We bought this house 6 months ago and the pool light has never worked. We recently replaced the transformer because my electrician said it was the problem. (it was not). So I have a brand new transformer and still need to replace the bulb/entire light. I’m having a hard time finding what I need. My wife wants the light to have a multi color function. What are my options? I appreciate the help. The light in question is pictured below. (roughly 2 inch diameter for the dark circle. Outer circle is probably 3.5 inches) hope that helps.
