Which light is it?
The camera has three LED lamps on the front:
1. The status indicator, which is bottom center on the camera face. This one is controlled by the LED setting and will be either red or green depending on status.
2. The WPS indicator, which is bottom right on the camera face. As far as I know, this one will only be on if you press the WPS button on the back of the camera; it is blue when lit.
3. The night-vision lamp, which is center right on the camera face. This will come on depending on your settings for IR illumination, and is red.
