If you tap a 240V lamp off the switched SSR hot line and the other hot line and have no element plugged in, it will light up due to leakage.

If you tap a 240V lamp off the switched SSR hot line and the other hot line, and have the element plugged in, it will only light up when the element is actually firing (leakage current will almost all go through the element since it is MUCH lower resistance than the light).
best explanation so far! thanks walker

Doesn't matter whether the SSR is or is not firing. It will light up all the time.
