I think the strut mounted indicators really clean up the rear end. Kuryakyn make a kit for the HD softail that has hollowed out stauntions that act as bolts to the trim and as conduits for the wiring. I have'nt been bothered by the Police here in Perth...they're generally not to worried about old guys on cruisers, they're too busy worrying about 1%ers and transformers do stunt shows for speed cameras. As far as Safety goes...I'm more worried about knuckleheads seeing them more than figuring out which way i'm headed. These indicators are really and I mean really bright. Do it...
