      Hi... I'm confused here. Is both connectors of the LED attached to the Photocell and the 3904 post. Or is the Left side of LED post attached only to the 3904 and the Positive (Right) Post of the LED attached only to the Photocell (Left Side Post)??? I can't see it by looking at your photos.

      Please read the actual article for the full description. And, there are no photocells here.
