Freightliner Cascadia 113/125 Cab Lights

Frequently Asked Questions About Freightliner Cascadia 113/125 Cab Lights

Will these cab lights fit both the 113 and 125 Cascadia models?

Yes, cab lights listed in this category are designed to fit both the Freightliner Cascadia 113 and 125 models, since the cab marker light mounting locations are the same across both wheelbase versions. Always double check the year range listed on each product page, as Freightliner made some body and trim updates over the years that can affect fitment.

Are these cab lights DOT compliant and legal for road use?

Most cab lights in this category are designed to meet DOT and FMVSS 108 requirements for marker and clearance lighting, but compliance can vary by specific product. Check the product description or packaging for DOT certification markings before installation, and confirm the light color and placement meet the lighting regulations in your operating area.

Do these lights come with the wiring and mounting hardware needed for installation?

Many cab light kits include the mounting grommets, gaskets, and pigtail wiring harnesses needed for a direct plug and play installation, but this varies by product, so review the item description for what is included. If hardware is not included, you can typically reuse your factory grommets and connectors as long as the new light uses a compatible bulb or LED base.

Can I install LED cab lights myself, or do I need a professional?

Most cab lights are designed for a straightforward bolt in replacement using the existing mounting holes and wiring connections on your Cascadia, so many owners install them at home with basic hand tools. If your truck has a sealed or non-standard wiring setup, or if you are converting from incandescent to LED and need to address hyperflash or resistor issues, it may be worth having a shop handle the wiring.

What is the difference between amber, clear, and smoked lens cab lights?

Amber lenses are the most common factory-style option and are widely accepted for clearance and marker lighting compliance. Clear lenses typically use amber or colored bulbs behind the lens to maintain proper light color while giving a different daytime appearance, while smoked lenses offer a darker, more custom look but may reduce visible brightness and could affect compliance depending on local regulations, so verify legality in your area before choosing this style.
