Frequently Asked Questions About International LoneStar Cab Lights

Will these cab lights fit my specific year International LoneStar?

Most aftermarket cab lights are designed to fit International LoneStar models from 2009 to present. However, there can be slight variations between model years, particularly in roof curvature and existing wiring harness configurations. We recommend checking the specific product description for year compatibility or contacting our support team with your VIN to ensure proper fitment. Pre-2009 models may require additional modifications or different mounting hardware.

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, a center punch, masking tape, a measuring tape, wire strippers, and basic hand tools. The most challenging part is drilling through the cab roof, which requires careful measurement and steady hands. Many customers recommend using a template or having a second person help with alignment. Professional installation runs $200-400 if you prefer not to drill into your cab yourself.

What's the difference between LED and incandescent cab lights for my LoneStar?

LED cab lights draw significantly less power (typically 0.3 amps vs 2-3 amps for incandescent), last 50,000+ hours compared to 1,000-2,000 hours, and provide instant illumination without warm-up time. LEDs also generate less heat, reducing lens discoloration and housing damage. While LED options cost 30-50% more upfront, they eliminate frequent bulb replacements and reduce electrical system strain. Most LoneStar owners report LED upgrades pay for themselves within 18-24 months.

Are these cab lights DOT approved and legal in all states?

Quality aftermarket cab lights should carry DOT approval markings (look for "DOT" stamped on the lens). Federal regulations require amber front and side markers with red rear markers. However, some states have additional requirements regarding the number and placement of clearance lights. California, for example, has stricter regulations about aftermarket lighting modifications. Always verify your state's specific commercial vehicle lighting requirements before installation.

What should I do about water leaks after installing cab lights?

Proper sealing during installation is critical to prevent leaks. Use a high-quality silicone sealant rated for automotive use around each light base, and consider adding a rubber gasket if not included. Apply sealant to screw holes before inserting screws. Many installers also recommend using butyl tape under the light base for extra protection. If you experience leaks after installation, remove the lights, clean all surfaces thoroughly, and reseal with fresh silicone. Adding a small drain hole at the lowest point of each light housing can prevent water accumulation.
