Kenworth T700 Cab Lights

Frequently Asked Questions About Kenworth T700 Cab Lights

Will these cab lights fit my Kenworth T700 without modification?

Cab lights designed for the Kenworth T700 are built to match the factory mounting locations and hole patterns on the cab roof and marker light panels, so most kits install using the existing mounting points. That said, it is always a good idea to compare bolt patterns and connector types with your specific truck's year and configuration before ordering, since minor production changes can occur over the years.

Are these lights DOT compliant for use on the road?

Many cab and clearance lights sold for the T700 are designed to meet DOT and FMVSS 108 requirements for marker and identification lighting, but compliance can vary by manufacturer and light color. Check the product listing or packaging for DOT certification markings, and make sure any replacement lights match the required color pattern (amber up front, red at the rear) to stay street legal.

What is the difference between LED and incandescent cab lights?

LED cab lights draw less power, run cooler, and typically last significantly longer than incandescent bulbs, which makes them a popular upgrade for drivers looking to reduce maintenance and electrical load. Incandescent lights are usually less expensive upfront but will need bulb replacements more often over time.

How do I wire and install replacement cab lights?

Most cab light kits use a simple two-wire connection that ties into your existing marker light wiring harness, so installation generally involves removing the old light, disconnecting the wiring, and connecting the new light using the same connectors or basic butt splices. Always disconnect the battery before working on the wiring, and test each light before reassembling any panels or trim.

What finish and lens color options are available?

Cab lights for the T700 typically come with clear, amber, or smoked lenses, and housings are usually chrome or black to match the truck's trim. Choosing a lens color that matches your local lighting regulations and the rest of your truck's marker lights will help maintain a consistent look and keep you compliant.
