I put a gfci outlet in my front yard for use during christmas time for lights and such. i ran it to on my front porch light so it only turns on when my front porch light is on. i also added to the gfci a light about 20 feet away so that it lights up a dark area. I turned my breaker on and the gfci works but the light doesn't turn on. why is this happening? Ive tested and reset the gfci. unfortunately it got too dark to work on the wires. what could be the problem as to why there is no light going to the light post?
