Frequently Asked Questions About International ProStar LED Headlights

What years and models of International ProStar are these LED headlights compatible with?

These LED headlights are designed to fit International ProStar models from 2008 to 2017. They are direct replacements for the factory halogen headlights found on all ProStar trim levels during these years. However, the 2017 models that came with factory LED lights require different connectors, so please verify your original headlight type before ordering. The mounting points and electrical connections are identical to OEM specifications for plug-and-play installation on compatible models.

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

Installation typically takes 30-45 minutes per side and requires basic hand tools including a Phillips screwdriver, 10mm socket, and trim removal tools. The process involves removing the grille surround, disconnecting the original headlight harness, removing three mounting bolts, and reversing the process with the new LED units. Most customers report no cutting or splicing is required, though some 2008-2010 models may need a polarity adapter (usually included). We recommend having a second person help align the headlights during installation to ensure proper fitment.

What is the actual light output and beam pattern compared to stock halogen lights?

Our LED headlights produce approximately 12,000 lumens per pair compared to 3,000 lumens from stock halogens, providing 4x brighter illumination. The beam pattern is DOT compliant with a sharp cutoff line that prevents blinding oncoming traffic. The color temperature is 6000K pure white, eliminating the yellowing common with older halogens. Many drivers report seeing road signs clearly at 500+ feet and significantly improved visibility in rain and fog conditions.

Are these headlights truly waterproof, and how long do they last?

These LED headlights feature IP67 waterproofing with sealed housings and moisture-resistant breather vents. The polycarbonate lenses are UV-resistant to prevent yellowing and cracking. The LED chips are rated for 50,000 hours of operation, which typically translates to 10-15 years of normal commercial use. Each unit includes integrated cooling fans that activate automatically to prevent overheating. We back these with a 2-year warranty against defects and water intrusion.

Will these LED headlights work with my ProStar's DRL (Daytime Running Lights) system?

Yes, these LED headlights are fully compatible with the ProStar DRL system. They include built-in resistors to prevent hyperflashing and error messages on your dashboard. The dual-function design provides both low beam and high beam operation, with the DRL function operating at 50% brightness during daytime use. Some 2008-2009 models may require an additional DRL decoder (sold separately) to eliminate dashboard warnings, but 2010 and newer models work perfectly without any additional components.
