International WorkStar Lights

Frequently Asked Questions About International WorkStar Lights

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

Our International WorkStar lights are designed to fit WorkStar models from 2008 through 2017. This includes the 7300, 7400, 7500, 7600, and 7700 series. Most headlights and marker lights are direct replacements for these model years, but we recommend checking your specific OEM with our customer service team if you have a transitional year model (2007-2008 or 2017-2018) as some variations exist.

Are these LED lights truly plug-and-play, or will I need to modify my truck's wiring?

Most of our LED headlights and marker lights for the WorkStar are genuine plug-and-play installations that connect directly to your existing wiring harness. However, some older WorkStar models (pre-2010) may require a load resistor or decoder for turn signals and DRL functions to prevent hyper-flashing. Installation typically takes 30-45 minutes per headlight with basic hand tools. No cutting or splicing of factory wiring is required for standard installations.

How do these aftermarket lights compare to OEM in terms of brightness and beam pattern?

Our LED headlights typically produce 8,000-12,000 lumens per bulb compared to the stock halogen's 1,000-1,500 lumens. The beam pattern is DOT/SAE compliant with a proper cutoff line to prevent blinding oncoming traffic. Many drivers report visibility improvements of 200-300% over stock lighting. All lights meet or exceed FMVSS-108 standards for on-road use.

What's included in a complete headlight set, and are mounting brackets different for chrome vs. black housings?

A complete headlight set includes both driver and passenger side assemblies with integrated turn signals and DRL functions. Each light comes with mounting hardware and instructions. The mounting brackets are identical for both chrome and black housing options - only the finish differs. Chrome bezels can be purchased separately if you want to change the appearance later without replacing the entire assembly.

How long is the warranty, and what issues are actually covered?

Our International WorkStar LED lights come with a 2-year warranty against manufacturing defects, LED failure, and moisture intrusion. The warranty covers premature LED burnout, lens cracking from normal use, and seal failures. It does not cover damage from accidents, improper installation, or modifications. Keep your receipt and register your lights online within 30 days of purchase for the fastest warranty service.
