Is shower stall ceiling lighting required in a new renovation shower?

Is it necessary to have an overhead light in a shower stall when there is adequate lighting in room itself? I have 3 bathroom 2 with full tubs one has an overhead light , one does not. Shower used to have one but it is too old to resurrect and I see no reason to replace. Room is well light and has a large window. NJ is locale Thank you

The only time you need a light in your shower is if you decide you don't have enough light.
