Truck-Lite’s new Phase 7, 7-inch-round LED light is a completely new design and exceeds DOT requirements for low- and high-beam performance. Using a military-grade, die-cast aluminum housing with a non-yellowing polycarbonate lens, each light houses a dual LED array that is compatible with both 12-volt and 24-volt systems. Solid-state, bulb-free electronics are coated in epoxy, making the lamps impervious to damage from shock and vibration, as well as corrosion or moisture. They use a standard H4, three-blade connector. These lights are made in the USA and come with a three-year limited warranty.
