Can I tap off the heated floor thermostat to feed a nearby hallway light?

Thatís what I would do
So just to clarify, I can tap off the floor thermostat (15 amp breaker) for both the bathroom AND hallway lights? Just pigtail the connections in correct?

BTW, how large is the transformer feeding your house and how far away is it?
I don't know. What (or how) would I find this out at?
