Well I went outside with a trash bag and a hammer.  I needed to pull the old ones out and drive the new ones in. I did it!  I was anxious to see them light up my driveway that night. They didn’t work!  Darkness!  I went back in my house ready to send them back but by chance I read the book that was tucked in the box. Ha!  It said be sure to switch the lights on. The next morning I switched each one on and voila!  I have a beautifully lit up driveway.  I guess it pays to read the directions first.
