International LT Lights

Frequently Asked Questions About International LT Lights

What years and models of International LT trucks do these lights fit?

Our International LT lights are designed to fit 2017-2025 International LT models. Most aftermarket lights are direct replacements that work with all trim levels including the LT625, LT625 SBA, and LT Series. However, some specialty lights may have specific fitment requirements, so always check the product description for your exact year and configuration. If you have a pre-2017 International model, you'll need to look at our ProStar or other International model-specific lighting options.

Are these lights DOT approved and street legal?

Yes, the majority of our International LT replacement headlights, tail lights, and marker lights are DOT approved and SAE certified for street use. Look for the DOT marking on the product page and lens itself. For auxiliary lights like light bars or additional fog lights, check your local and state regulations as requirements vary by jurisdiction. All required marker lights and turn signals we carry meet federal regulations for commercial vehicles.

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

Most International LT lights are designed as plug-and-play replacements requiring basic hand tools. Headlight assemblies typically take 30-45 minutes per side and require a socket set, screwdrivers, and possibly a trim removal tool. LED upgrades usually connect to existing harnesses without cutting or splicing. Some auxiliary lights may require drilling for mounting brackets and basic wiring knowledge. We recommend having a multimeter on hand to test connections, and many customers find having a second person helps with alignment during installation.

What's the difference between halogen and LED options for my International LT?

LED lights offer 50,000+ hour lifespan compared to 1,000-2,000 hours for halogen, use less power, and provide brighter, whiter light output. However, LED headlights cost 2-3 times more upfront. Halogen bulbs are cheaper to replace and work better in extreme cold without snow buildup issues some LEDs face. For International LT trucks with computer-controlled lighting, LED conversions may require load resistors or CAN-bus adapters to prevent error messages. Consider your climate, budget, and how long you plan to keep the truck when choosing.

Do these aftermarket lights come with warranties, and what about water/moisture issues?

Most quality International LT replacement lights include 1-3 year manufacturer warranties against defects. Premium LED options often carry 3-5 year warranties. The most common issue we see in reviews is moisture intrusion, particularly with lower-priced options. Look for lights with proper ventilation ports, quality gaskets, and IP67 or higher waterproof ratings. If you experience fogging, check that all seals are properly seated during installation. Many manufacturers will warranty replace lights with persistent moisture issues within the first year.
