The old trafficators with their little amber bulb are not easy to see for other road users, so to change them into flashing traffficators seems like a good idea. There are several ways to do this, but replacing the little festoon bulb with a modern flashing led must be the eastiest and very effective. These are the "Flashicator" leds I ordered from Classic Dynamo & regulator. I fitted them to the Morris Minor and Austin Ten. As you can see in the video they are bright enough to be visible from some distance away.
