Pack of 5, FVTLED Replacement 2Pin T-Connector Waterproof for Single Color LED Deck Light Kit (5pcs)

The cables attach secure to these connectors. I haven't had a problem with any threading on the connections

Work as expected for adding more lights to string.

Snug fit into each other, almost too tight (serious force needed) !BUT! Verify compatibility before purchase. The top and right connector are what I have (smaller pin with a square key), the left connector is this item (larger pin and v key). These do not work together!! Only thing I could say is o-ring color is how to possibly find compatible parts.

Best of the best and will be back for more.

Hopefully this helps someone with their Christmas lights. These connectors are smaller than normal Christmas lights.

Easy to install

Having these T connectors allowed me to run the WifI (or RF) controller and power adapter from inside my house and once the one cable made it to the outdoor porch, this T split the cable into two. I was able to run about 14 lights to the east porch and 8 to the west. Much much better than running two sets of lights and using 2 controllers. Now one controller runs my entire porch.

As an earlier comment stated only one end cap supplied with the lights the T-connector should also include at least one end cap, electrically they work satifactorily but a big grip is the fact the on the set I have I'm unable to screw the retaining cap of the fixture cord to the T-connector with the result the fixture cord is not captive and can be easily pulled out. Not sure if this is a common fault or just a bad set that I received
