Headlight Assembly For 2004-2017 Freightliner Columbia Chrome Housing And Amber Reflective Headlights Left And Right Pairs Halogen Bulbs Included

Keep your Freightliner Columbia running safe and looking sharp with a direct-fit headlight assembly built specifically for 2004-2017 model years. This complete left-and-right pair ships with halogen bulbs already included, so you can get back on the road without extra trips to the parts counter. COMPATIBILITY This headlight assembly is engineered to fit all 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, and 2017 Freightliner Columbia Class 8 semi trucks. Whether you operate a regional hauler, a long-haul rig, or a vocational Columbia spec'd for construction or tanker duty, this pair replaces worn, yellowed, or cracked OEM-style units on both the driver side (left) and the passenger side (right) simultaneously. Always confirm your specific VIN and trim before installation. If you are unsure, consult your fleet manager or reference the Freightliner Columbia parts catalog for your build date. BENEFITS • Complete Left & Right Pair — One purchase covers both sides, eliminating mismatched housings and reducing downtime. • Halogen Bulbs Included — Ready-to-install straight from the box; no additional bulb purchases required before your truck hits the road. • Chrome Housing Finish — Polished chrome interior reflects maximum light output forward while giving the cab a clean, professional appearance. • Amber Reflective Side Markers — Integrated amber reflectors improve side visibility and help meet Federal Motor Vehicle Safety Standards (FMVSS) for commercial vehicles. • Direct OEM-Style Fit — Designed to align with factory mounting points and wiring connectors, minimizing installation time for owner-operators and fleet mechanics alike. • Improved Night-Visibility — Restored, clear optics and fresh halogen bulbs dramatically outperform clouded, aging factory lenses on high-mileage rigs. TECHNICAL SPECS • Fitment: 2004–2017 Freightliner Columbia (all configurations) • Included: Driver-side (left) assembly + passenger-side (right) assembly • Bulb Type: Halogen (bulbs pre-installed) • Housing Finish: Chrome-plated reflector bowl • Reflector Color: Amber • Lens Material: Impact-resistant polycarbonate • Housing Material: Chrome-plated ABS thermoplastic • Mounting: Direct bolt-on to OEM mounting points; plug-and-play wiring connector MATERIALS & BUILD QUALITY The housing on these assemblies is constructed from high-density ABS thermoplastic with a chrome-plated interior reflector bowl. ABS offers excellent resistance to road vibration, temperature cycling, and the chemical exposure common in commercial trucking environments — diesel fuel mist, road salt, and cleaning solvents. The outer lens is formed from optical-grade polycarbonate, which provides superior impact resistance compared to standard acrylic. Polycarbonate lenses are less prone to shattering from road debris and maintain optical clarity longer under UV exposure when properly sealed. The amber reflector inserts are precision-molded to direct light in compliance with DOT visibility requirements. All seams are sealed against moisture intrusion to prevent the internal fogging and condensation buildup that shortens headlight life on long-haul trucks operating in rain, snow, and humidity. The result is a durable, road-ready assembly that performs reliably across hundreds of thousands of miles when properly maintained. INSTALLATION GUIDE Installing this headlight assembly on a 2004–2017 Freightliner Columbia is a straightforward job achievable with basic hand tools in under two hours. Begin by parking the truck on a level surface and switching off the ignition. Disconnect the negative terminal of the battery to eliminate any risk of electrical shorts during the swap. Open the hood and locate the headlight mounting bolts — typically three to four bolts per assembly on the Columbia. Using a socket wrench, remove the mounting hardware and gently pull the old assembly forward. Reach behind the housing to disconnect the wiring harness connector by pressing the release tab and pulling straight back. Do not twist the connector. Set the old assembly aside. Unbox the new driver-side or passenger-side assembly and connect the wiring harness — it will click securely when fully seated. Position the assembly into the mounting cavity, aligning all bolt holes with the factory threads. Hand-tighten the mounting bolts first to confirm alignment, then torque them down snugly (do not over-torque ABS-mounted hardware). Repeat the process for the opposite side. Reconnect the battery, start the truck, and test both low-beam and high-beam functions before closing the hood. Final step: perform a headlight aim check using a flat wall or floor markings per FMVSS 108 requirements to ensure beams are properly aligned for safe nighttime operation.
