International ProStar Cab Lights

Frequently Asked Questions About International ProStar Cab Lights

What are cab lights used for on my International ProStar?

Cab lights, also known as cab marker lights or clearance lights, are mounted along the top of the cab and are used to improve visibility of your truck's height and width to other drivers, especially in low-light or poor weather conditions. They also add a distinctive look to the front of your truck.

Will these cab lights fit my specific International ProStar model year?

Cab light fitment can vary depending on the year and cab configuration of your ProStar, since International made changes to cab styling over the years. Always check the listed fitment details on each product page before ordering, and compare your existing light housings or mounting locations to the specifications shown to confirm a proper fit.

Are these cab lights DOT compliant and legal for road use?

Most cab lights sold for the ProStar are designed to meet DOT requirements for color and visibility, such as amber lights facing forward and red lights facing rearward. That said, requirements can vary by state and by whether the lights are used as functional clearance lights versus purely decorative lighting, so it is a good idea to confirm the intended use and check your local regulations before installation.

What is the difference between the lens colors and housing finishes available?

Cab lights typically come with amber, red, clear, or smoked lenses, and the housings are commonly available in chrome or black finishes. Amber and red lenses are generally used to meet standard clearance light color requirements, while clear and smoked lenses are often paired with colored LED bulbs for a custom look. Chrome housings tend to match factory trim, while black housings give a more blacked-out appearance.

How difficult is it to install cab lights on a ProStar, and do I need any special wiring?

Installation difficulty depends on whether you are replacing existing lights in the same mounting holes or installing a new light bar or bracket setup. Direct replacement lights usually connect to your existing wiring harness, making the swap straightforward with basic tools. If you are adding lights where none existed before, you may need additional wiring, connectors, or a relay, so it helps to review the installation instructions or reach out to our team before starting the job.
