International DuraStar Lights

Frequently Asked Questions About International DuraStar Lights

What years and models of International DuraStar trucks are these lights compatible with?

Our International DuraStar lights are designed to fit 2002-2018 DuraStar 4000 series models, including the 4100, 4200, 4300, and 4400. Most headlights, tail lights, and marker lights are direct replacements for these model years. However, some 2017-2018 models may have different wiring harnesses, so we recommend checking your OEM or calling our tech support at 1-888-875-7787 before ordering to ensure proper fitment.

Are these aftermarket lights DOT approved and legal for road use?

Yes, all International DuraStar lights we carry are DOT compliant and SAE certified for legal road use in all 50 states. Each light includes proper DOT markings on the lens. We only stock lights from reputable manufacturers like United Pacific, Grand General, and Truck-Lite that meet or exceed OEM specifications for brightness, beam pattern, and durability.

How difficult is it to install these lights, and what tools do I need?

Most DuraStar light replacements are straightforward plug-and-play installations that take 30-60 minutes per light. You'll typically need basic hand tools including Phillips and flathead screwdrivers, a 10mm socket, and wire strippers for any splice connections. Headlight assemblies require removing 4-6 mounting bolts and unplugging the factory harness. LED upgrades may require adding a load resistor to prevent hyper-flashing, which we include with applicable lights.

What's the difference between halogen and LED options, and which should I choose?

LED lights offer 50,000+ hour lifespan compared to 1,000-2,000 hours for halogen, use 80% less power, and provide brighter, whiter light output. However, LEDs cost 2-3 times more upfront. Halogen lights are more affordable and work with all factory wiring without modifications. Choose LED if you want long-term savings and better visibility, or halogen if you need the lowest initial cost and simple compatibility.

Do these lights come with a warranty, and how do returns work if they don't fit?

All lights carry manufacturer warranties ranging from 1 year for basic halogen units to limited lifetime for premium LED models. If a light doesn't fit your specific DuraStar model, you have 30 days to return it in new, unused condition for a full refund minus shipping costs. We recommend test-fitting lights before final installation to ensure compatibility. Contact our customer service team for warranty claims or return authorization.
