Nilight 7-Way Trailer Y Pigtail Splitter Black — Brass Contacts & Dust Cap

Nilight's 7-way Y pigtail splitter turns one 7-pin truck socket into two working 7-pin connections so you can power lights and brakes for two trailers or a trailer plus a slide-in camper at the same time.

This compact, plug-and-play adapter converts a single vehicle 7-way round plug into two male 7-way outlets, giving you a spare connector without adding permanent wiring. Built for towing setups — campers, boat trailers, RVs, and more — the splitter uses brass contact points and a molded housing to maintain consistent electrical contact and protect the connection from dirt and moisture. No cutting, splicing, or tools are required: just plug the female end into your truck’s RV socket and connect up to two trailers or a trailer plus a bed camper.

How does this splitter let me tow two trailers or a trailer plus a camper?

The Nilight Y splitter provides one female 7-pin input and two male 7-pin outputs so you can feed two towing loads from a single vehicle socket. It mirrors the vehicle’s signals — turn, brake, tail, ground, and auxiliary circuits — to both male plugs simultaneously, so both connected trailers receive the same lighting and braking inputs.

• One female 7-way input for the truck’s factory RV socket.
• Two male 7-way outputs to connect two trailers or a trailer and camper.
• Mirrors vehicle lighting and brake signals to both connectors.
• No additional wiring or modifications required.

Is it durable enough for outdoor towing use?

Yes — the splitter uses double-prong brass contacts within the female plug for stronger, more reliable metal-to-metal connection than single-prong designs. The outer shell is molded black plastic with a spring-loaded dust cover that helps shield the pins from rain, snow, and road grime when not in use.

• Brass double-prong contacts for improved conductivity and wear resistance.
• Molded housing resists impact and flex during towing.
• Spring-loaded dust cap helps keep debris and moisture out.
• Compact form factor reduces strain on the vehicle connector.

Will this work with my truck and trailers?

The Nilight splitter is compatible with any vehicle equipped with a standard 7-way round RV socket and with trailers that use 7-pin RV connectors. It’s suitable for half-ton, 3/4-ton, one-ton pickups, long- or short-bed trucks, and dually configurations — essentially any rig with a factory 7-pin outlet.

• Fits standard 7-pin round RV sockets on trucks and RVs.
• Works with trailers, boat trailers, slide-in campers, and RVs using 7-pin plugs.
• Ideal when you need a second connector without running wiring to the truck bed.
• Plug-and-play: no tools, splicing, or electrical work required.

How easy is it to install and remove?

Installation is immediate — insert the female end into your truck’s 7-pin socket, then attach one or two trailer plugs to the male ends. Removal is just as straightforward: unplug both trailer connectors and pull the female end from the vehicle socket. The simple design keeps setup time to a minimum for frequent hookup and storage.

• Plug-and-play design — no cutting or wiring needed.
• Quick connect/disconnect for fast trailer changes.
• Lightweight and compact for easy storage when not in use.
• Single accessory piece: 1x 7-way Y splitter included.

Who is this for? The Nilight 7-way Y pigtail splitter is made for drivers who regularly mix towing and onboard campers — boat owners, slide-in camper users, and anyone who needs two 7-pin connections but prefers a temporary, non-invasive solution over installing additional hardwired sockets. If you want reliable lighting and brake signal distribution to two trailers without rewiring your truck, this splitter is a practical, durable choice.
