I don't recall them clicking when you turn the key ON, but I believe you. Those 
flashers had a few "quirks." My 68 clicked every time I hit the brake pedal. 
Eventually I fixed this by resoldering a bad connection, I think. Or maybe it 
was just a bad capacitor that I never fixed.... I think it's all related to 
voltage transients in the 12V power, which this design is sensitive to.

I don't think they all did this, nor did they do it when new. Russ may remember 
something about these, too.

It's been a long time, but I think the flasher click might be a quick double-
click, and it's probably a softer click than the FI relay.

Nope, it's a good point, and I hadn't thought of it.

And now we've managed, once again, to mention the FI double relay clicks twice 
today.  ;-)
