Product Overview
Sometimes a product doesn’t pass every quality test — but still deserves a second chance.
This Amber/Blue Watermelon LED Marker Light combines the classic 3.5″ watermelon cab light design with a dual-color LED system that lets you switch between amber and blue illumination depending on your wiring setup.
It’s bold, colorful, and occasionally unpredictable — but at this price, that’s part of the deal.
