Spa Light apparently leaking. Where can I find replacement parts? Gaskets, Housing, Etc

I just bought a house with a pool and spa. When I tried to turn the pool/spa lights for the first time the breaker tripped. I took the light out of the spa and took is apart. Sure enough there was some light condenstation on the inside of the light. The gasket was somewhat worn as well. I cleaned the gasket and dried out the LED’s. Put everything back together and got the lights to work without tripping the breaker. Worked great for a month until one day I turned on the light and the spa light went out. No breaker tripped and the pool side light stayed on. So now Im worried that water creeped back into the spa side light. Can someone tell me where I could go to order the new plastic housing and new gasket for this light?
