Product Overview
The Double Fury UltraBurst 9 LED Watermelon Clearance and Marker Light combines primary red illumination with a secondary blue auxiliary function in one compact 1-1/2-inch lamp. Its intense light-burst effect and chrome plastic bezel deliver high visual impact for custom trucks, trailers and other 12V vehicle applications.
The primary red LEDs provide separate low- and high-intensity outputs. Activating the secondary blue function overrides the red illumination for auxiliary, off-road or show use.
Ideal for:
- Semi trucks
- Trailers
- Tow trucks
- Show trucks
- Work trucks
- Custom vehicle builds
Key Features & Benefits
Red and Blue Dual-Color Lighting
Nine dual-color LEDs produce primary red illumination and secondary blue auxiliary illumination from a single compact watermelon light.
Dual-Function Primary Red Output
Separate low- and high-intensity inputs allow the primary red LEDs to support two lighting functions when properly wired.
Secondary Blue Override
When powered, the secondary blue function overrides the primary red illumination, allowing the lamp to change colors without requiring a separate auxiliary light.
UltraBurst Light-Burst Effect
The UltraBurst optical design creates an intense, distinctive light-burst appearance for enhanced visibility and custom styling.
Injection-Molded Polycarbonate Lens
The high-quality, injection-molded polycarbonate lens protects the internal LEDs while allowing the dual-color illumination to remain visible.
Chrome Plastic Bezel
A chrome plastic bezel surrounds the lens, adding a polished accent that complements chrome accessories and custom truck builds.
Epoxy-Sealed Construction
The lamp is epoxy sealed to help prevent moisture intrusion and protect its internal components.
IP67 Water Resistance
IP67-rated construction provides protection against dust and temporary water immersion under the conditions specified by the rating.
Threaded-Stud Installation
The integrated threaded stud and included nylon mounting nut provide straightforward installation through a 3/4-inch-diameter mounting hole.
