Having problems with two prong christmas lights adapting to two prong extension cords... help?

It would help if you tell us what the problem is, but ?I'll chance a reply.

If the problem is that one of the plugs is to large for either receptacle hole on the extension cord, then the solution is to purchase "Polarized" extension cords.

Those receptacles on the Christmas lights are designed to only fit Christmas light sets, not extension cords. You are better off to plan ahead with your lighting design. The UL listing of the sets only allows their use with other sets. The design is made to protect the manufacturer, and make it difficult to use any other polarized plug.

You can not plug extension cords into christmas lights, only other christmas lights

I used to grind down the wider blade on my extension cords for this very reason. Or I would take dead strings of lights, pull out all the bulbs, and use them as Christmas-light-extension cords.

My Christmas displays were great though, I won awards!

Can you further explain "you can not plug extention cords into christmas lights, only other christmas lights
" I am having trouble picturing this in my minds eye.

Simple the plug on the extenstion cords are too large to fit into christmas lights female plugs.

While by merely a quick look it would seem like they would but they will not fit.

I did the same at one point of cutting or grinding the power cords down to fit into the christmas lights, but stopped that and went to a better layout of cords.

Backwards?

You plug the Christmas lights into the extension cord. From there you plug the next set of lights into the current set of light's receptacle.

In my guess, I was thinking more along the lines of outside lights, not just tree lights.

Please note that the original poster has yet to reply and tell us what the failure actually is.

Probably never noticed the extension cord thing because most of my household cords are not polarized, they do fit on each end of my lights, I am cheap.

Ballengerb... time to throw out those cords

[ballengerb1]

LOL never throw out what is still working. I know a polarized cords provides more safety but I'm 61 and never run into any problems. What safety faults exist if I continue to use non-polarized extension cords?
