Frequently Asked Questions About International 4700-4900 Cab Lights

Will these cab lights fit my specific year International 4700 or 4900?

Most aftermarket cab lights for International 4700 and 4900 models are designed to fit trucks from 1989 through 2002. However, there are slight variations in roof profiles between early models (1989-1994) and later models (1995-2002). Always verify the specific year range listed for each product. If your truck has a curved roof profile, you'll need lights with adjustable mounting brackets or curved base plates to ensure proper fitment.

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

LED cab lights draw significantly less power (typically 0.1-0.3 amps per light versus 1-2 amps for incandescent), last up to 50,000 hours compared to 2,000 hours for traditional bulbs, and produce brighter, more consistent light. While LED options cost more upfront, they eliminate frequent bulb replacements and reduce electrical system strain. Incandescent lights remain popular for their classic warm glow and lower initial cost, making them ideal for show trucks or budget-conscious installations.

Do I need to drill holes in my cab roof to install these lights?

Yes, most cab light installations require drilling five holes in your roof - one for each light housing. Each hole typically measures 3/4" to 1" in diameter. Professional installation is recommended if you're not comfortable drilling through your cab. Some installers use a template to ensure proper spacing (usually 6-8 inches apart). Always apply rust-preventive primer to drilled holes and use quality silicone sealant around each light base to prevent water leaks.

What wiring modifications are needed to install aftermarket cab lights?

You'll need to run new wiring from your truck's clearance light circuit to the cab roof. Most kits include a wiring harness that connects all five lights in series. The typical installation involves tapping into the existing clearance light wire (usually behind the headlight switch or at the rear clearance lights), running 14-16 gauge wire through the headliner, and connecting to each light. Total installation time ranges from 2-4 hours depending on your experience level.

What styles and finishes are available, and how do I match my truck?

Cab lights come in several styles including the classic Grakon style (rectangular), watermelon style (oval), and modern aero designs. Finish options include chrome plastic, die-cast chrome, amber lens, clear lens, and smoked lens varieties. For International 4700-4900 trucks, the traditional amber lens with chrome base remains most popular as it matches factory clearance lights. Consider your truck's trim level and existing chrome accessories when selecting a finish to ensure a cohesive appearance.
