Color: Y Splitter Trailer Plug
I recently purchased the Nilight 7 Way Trailer Plug Y Pigtail Splitter, and it has proven to be an invaluable addition to my towing setup. This splitter is well-designed and offers a practical solution for connecting multiple trailers or accessories with ease. The build quality is impressive, with durable materials that feel robust and reliable. The connectors fit securely, ensuring a stable and consistent connection without any wobbling or loose ends. This has given me peace of mind, knowing that my trailer lights and other electrical components will function properly during my travels. Installation was straightforward, thanks to the clear labeling and color-coded wires. It took only a few minutes to set up, and everything worked perfectly right from the start. The Y-splitter design is particularly useful for those who need to connect additional accessories without having to constantly switch plugs. Overall, the Nilight 7 Way Trailer Plug Y Pigtail Splitter is a high-quality product that delivers on its promises. It offers excellent value for money and has made my towing experience much more convenient. I highly recommend it to anyone in need of a reliable and efficient trailer plug splitter. ... show more

Not much to say plug it in and it works. I used it to plug in a brake transmitter while towing RV which was plugged into the other outlet.

  • Good quality
Color: Y Splitter Trailer Plug
I needed this splitter for a specific trailer/rack combination with multiple light setups and it works well so long as you firmly insert the connections. I gave it a four star because the connections need to be really inserted firmly to go in far enough for the latch designed to prevent the connections to slip open to engage. Its a bit of tight fit. But the whole system works and if you need this setup then its a good value. I recommend. ... show more
