Are we talking side markers or side indicators? Where I am, side markers are right in front of the leading edge of the door, like Porsche, Saab, etc. This was the big thing back in the days before the import craze. Ahhh, I remember hunting the parking lots (not junk yards) for those Saabs.
I was thinking of adding these to the Z, but am debating...they are pretty played out border line cool. But safe nonetheless!
There WAS a way to make the lites blink alternately from the turn signals, can't remember though...
