Nilight 7‑Way Trailer Plug Y Splitter — Black 7‑Pin Adapter with Double‑Prong Brass Contacts & Dust Cover

The Nilight 7 Way Trailer Plug Y Pigtail Splitter provides one 7‑pin female input that splits into two 7‑pin male outputs so you can power two trailers or a truck camper and trailer simultaneously.

If you tow a slide‑in camper, a boat trailer, or a second trailer from the same truck, this Y‑style 7‑way adapter makes it simple to share a single factory 7‑pin socket. Built with double‑prong brass contacts, a weather‑resistant plastic housing and a spring‑loaded dust cover, the splitter aims to deliver dependable lighting and auxiliary circuits without rewiring or permanent changes to your vehicle.

How does this splitter let me run lights on two trailers at once?

This adapter plugs into your truck’s existing 7‑pin RV socket and provides two male 7‑pin connectors for separate trailers. It duplicates the vehicle’s lighting and auxiliary circuits so both trailers receive the same signals from a single source.

• One female 7‑pin inlet connects to the truck’s factory socket.
• Two male 7‑pin outlets attach to each trailer or camper plug.
• Supports running tail, brake, turn signals and auxiliary power where applicable.

Will this work with my truck, camper, or boat trailer?

The splitter is compatible with most vehicles that use the standard round 7‑pin RV connector, including half‑ton, 3/4‑ton, one‑ton, and dually trucks, as well as many campers, boat trailers and utility trailers. Confirm your vehicle and trailer connectors are the 7‑pin round type before purchase.

• Fits trucks with a factory 7‑pin round RV socket.
• Designed for common trailer types: campers, boat trailers, utility trailers.
• Useful for slide‑in campers that occupy the bed and require an extra plug.

How durable and weatherproof is the Nilight splitter?

The housing is molded from rugged black plastic and includes a spring‑loaded dust cover to shield the contacts when not in use. Inside, double‑prong brass contact points provide stronger, more reliable electrical mating than single‑prong designs, helping resist corrosion and intermittent connections.

• Double‑prong brass contacts for improved conductivity and durability.
• Sturdy molded housing resists impact and UV exposure.
• Spring‑loaded dust cover helps keep moisture and dirt out of the socket.

Is it hard to install or will it require wiring changes?

Installation is plug‑and‑play — there’s no cutting, splicing, or wiring required. Simply insert the female end into your truck’s 7‑pin socket and connect each trailer to the male ends. This makes it an easy, reversible solution when you need an extra trailer connection.

• No tools or wire modifications necessary.
• Quick connect/disconnect for seasonal or occasional towing setups.
• Ideal alternative to running a separate wiring harness to the side of the bed.

Who is this for? The Nilight 7 Way Trailer Plug Y Pigtail Splitter is aimed at truck owners, RVers and boaters who need to power more than one 7‑pin trailer from a single factory socket. It suits anyone who wants a fast, reversible way to run the lights and auxiliary circuits for a slide‑in camper and a tow trailer, or for towing a double trailer combination without installing extra wiring. If you need a rugged, straightforward 7‑pin splitter with improved contacts and a protective cover, this adapter provides a practical solution.
