The trouble is I want to compare 2kHz+ from one light with 2kHz+ from
a neighbouring light and see if they're in sync.

Maybe use a dual trace oscilloscope?

And you'd have to isolate the lights from each other.

Since this landed in alt.home.repair, I gotta ask.* Do you have
single-phase or two-phase?

Normally, neighboring lights would be powered from the same phase.
