Tnlakepanda is correct. It is most likely the electric eye. This lightpost is run by your electricity, so if your home is over a year old, specifically if your closing was more than a year ago it is your responsibility.

This is relatively an easy DIY project if you are comfortable with it. Always turn off your breaker to this post light first. Since your light stays on you should easily know when you turned off the correct breaker.

These cost about $6.00 and usually last around 5-6 years. They have three wires. First take off the top light fixture, being very careful not to drop the fixture or the little holding screws. Then remove the existing electric eye making sure you do not drop the wire leads down the post. Wire it like the existing one and put everything back together.

You can then test this by covering up the electric eye completely with black electrical tape and turning the breaker back on. Understand that it sometimes takes a few minutes for the light to come on, so be a tad patient. Once the light comes back on, remove the tape. It should then go out in a minute or so, then come back on at dusk.

Clean up the light fixture, and consider replacing the old bulb(s) with LED bulb(s). You will save a boatload of money, as regular bulbs cost you about $80 per year in electrical costs.

I'm sure there are youtube videos on this project. If you are not comfortable doing this then by all means hire an Electrician.

Before you do all this, make sure the existing electric eye is unobstructed and clean. I have seen dirty electric eyes do this.....

Good luck...hope this helps! Frank D.
