well first off congrats on getting your first bp. About a light, no you do not need one but if you decide to use one all you have to do is cut a hole in the top of the tub. Then drill little holes around the big cut out. then get a small piece of steel mesh or metal screen and zip tie it on the inside of the top to cover the hole. then you can set the light right on the metal screen or steel mesh. for other heat i recommend using flex watt heat tape but you will need a thermostat to power it. but I think its way worth it for you and your snake. I used to use the zoo med uth but they always got to hot and they burned a few of my snakes belly's. Now that I use flex watt I have never had a problem. I hope this will help you out some.
