We are renovating our main bathroom and are wanting to put a 3 piece fiberglass tub in that has the roof as well.
Can you put a light in this enclosure and if so, can we run it off the main light in the bathroom?
As Adrian stated, yes it can be done if it is rated properly. In addition, if it is in contact with insulation it must be insulation contact (IC) rated. If it is not, the light must be boxed so it is not in contact with the insulation.
It can be connected to the existing fixture in the bathroom if it does not violate the codes that relate to the total number of devices on a circuit or the total wattage allowed on the circuit.

You did not mention what type of light you were installing, surface mounted or recessed. Surface mounting fixture does not require an "IC" (insulated ceiling) box but it does require a vapour barrier to prevent moisture from leaking into the attic space. If it is a recessed style fixture (pot light), it must be rated for IC use and it MUST have a "vapour tight" trim that seals vapour from getting into the box. Adding it onto existing wire must be to caode (as mentioned) with regards to maximum loads on circuit, mixing aluminum and copper, etc etc. If there is a fan inside the fixture, it must be GFCI protected and approved for use within show enclosures.
