Been asking a lot of questions lately sorry but just want to be sure on everything and regarding this topic I found a lot of conflicting opinions online.
Maybe the members of here will have more knowledge and experience.

In regards to the night cycle, few questions:

1) I always thought the red light was for us to be able to see them and not disturb the snake. That they couldn't see the light. But now I'm reading that they can see the light? Which is correct?

2) I need to replace my old red light, was thinking maybe going for the blue light, see how that looks in the terrarium. Does that have the same properties as the Red, or any advantages/disadvantages?

Can I go with either one or should I not use one at all. Was also using it to make sure the temp didn't drop too much, they produce a little heat.

Side note, anyone ever use both red and blue together lol, any pictures? Or any pictures in general of your night lights, I think they look really cool.

Thanks
