Designed for weld or bolt installation, the assembly replaces flimsy plastic housings and centralizes stop\/turn\/tail and side-marker functions into a single steel unit that fits rear, side, bottom or top frame positions.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the kit simplify trailer light mounting?\u003c\/h3\u003e\n\u003cp\u003eThe weld-on box is pre-cut to accept a 6\" oval tail light, a 2\" round side light and a license plate, so you won’t need to fabricate custom openings. It installs directly onto tubing or plate frames via welding or bolting, which speeds up fitting and produces a tidy, secure finish.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePre-cut openings for 6\" oval tail and 2\" round side marker\u003c\/li\u003e\n  \u003cli\u003eWeld-ready steel box fits rear, side, bottom or top frame\u003c\/li\u003e\n  \u003cli\u003eLicense plate mounting provision included\u003c\/li\u003e\n  \u003cli\u003eOption to bolt on if welding isn’t preferred\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes the light and housing durable outdoors?\u003c\/h3\u003e\n\u003cp\u003eThe housing is formed from heavy-gauge steel and finished with a black powder coat to resist corrosion and chipping.

Color-coded wires simplify hookup: white is ground (with an O-ring terminal), black runs the tail\/marker circuit, and red handles the stop\/turn circuit.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRed wire: stop and turn signal input\u003c\/li\u003e\n  \u003cli\u003eBlack wire: tail and side-marker circuit\u003c\/li\u003e\n  \u003cli\u003eWhite wire with O-ring terminal: dedicated ground\u003c\/li\u003e\n  \u003cli\u003eStandard 3-wire layout fits most trailer harnesses\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this kit fit my trailer and lighting needs?\u003c\/h3\u003e\n\u003cp\u003eThe box is sized and laid out to accommodate common trailer frames and 6\" oval LEDs used on many utility, cargo and boat trailers. Because it can be welded or bolted in multiple orientations (rear, side, bottom, top), it adapts to different mounting locations and retrofit projects without major modification.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUniversal fit for trailers using 6\" oval tail lights\u003c\/li\u003e\n  \u003cli\u003eMultiple mounting orientations for flexible placement\u003c\/li\u003e\n  \u003cli\u003eWorks for new builds and upgrades to existing trailers\u003c\/li\u003e\n  \u003cli\u003eCompact footprint keeps lights protected and out of the way\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: This Nilight Weld-On Trailer Light Box Kit is aimed at DIYers, fabricators and professional trailer builders who want a stronger, more weatherproof rear lighting solution.
