Used as replacements in old building.....but these are larger than the old sockets so I had to cut down the plastic at each end (pain in the Azz) probably perfect for newer construction

the "button" at the bottom is quite small. When I screwed it into my old socket, it did not make contact. I found that the socket had been used for many years with bulbs that had deformed the socket's springy inner contact.  This was tedious to fix.  After triple-checking that the electricity was OFF, I used needlenoses to pull the spring up in the socket. This fixed the problem but turned a 2-minute job into a 30-minute job.

Giving it 5 stars if you intend to use this product as advertised. In my case I am using this horizontally and the larger of the two prongs is facing the wrong way for me to orientate the switch as I need. I took it apart and thankfully the larger size plug came out with ease, I took a Dremel to it and reduced as needed. This in-turn broke the "weld" holding the two pieces together, thankfully I was able to pinch them together and slide them back into the molding as needed. I wouldn't recommend this but hey it's like you pulled permit to plug something into your outlet right?

The diameter of the socket extension is about an inch making deep well nuts nearly impossible to get. Had to switch to my crescent wrench when working on lawn mower engine as they were to large to get the carburetor off. Otherwise very happy with them.

nice tool.  Main hole diameter is too big for my universal plasma torche.  will require some mods to make it work for my 0.8 diameter plasma head.

I'm using a higher grade speaker wire, and it really was a little bigger gauge wire than what the terminals are designed for.

The holes in the back where the light socket plugs in, had to be shaved so that it would fit.

I only used the 19mm socket from this set. Over time the plastic falls off but it slips right back on.

Functions perfectly.  It turned out to have an outside diameter too large for the recessed jack for which I got it, but whittling down the plastic body enough to get the job done was a snap.

I actually had to grind the flared end of the bayonet to get these lights to go into the socket.

I just realized that the socket I received is not the one shown in the picture.  The one I received steps down to a smaller diameter on the working end.  That's no problem at all but I just thought I would mention it so someone thinking about buying this is aware of this. The tool would be slightly weaker than one that doesn't step down but this should be no issue in use. It appears to be very well-made and I have confidence that it will last virtually forever.

We had to cut the metal to make them fit, even though the inches listed were compatable with the specification.

It was a little longer than what I had wanted, and I have had a couple of them crack around the plug.

bought to replace old ones maybe 20 years old. These are nice bit the mounting holes are spaced differently and that is a downer unless you use these for new work. Also these plugs/sockets are polarized ( the pins are different sizes) and the old ones had pins of the same size. Not a problem and probably better the new way. In my case I only needed a replacement socket and then ended up replacing both plug and socket for a better job.

nice assortment of sockets, i needed some uneven number of sockets and was able to cut these down to fit.

The connectors that came with one of my sets of wire cubes kept breaking, so I bought these connectors to replace the bad ones. While these connectors are much sturdier than my old ones, they are the wrong size. I have two different sets of wire cubes with different size wires, and these connectors are too big for either of them. I did manage to make them work though by wrapping electrical tape around the wires. Of course, now my one good set of old connectors don't fit over the tape.

These lights do not fit in standard, un-modified, GM, plastic sockets. I had to modify the sockets using a tapered rotary stone in my electric drill. The inside tops of the sockets need to be shaved down a bit. Once this is done they work fine.
