For sure it was done at compliance , all US models have a 5watt"running light" in the indicator setup
At compliancing it can be "fixed" many ways ,using
A)"Aussie"spec units
B)splitting /driving out a male/female connector in the loom keeping the US unit but only one filament powered
C) Cutting one of the feed wires to the 5watt circuit ( brutal but I have seen it many times !)
Finding US spec globes was difficult here for replacements , until I realised some lamp kits came to Aus with US spec 1157A globes and the HD dealers were binning them. I collected a lamp box full , so I'm OK for donkeys
They don't meet "Aussie specs" apparently
Watch ANY youtube/music video with Harleys taken in the US at night and you'll see the running lights.
I myself like them , think they are a safety plus , and I reconnected my own on my 2008 US import CVO in 2011 as soon as it was WA licensed
