Bought a new hot tub and I cant get the light to work. It is a Hot springs portable. I know the bulb is good and I have even tried using a different one. I dont see any wires I can check or anywhere that I can check a connection. Does anyone have any ideas?

I am a little concerned as to what you are putting the light bulb into, if there are no wires, thus no socket, in which the bulb plugs into. Double check to see if your socket is intact, and verify if voltage is present to that socket.
