Frequently Asked Questions – Watermelon Light Kits

What is a Watermelon Light Kit?

A Watermelon Light Kit is a retrofit package designed to help convert standard 4-inch round light openings into watermelon-style marker lights. Depending on the specific kit, it may include components such as a lens, bezel, bracket, mounting hardware, housing, and LED wiring. These kits are part of our broader full size watermelon lights lineup.

Do these kits fit all trucks?

Most kits are designed around common 4-inch light openings, making them popular for Peterbilt, Kenworth, Freightliner, Volvo, heavy haul trucks, sleeper panels, and custom pickup builds. Fitment can vary by application, mounting location, and kit style, so always review the individual product listing before ordering.

Are these easy to install?

Many watermelon light kits are designed for straightforward installation using common 4-inch openings or retrofit locations. However, installation may require drilling, wiring, cutting, splicing, brackets, or other modifications depending on the truck, mounting location, and kit selected.

Are these kits used on pickups?
