Frequently Asked Questions About Kenworth W900B/W900L Cab Lights

What years and models are these cab lights compatible with?

Our Kenworth W900B/W900L cab lights are designed to fit W900B models from 1987-2010 and W900L models from 1988-2010. However, compatibility can vary based on whether you have an AeroCab or Studio Sleeper configuration. We recommend checking your specific cab style before ordering, as mounting hole patterns may differ between early and late model years. If you're unsure about fitment, please contact us with your truck's VIN for verification.

Are these cab lights DOT approved and what's the difference between LED and incandescent options?

Yes, all our cab lights meet DOT requirements for clearance and marker lights. LED options offer 50,000+ hour lifespan, draw less power, and provide brighter illumination compared to traditional incandescent bulbs. LEDs also generate less heat and are more resistant to vibration damage. Incandescent lights are typically less expensive upfront but require more frequent bulb replacements. Most customers choose LED for the long-term savings and reliability.

How difficult is the installation process and what tools are required?

Installation typically takes 2-4 hours depending on your experience level. You'll need a drill with appropriate bits, wire strippers, electrical connectors, and basic hand tools. Most cab lights require drilling five holes per light assembly. We strongly recommend using a template to ensure proper spacing and alignment. Many customers report that removing the headliner provides easier access for wiring, though it's possible to install without removal. Professional installation typically runs $200-400 if you prefer not to DIY.

What styles and finishes are available for W900B/W900L cab lights?

We offer several popular styles including the classic "Maxi" style round lights, rectangular "Fleet" style, and teardrop "Bullet" style options. Finishes include chrome plastic, die-cast chrome, stainless steel, and black powder-coated options. Chrome plastic is the most economical but may show wear over time. Stainless steel provides the best durability and corrosion resistance for harsh weather conditions. Most styles are available in both amber and clear lens options to match your preference or state requirements.

Do these cab lights come as complete kits or do I need to purchase components separately?

Most of our cab light kits include the light assemblies, mounting gaskets, and basic hardware. However, wiring harnesses are often sold separately as routing can vary significantly between trucks. Complete kits with pre-made harnesses are available for common configurations. You may also need additional items like grommets, junction boxes, or switches depending on your specific installation. We recommend reviewing the "What's Included" section on each product page or calling us to ensure you have everything needed for your installation.
