Well Smily it has been 14 months and 2 weeks since you promised photos...should I give up waiting??
Thanks Brett you come thru again!
(You might want to edit away the ebay link which has long ago gone invalid).
For the life of me I cant see what the cover did nor why it was necessary.
What about the clear button or "knob" that Smily mentioned? It apparently is at the lamp end of the "circuit" and maybe magnifies the initial output??
Andy you did not answer whether that part is still available.
My 74 has the indicators but no mention that I find in the service manual.
Were these options or standard?
What years had these? I know 71-77 from posters in the other thread*.
Why were they discontinued ? Seems like a very useful tool.
I suppose they only monitored the tail lamps not the brake lights...correct?

Another thread concerning these indicators
is mistakenly titled LEDs. (See link above in another post).
