srownin Posted April 16, 2010 Author Share Posted April 16, 2010 Very silly issue. When we first got the house, the lights in the garage went on when I walk in front of them. After the first light buld change it stopped working. I have found what I thought were the instructions but they don't seem to work. Basically, the directions I saw told me to turn the light off and then press and hold the button for 10 seconds. Didn't work. Any thoughts? Thanks,Scott Link to comment Share on other sites More sharing options...
