"Ease of troubleshooting for photcells:"

Here's a way to ease the task of replacing bulbs or doing maintenance on site that is controlled by photocells. Instead of covering the photocell to test lights, you can wire in a test switch in parallel to override the controls. This saves time of working with the photocell (waiting for it to activate or deactivate), is inexpensive to install, and easy to do. You can use a key-operated switch for security, if needed.
