The large LED light went out. I have a replacement and I'm having trouble changing it out. My pool builder only left me with about 6" of slack behind the light. I disconnected the wires at the junction box and tied a pull string to the old harness to pull out the old light from the pool side. I can not pull any wire out, it won't budge. I looked to see if there were any clamps, and didn't see any. My pool builder installed it after the pool water was filled. So I don't think he used any sealant. Water came out of the junction box when I took the cover off of it. Probably why the light went out. The light is 10 years old, and the other two still work. Need help on how to pull the old wire harness out.
