Brightfour T Tap Wire Connectors for 16-20 AWG Wires, No Wire Stripping Low Voltage Wire Splice Connectors, Solderless 3 Way 1 Pin 12 Pack

They work so much better than those blue connectors! Avoids doing damage to factory wiring.

I used these to wire my boat trailer. Worked well.

I liked the 3-way design but it is too small for my 14 gage cable. The lid won't snap closed even with slip joint pliers.

I chose these connectors over the colored plastic ones because they are higher quality. They are very easy to use and so far the quality of the connection has been perfect

Great product. Clever 1 unit for 2 wires.Bad packaging ziplock bag .thrown in with a other item ordered. Banged around in larger bag amazon shiped in. 1/2 of the connectors closed up.

I bought these to keep in my mobile repair kit. I would never consider these to be as good as a real crimped connection, but for an unplanned repair I used them and they worked perfect.

I read reviews about these and there were several that said 14 & 16 gauge wire would not work. These will be used for outdoor LED pathway lights with a maximum of 4 lights on the string. Calculations said that 18 gauge would be more than sufficient for the current load with minimal voltage loss at the last light of the string. Well they don't mention either the diameter of the hole in the connector or the maximum outside diameter of the wire that can be used. I measured the diameter of the hole in the connector as 3.03mm and the OD of the wire I purchased measured 3.4mm +/- a couple of hundredths.It appears to me that the wire sheathing diameter is not a standard so the diameter becomes important and when searching for 18 gauge wire but I never saw any mention of it during the wire search.I was able to get the first/trial light to illuminate by using a set of vise grips to squeeze the connector but as soon as I released the pressure the light went out. The connector clips never engaged.Just a heads up.Update 6/27/25: I found some 18 GA wire locally and the sheathing OD was less than 3mm, being local I could measure it. Got it home and started wiring again from scratch. Got the first light to work but not so the second. Long story short the idea behind the connector is good, exactly what I needed but but execution is a total failure. Ended going to the tried and true method of wire nuts. More of a pita but they all work.

First time using these to put lights up in a storage trailer. They made installation easy.
