Frequently Asked Questions About Freightliner Coronado Cab Lights

Will these cab lights fit my specific year Freightliner Coronado?

Our cab lights are designed to fit Freightliner Coronado models from 2001 to present. However, there are slight variations between the SD (2001-2009) and 122SD/132 (2010-current) models. The mounting hole patterns are identical, but the SD models have a slightly flatter roof profile. Always check the product description for specific year compatibility, or contact our support team with your VIN for verification.

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, and provide brighter, more consistent illumination. They also generate less heat, reducing lens warping and housing damage. While LED options cost more upfront, they eliminate frequent bulb replacements and reduce electrical strain on your truck. Most customers switching to LED report the investment pays for itself within 18 months through reduced maintenance.

Can I install these cab lights myself, or do I need professional installation?

Installation typically takes 2-3 hours and requires basic electrical knowledge. You'll need to remove the headliner, drill mounting holes (if replacing different style lights), run wiring to your clearance light circuit, and seal all penetrations with silicone. The most challenging part is accessing the wiring behind the headliner. Many drivers successfully complete this installation, but if you're uncomfortable with electrical work or drilling into your cab roof, professional installation runs $150-300.

What styles and lens colors are available, and are they DOT compliant?

We offer Coronado cab lights in classic teardrop, rectangular, and watermelon styles. Lens colors include amber (required for front-facing clearance lights), clear, red, and smoked. All our cab lights meet DOT FMVSS 108 requirements when amber lenses are used in the front positions. Popular combinations include amber teardrops for a classic look or smoked rectangular LEDs for a modern appearance. Chrome, black, and stainless steel bezels are available depending on the model.

How do I prevent water leaks after installing new cab lights?

Water leaks are the number one installation issue. Use a high-quality silicone sealant (not standard caulk) rated for automotive use around all mounting holes and wire entry points. Apply sealant to both the light base gasket and the cab surface before mounting. Create a small loop in the wiring before it enters the cab (drip loop) to prevent water from following the wire inside. Re-check and refresh sealant annually, especially if you frequently pressure wash your truck. Many customers also add a thin bead of clear RTV around the light base after installation for extra protection.
