Kenworth T800 Cab Lights
Frequently Asked Questions About Kenworth T800 Cab Lights
What year models of Kenworth T800 are these cab lights compatible with?
Most aftermarket cab lights for the Kenworth T800 are designed to fit models from 1987 through 2021. However, there are some variations between pre-2005 and post-2005 models due to slight changes in roof contours. Always verify the specific year range listed for each product, as some lights are model-year specific. If your T800 has a custom sleeper or extended cab configuration, you may need to confirm fitment with our customer service team.
How difficult is the installation process, and what tools do I need?
Installation typically takes 2-4 hours depending on your experience level. You'll need a drill with metal bits (usually 3/8" and 1/2"), a center punch, masking tape, silicone sealant, and basic hand tools. The most challenging part is drilling through the cab roof, which requires careful measurement and marking. Many customers recommend using a template or the existing factory holes if converting from OEM lights. Professional installation is suggested if you're not comfortable drilling into your cab.
What's the difference between LED and incandescent cab lights for my T800?
LED cab lights draw significantly less power (typically 0.5 amps vs 2-3 amps for incandescent), last 50,000+ hours compared to 2,000 hours, and provide brighter, more consistent illumination. LEDs also generate less heat, reducing lens discoloration and housing damage. While LED options cost more upfront, they eliminate frequent bulb replacements and reduce alternator load. Most LED cab lights are direct replacements for incandescent units with no wiring modifications needed.
Are these cab lights DOT approved and what about warranty coverage?
Quality aftermarket cab lights should carry DOT certification markings (look for "DOT" stamped on the lens or housing). This certification ensures they meet federal brightness, color, and visibility standards. Warranty coverage varies by manufacturer but typically ranges from 1-3 years for LED lights and 90 days to 1 year for incandescent models. Always check that the lights include proper documentation for roadside inspections.
What styles and finishes are available, and how do they hold up to weather?
Common styles include the classic round "watermelon" lights, rectangular designs, and aerodynamic teardrop shapes. Finish options typically include chrome plastic, polished stainless steel, painted steel, and black powder coat. Chrome plastic is economical but may peel after 2-3 years of sun exposure. Stainless steel offers the best longevity but costs more. Powder-coated options resist rust well but can chip from road debris. All quality cab lights should feature sealed housings with rubber gaskets to prevent water intrusion.
