Mack CX Truck Cab Lights
Frequently Asked Questions About Mack CX Truck Cab Lights
Will these cab lights fit my specific Mack CX model year?
Most aftermarket cab lights for Mack CX trucks are designed to fit models from 2003-2010. However, there can be slight variations in mounting hole patterns between early and late production years. We recommend checking your existing mounting holes or contacting us with your VIN to ensure proper fitment. Some 2011+ models may require additional drilling or modification brackets.
What's the difference between LED and incandescent cab lights for my Mack CX?
LED cab lights draw significantly less power (typically 80% less), last 50,000+ hours compared to 2,000 hours for incandescent bulbs, and provide brighter, more consistent illumination. While LED options cost more upfront, they eliminate frequent bulb replacements and reduce electrical strain on your truck. Incandescent lights are cheaper initially but require regular maintenance and generate more heat.
How difficult is the installation process, and what tools do I need?
Installation typically takes 2-4 hours depending on your experience level. You'll need a drill with metal bits, wire strippers, electrical tape or heat shrink tubing, silicone sealant, and basic hand tools. The main challenges include drilling precise holes in the cab roof, properly sealing against water intrusion, and routing wiring to your electrical system. Many drivers recommend using a template or the old lights as a guide for hole placement.
Are amber or clear lenses better for Mack CX cab lights?
Amber lenses are the traditional choice and required by DOT regulations in many states for vehicles over 80 inches wide. They provide better visibility in fog and adverse weather conditions. Clear lenses with amber bulbs offer more flexibility if you want to change colors later but may not meet all state requirements. Check your local regulations before choosing, as some states mandate amber forward-facing marker lights.
How do I prevent water leaks after installing new cab lights?
Proper sealing is critical to prevent cab leaks. Use a high-quality silicone sealant rated for automotive use around each light base before mounting. Apply sealant to the mounting screws and any drilled holes. Many installers also recommend adding a rubber gasket or butyl tape between the light and cab surface for extra protection. Inspect and reapply sealant annually, especially after pressure washing.
