for your truck.
Are Freightliner replacement headlights plug-and-play?
Installation depends on the product and truck configuration. Check the wiring, mounting points and any required adapters or conversion parts. Follow the instructions for the selected assembly rather than assuming every replacement installs without modification.
Do headlight assemblies include bulbs and hardware?
Package contents vary. A housing, a complete assembly and a replacement bulb are different products. Review the included-parts list for bulbs, LED modules, adapters and mounting hardware before ordering.
How should I compare headlight beam performance?
Use the beam information and specifications supplied for the exact product. Compatibility, installation and correct aiming matter alongside output. Do not assume every LED option produces the same beam pattern or performance.
What should I check for on-road use?
Review the exact product’s markings, intended use and supporting documentation, together with the requirements where the vehicle operates. Ask for clarification if the listing does not address your application; category membership alone does not establish approval.
