[TR] TR3A turn indictors

Sounds to me like a flasher problem.  Some of the flashers being sold as
suitable for our cars don't work right.

To double-check, temporarily connect an unpowered test lamp (or voltmeter)
between the center terminal of the flasher and ground.  Turn on the key,
turn on the turn signals, the test lamp should act exactly the same as the
dash lamp.  If so, the flasher is the problem.

One solution is to buy a Tridon EL13 'electronic' flasher, which does work
correctly (although it looks rather out of place under the hood).

What I eventually did on my TR3A to solve the issue was to modify the
original wiring, by disconnecting the ground from the indicator lamp, and
moving it to a source of switched voltage (the green wire on the fuel
gauge).

Hopefully, TRF and Moss are selling flashers that do work right without the
modified wiring, but the ones sold by Kragen and Pep Boys would not work
without the mod.
