Frequently Asked Questions About Freightliner Columbia 112/120 Cab Lights

Will these cab lights fit my specific year Freightliner Columbia?

Our cab lights are designed to fit Freightliner Columbia 112 and 120 models from 2000-2017. The mounting patterns are identical across these years, so you can install them on any Columbia within this range. However, if your truck has aftermarket visors or custom roof modifications, you may need to adjust the mounting location or use extended wiring harnesses.

What's the difference between LED and incandescent cab lights, and which should I choose?

LED cab lights draw 80% less power, last up to 50,000 hours compared to 2,000 hours for incandescent bulbs, and provide brighter, more consistent illumination. While LEDs cost more upfront, they eliminate frequent bulb replacements and reduce electrical system strain. Incandescent lights are budget-friendly and work with older wiring systems without modifications. Most drivers upgrading choose LEDs for the long-term savings and reliability.

How difficult is the installation, and what tools do I need?

Installation typically takes 2-4 hours depending on your experience level. You'll need a drill with 3/4" and 1" bits, wire strippers, electrical tape or heat shrink tubing, and silicone sealant. The process involves drilling five holes in your cab roof, running wiring to your clearance light circuit, and sealing all penetrations. Many customers successfully complete this as a weekend project, though professional installation runs $150-300 if you prefer.

Are these lights DOT compliant, and what styles are available?

Yes, all our Freightliner Columbia cab lights meet DOT FMVSS 108 requirements for clearance and identification lamps. We offer classic round lights, rectangular styles, and watermelon-shaped designs in amber, clear, red, and smoked lenses. Chrome, black powder-coated, and stainless steel bases are available. The most popular combination is amber watermelon LEDs with chrome bases, matching the Columbia's factory styling.

How do I prevent water leaks after installation?

Proper sealing is critical to prevent cab leaks. Use a high-quality silicone sealant rated for automotive use around each light base and wire entry point. Apply sealant to the mounting surface before installing the light, then add another bead around the base after tightening. For the wire holes, use rubber grommets with sealant. Many installers also add a thin rubber gasket under each light base for extra protection. Re-check and refresh sealant annually during regular maintenance.
