I have the same cam (scout 1) the lights are invisble. You can actually see in a dark room out of the water with the invisble lights turned on. That being said it is intended to be used in Murky water- not for night vision. The spectral lights (red and blue ones) are intended to use in the dark. The scout 1 is about useless once nightfall sets in the water, but its a great cam. When checking if it works , try using it in a dark room, and make sure that light adjustment is turned up by rotating the knob towards more power. Also the green LED display will light up when the light is on. Make sure you check that light when you use it during the day, and dont want the light on, because using it will reduce battery life!
