If the driving lights have one wire for white, a second wire for yellow and a ground(common/earth), you don’t need anything else to accomplish the task. Just run a wire from the second (yellow inout) wire to each of your indicators.
That is true. It does, however, add a layer of marksmanship to remember to have your low beam on when turning.
The Blinker Genie, which I usually use on the rear to make the indicators serve as rear running lights. The blink by shutting them off to create the "blink". I
think the device can be used also switch the driving lights to yellow and bling without regard to the headlight setting. Obviously, I haven't employed one for this arrangement yet. I thought I'd let you sort it out.
It is an off-label application but I'm sure enough to say it publicly.
