Review on JACKYLED PBC RGB LED Light Strip Connectors - 🔌 10 Pack 4-Pin Solderless Adapter for 5050 Multicolor LED Tape Lights by Gallo Carone

Works great. I've used it on two different lanes. It is important that the strips are aligned as shown in the picture. All four wires should be under the four metal lines in the connectors on either side. If not, it doesn't light up. Check immediately after connecting, plug it in to make sure it works properly on all colors. Make sure the sticky backing is stuck to the connector. This will help, but don't rely on it to keep it from moving. Don't stress it while attaching it to the wall or it will move in the connector so I pressed the strip against the wall on both sides and then pressed it last rather than tightening the loose end when I press it against the wall If it is an undamaged strip, the connector is released. ALSO it may move while you are trying to install it. So after you've hung it on the wall, you should test it out before fully mounting it on the wall by lifting the doors and making sure the cables are properly seated inside. If specific colors don't work, your wires are misaligned. Open the plug and plug it back in. Always cut the LED strip on the copper part where the little scissors symbol is, otherwise it won't shine past the last copper wire (lesson learned. Works great for me).
