We just moved into a split level house about 40 years old. This will be our first Christmas and I cannot figure out how to put up lights because we don't seem to have any outlets outside. I could buy socket adaptor and put it on one of my outside lights but I don't know if this would be safe or not. Suggestions welcome. Not enough time to get an electrician out to put in some outside sockets.

    solar holiday lights would be easiest – Jon Dec 15 '17 at 18:49
  • If you have outlets in your garage, then run the extension cord under the garage door. – Jon Dec 15 '17 at 18:50
  • you can plug a few strings of lights into a socket adapter. You can also run extension cords from garage outlets under the garage door. – agentp Dec 15 '17 at 18:50

    @Jon, solar outdoor lights are dim and pretty terrible in my experience. They might be easy, but not a direct substitute. – JPhi1618 Dec 15 '17 at 19:34
  • You generally want Christmas lights running at times when the sun is not shining. – Harper - Reinstate Monica Dec 16 '17 at 0:55

As long as you don't overload the fixture or the circuit, those socket adapters would be OK, especially for a temporary setup like Christmas lights. The key is making sure you're not overloading anything.

Figure out what else is on the circuit with the outside light, and what size breaker protects that circuit. Figure out what size wire is used inside the light - this will typically be smaller than the #14 used in lighting circuits. Determine the current capacity of that smaller wire, and keep the total load less than that capacity. Using LED bulbs will allow you to run more lights this way.

Of course, using an actual receptacle is the preferred option, so make sure you don't have any outside. Check around the AC unit for a receptacle, and near each entry door. Check in your garage (including on the ceiling, where an opener may be plugged in). Running extension cords all over is quite normal during the holidays.

You may prefer to run an extension cord from inside; just make sure that it isn't crushed when closing the window or door it passes through.

    I took the liberty of emphasizing the critical point here. It's too common that folks rely on breakers for wire protection in these cases, and a 15A breaker is not going to adequately protect 16 or 18 gauge wire with 14.9A of current running to a web of lights. (It's worth noting that stranded wire has a higher capacity than solid, but still....) – isherwood Dec 15 '17 at 18:57
  • I would want to use an extension cord with a GFCI since the light is probably not on a GFCI breaker and outdoor outlets usually are GFCI protected. – Ed Beal Dec 15 '17 at 19:10
  • Those socket adapters (and the sockets, generally) are listed for 660 watts, or 5.5 amps. If you are series stringing Christmas lights, you will find their plugs have fuses, and I'll bet those are 5 amps. – Harper - Reinstate Monica Dec 16 '17 at 0:58
