Night Cycling question

If there is a low light shining into the tank will that mess up the python's day/night cycling? Also if I use only red light in the tank, since balls can't see the red light, will that affect the day/night cycle since there will never be a change in lighting?

Light levels don't seem to be a huge issue with BP's. Red or infrared bulbs can be used 24/7.

Ok I just wanted to be sure. I'm using a yellow light dimmed almost to nothing on the cool side to bump it up the needed two degrees and a red light on the hot but I'm planning on switching to red in both sides soon.
