The included 25-foot wishbone harness runs the full length of your trailer and connects to your tow vehicle's standard 4-pin or 5-wire connector. Both tail lights use a \u003cstrong\u003eself-grounding design\u003c\/strong\u003e — ground is made through the mounting studs, eliminating the need for a separate ground wire.\u003c\/p\u003e\n\u003cp\u003eTypical wiring connections via the included harness:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrown\u003c\/strong\u003e → Tail \/ running lights\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYellow\u003c\/strong\u003e → Left stop \/ turn signal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGreen\u003c\/strong\u003e → Right stop \/ turn signal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhite\u003c\/strong\u003e → Ground (harness ground to vehicle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlack\u003c\/strong\u003e → License plate light (driver side)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe two amber J-5735-SA marker lamps mount on the front corners of the trailer and connect to the brown running light circuit.

The J-20445-KCD includes both tail lights, two amber marker lamps, a 25-foot wishbone wiring harness, license plate bracket, wire connectors, and all mounting hardware. For most trailer rewiring jobs, this is everything you need.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the lights truly submersible?\u003c\/strong\u003e\u003cbr\u003eYes. Both the J-20445 and J-20445-L use a gasketed bell-jar sealed housing rated for full water immersion — including repeated dunking at the boat ramp and saltwater exposure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat size trailers is this kit designed for?\u003c\/strong\u003e\u003cbr\u003eThis kit is specifically designed for \u003cstrong\u003etrailers over 80 inches wide\u003c\/strong\u003e, which are required by federal law to have rear clearance lights, side marker lights, and a DOT-compliant tail lighting system. The 7-function combination lights satisfy all of these requirements in a single unit per side.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this replace my existing Peterson or Optronics square lights?\u003c\/strong\u003e\u003cbr\u003eIn most cases, yes — as long as your current lights use a 4-inch square housing with 2-bolt \/ 2\" center mount. Measure your existing light footprint and stud spacing to confirm before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between this and the J-75 \/ J-75L lights?\u003c\/strong\u003e\u003cbr\u003eThe J-20445 series uses a \u003cstrong\u003e4-inch square bell-jar housing\u003c\/strong\u003e, while the J-75 \/ J-75L use an \u003cstrong\u003e8-inch rectangular housing\u003c\/strong\u003e. Both are submersible over-80\" trailer lights — the difference is the mount style and housing shape. Check your existing lights to determine which fits your trailer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this kit DOT legal?\u003c\/strong\u003e\u003cbr\u003eYes. All lights in the J-20445-KCD are DOT and SAE approved, meeting FMVSS-108 requirements for stop, turn, tail, clearance, marker, and license plate illumination.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQuestions?\u003c\/strong\u003e Call or text AAA Trailer at \u003cstrong\u003e517-225-1991\u003c\/strong\u003e — we'll confirm this is the right kit for your trailer before you order.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e📞 Call\/Text: 517-225-1991 🌐 AAATrailer.com\u003c\/strong\u003e\u003c\/p\u003e","brand":"Crystal","offers":[{"title":"Default Title","offer_id":50581064581429,"sku":"J-20445-KCD","price":62.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/9144\/0181\/files\/jammy-j20445-kcd-led-trailer-light-kit-submersible.jpg?v=1773772293","url":"https:\/\/aaatrailer.com\/products\/jammy-j20445-kcd-led-trailer-light-kit","provider":"AAA Trailer","version":"1.0","type":"link"}
