Yeah, like I said in an earlier post, I've determined these aren't the better quality ones with a socketed bulb. The LED array is permanently soldered in and non-replaceable. I think that's why it's not as bright as with a single superbright LED. When I remove the lense and diffuser, there are three fairly weak micro LEDs in the array. I might look at replacing them all with socketed superbrights eventually. for now, they'll work.

Brew, by running the indicator off the HOT side of the SSR, I'm directly reading the state of the element, not the control. That way, if the SSR fails and fuses the HOT side, I'll know it by the indicator. I'm using industrial control panel mount indicators for a polished look. I'll post pics eventually, but I've been waiting until it's finished so I can avoid the inevitable discussion about how it will never work and I'm about to die.![]()
