Frequently Asked Questions About International WorkStar LED Headlights

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

These LED headlights are designed to fit International WorkStar models from 2008 to 2017. They are direct replacements for the standard 4x6 inch rectangular sealed beam headlights found on WorkStar 7300, 7400, 7500, and 7600 series trucks. Always verify your specific truck's headlight configuration before ordering, as some special editions or custom builds may have different setups.

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

Installation is typically straightforward and takes about 30-45 minutes per side. You'll need basic hand tools including a Phillips screwdriver, socket set (usually 10mm), and wire strippers if your LED lights require adapter harnesses. Most LED headlights are plug-and-play with the existing 3-prong H4 connectors, though some models may require polarity adapters. No cutting or drilling is required for standard installations.

What's the actual difference in brightness and visibility compared to stock halogen lights?

LED headlights typically produce 3,000-4,500 lumens per light compared to 700-1,000 lumens from stock halogens. This translates to approximately 200-300% more light output with a cleaner, whiter light (5,000-6,000K color temperature) that reduces eye strain during night driving. The beam pattern is also more focused, providing better road illumination without blinding oncoming traffic when properly aimed.

Are these LED headlights DOT approved and legal for on-road use?

Quality LED headlights for WorkStar trucks should be DOT approved and SAE compliant for legal street use. Look for lights that specifically state "DOT approved" in their specifications and have the DOT marking stamped on the lens. Be aware that some off-road only LED lights are available but these are not legal for highway use and may result in inspection failures or citations.

How long do these LED headlights last, and what kind of warranty should I expect?

LED headlights typically last 30,000-50,000 hours compared to 500-1,000 hours for halogen bulbs. This means they should outlast your truck under normal use conditions. Most reputable brands offer 2-5 year warranties, with some providing lifetime warranties. Look for lights with aluminum housings and proper heat sinks, as these features significantly extend LED lifespan by managing heat effectively.
