Works good
Size: 16AWG -20FT 2Pcs
I used it to set up some extra pods on the back of my truck, and having that full 20 feet of length made it so much easier to route everything cleanly without having to splice in extra wire. The 16-gauge copper feels heavy-duty and is protected by a thick PVC jacket that seems like it’ll hold up well against heat and the elements. It’s a simple plug-and-play setup that saved me a ton of time, and the connections snap together with a really solid, secure click. If you’re doing a custom lighting build on a larger vehicle or a boat, this kit is a total lifesaver for keeping your wiring looking professional and staying reliable.
