Kenworth W990 LED Headlights

Frequently Asked Questions About Kenworth W990 LED Headlights

Will these LED headlights fit my specific year Kenworth W990?

Our LED headlights are designed to fit all Kenworth W990 models from 2018 to present. The W990 uses a standard 7-inch round headlight configuration, making these lights a direct replacement for your factory halogen units. However, if your truck has been modified with custom headlight buckets or non-standard mounting hardware, you may need additional adapters. We recommend checking your current headlight diameter before ordering.

Do I need any special wiring or adapters to install these LED headlights?

Most of our W990 LED headlights are plug-and-play with the factory H4 connector, requiring no cutting or splicing of wires. However, some trucks may experience flickering or dashboard warnings due to the lower power draw of LEDs compared to halogens. In these cases, you'll need to install load resistors or a CANbus decoder, which we offer separately. Installation typically takes 30-45 minutes per side with basic hand tools.

How much brighter are LED headlights compared to my stock halogens?

Our LED headlights typically produce 3,000-4,500 lumens per bulb, compared to 1,000-1,500 lumens from standard halogen bulbs. This translates to approximately 200-300% more light output with a cleaner, whiter beam pattern. The color temperature ranges from 5,000K to 6,500K, providing better visibility in rain, fog, and nighttime conditions without blinding oncoming traffic when properly aimed.

What styles and finishes are available for W990 LED headlights?

We offer several styles including classic round sealed beam replacements, projector-style units with halo rings, and models with integrated turn signals or position lights. Finish options include chrome reflector bowls, black housings, and clear or smoked lenses. Some models feature customizable RGB halos that can be controlled via smartphone app. All styles maintain DOT compliance for legal road use.

How long do these LED headlights last, and what warranty coverage is included?

Quality LED headlights typically last 30,000-50,000 hours of operation, compared to 500-1,000 hours for halogen bulbs. This translates to approximately 10-15 years of normal driOEMg use. Most manufacturers offer warranties ranging from 1-3 years against defects. Common issues covered include moisture intrusion, LED failure, and housing defects. Always register your lights upon purchase to ensure warranty coverage.
