Traffic Signals installed that have never been activated

Here's a signal that's been in flash mode for probably a long time in Brooklynn, Michigan, at the US-12 entrance for the MI International Speedway: https://www.google.com/maps/@42.0581373,-84.2471049,3a,24.8y,248.55h,96.99t/data=!3m6!1e1!3m4!1sHpjj9jm9Jjzv9Q_rJESPtQ!2e0!7i13312!8i6656

Crosswalk signal on the Interurban Trail in Kent, WA left in yellow flash and never activated.  Over the years, the pedestrian heads were vandalized away.  The signal a block to the north has been activated.

The traffic signal at the end of the would-be Schuylkill Parkway near Norristown have been in flash mode presumably since the intersection was built, with a stop sign put up for Valley Forge Road. Was this signal ever fully operational?

That's only the second example of this setup that I know of in WA (the first being in Tacoma, which I posted on page 1).

There's only two that I know of around here.  CT 159 @ Lawnacre Rd, Windsor Locks, and SR 541 @ Tunnel Rd, Vernon. Both lights are/were left in their flashing phases. The latter signal was replaced with single flashing elements c. 2014.

There is also a single FYB on Avery St. in South Windsor that I have never seen lighted up. It warns of a steep grade. I think it's actually privately owned. The control box is on a utility pole next to a mailbox.
