[TR] signals don't work

Just for clarity, the answer to this depends on the vintage of your car (and
what changes have been made by previous owners).

Until TS18912, the turn signals were on the corners (along with the tail
lights), and the center lamp served as both brake light and license plate
light.  At TS18913, two more "beehive" style lamps were added to serve as
turn signals, and the corner lamps changed to being brake and tail lights.
The center lamp got a chrome cover and served only as license plate light.

As with most change points, those numbers are only approximate.  There may
have been some cars on either side of the line, with the other configuration
(cars were rarely finished in commission number order).  And no doubt there
are a few earlier cars around that have had the beehive turn signals added
after leaving the factory.  There was even a factory plinth available to
give a flat mounting surface (which the factory used on a few cars just
after the change, so they could use up the earlier rear aprons).
