Should I turn the lights on, and is she ready to breed?

[ShadowLatios]

I have a female argentine black and white tegu who’s roughly 3-4 years old (I wasn’t her first owner) and late in November she barely began coming up so I started cutting back on how long the lights were on for. Eventually, there were no light for about a week or two and she only came up for 5-10 minutes everyday or not at all. Today she came out today, walked around for a while, and I don’t know if I should turn the lights on. I really want to breed her to my friends male, and she’s great size and everything, I’m just wondering if the timing is right.
