Designed for direct welding to trailer frames, the set arrives ready to accept lights via rubber grommets and simple pigtail wiring. The components are IP65-rated for water resistance and built to replace fragile plastic housings commonly used on small commercial and utility trailers.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the welded steel housing improve trailer lighting durability?\u003c\/h3\u003e\n\u003cp\u003eThe steel boxes are formed from heavy-duty carbon steel and finished in a black powder coat that resists rust and chipping. Welding the boxes to the trailer frame produces a permanent mount that won’t shift or crack like plastic housings when exposed to road vibration or cargo impacts.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbon-steel construction for impact resistance and rigidity\u003c\/li\u003e\n  \u003cli\u003eDurable black powder-coating protects against corrosion\u003c\/li\u003e\n  \u003cli\u003eWeld-on design prevents loosening and reduces maintenance\u003c\/li\u003e\n  \u003cli\u003eRubber grommets seal the light assemblies and block moisture ingress\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat lighting performance can I expect from the 6\" oval and 2\" round LEDs?\u003c\/h3\u003e\n\u003cp\u003eThe kit’s 6\" oval tail lights use multiple high-efficiency diodes with pearl-shaped reflectors to create broad, uniform illumination for brake, tail, and turn functions.
