Frequently Asked Questions About Kenworth T880 Cab Lights

Will these cab lights fit my specific year model T880, and are there any differences between model years?

Most aftermarket cab lights are designed to fit Kenworth T880 models from 2013 to present. However, there are subtle differences in mounting hole patterns between early models (2013-2016) and newer versions (2017+). Always verify the specific part number matches your truck's VIN year. Some lights require different mounting brackets for day cab versus sleeper configurations, so double-check your cab style before ordering.

What tools and experience level do I need to install cab lights on my T880?

Installation typically requires basic hand tools including a drill with metal bits, wire strippers, crimping tools, and a multimeter. Most installations take 2-4 hours depending on whether you're replacing existing lights or adding new ones. If drilling new holes, you'll need a template or careful measurements to ensure proper spacing. Basic electrical knowledge is helpful for wiring into the existing clearance light circuit. Many drivers successfully complete this as a weekend project, though professional installation runs $150-300 if you prefer.

What's the difference between LED and incandescent options, and which holds up better?

LED cab lights typically last 50,000+ hours compared to 2,000-5,000 hours for incandescent bulbs. LEDs draw about 80% less power, reducing strain on your electrical system. In terms of durability, LED units with polycarbonate lenses handle vibration and weather better than glass incandescent lights. While LEDs cost more upfront ($30-60 per light vs $15-25), most drivers report they pay for themselves within a year through reduced replacements and lower power consumption.

Do aftermarket cab lights meet DOT requirements, and will they pass inspection?

Quality aftermarket cab lights that are DOT approved will have clear SAE/DOT markings on the lens. Federal regulations require amber clearance lights on the front and sides, with red permitted on the rear. Lights must be visible from 500 feet away. Avoid cheap imports without proper certifications, as these can fail inspection and result in fines. Stick with established brands like Grote, Peterson, or Maxxima that specifically state DOT compliance in their specifications.

What style options are available, and how do I match my existing lights?

Common styles include the classic round 2-inch lights, rectangular LED bars, and teardrop-shaped designs. Most T880s come factory-equipped with either chrome plastic or smoked lens styles. For the cleanest look, match your existing marker light style - if you have round amber markers, stick with round cab lights. Popular finishes include chrome bezels, black powder-coated housings, and clear or smoked lenses. Many drivers prefer the modern LED light bars for better visibility, though traditional round lights maintain the classic truck appearance.
