Yeah, it's a wonder how all those antique bikes and cars ran for years without modern rubber insulating boots.
And They are super Trick...and fun to look at. I would Not ride in the rain with them... Once apon a Time..I was riding My '74, in the Rain, not knowing I had a poor spark plug Cap, or Wire, or??.. Lucky Me...got Zapped, right in the Gonads...Really Pleasant Experience!!!

I’m not trying to be negative Nancy or look down on the visual appeal. I just don’t want the guy to be unexpectedly broke down. Yep they did them in the past that way as you say… asK yourself why did they change? Why don’t they still do it that way?
Take a good look at the connectors pictured. Look real close. do you think the metal quality is as heavy, thick and full of copper as the ones from a 80 to a hundred years ago? Or do these look gimmicky for a trick look in the chopper world? Do they look Temu, with pop riveted ends into thin inferior low conducting metal?
When something like that was original it was 6 volt. Weak coils.. and they just hadn’t learned a better way yet. This is going on a 12 volt with a much more powerful modern coil…. The demand from a EVO motor on ignition compared to hundred year old 6 volt low compression engines…. Doing the math are you?
The aftermarket does all kinds of things to look cool… doesn’t mean it’s a good idea. Hyper-charger? Upswept and side swept Delortos? Upswept Dragonman fishtails? Chain driven open primaries? Jockey shifters? Lots of crazy personalized fabricated stuff for looks…how much of it is practical, reliable or adds performance… how much of it destroys performance?
Wish The OP all the best. Hope it looks cool and runs well enough. I wouldn’t be kind or helpful if I kept quiet and didn’t mention any of the risk.

I'm with you, but I hated seeing the guy's vision being beaten down. Lowbrow does make quality parts, many in the USA, so I suspect these will hold up. As far as voltage demands, as long as the conductor has good contact to the ferrule, it looks OK to me. Anyone want a hypercharger? My springer came with one, and I'm not going to be using it. LOL
I run Autolite on my Flathead, the cap comes off for installation like the OP is requesting. Here they are on my 1946, been running them like that for 10 years in all kinds of weather and conditions including hours of heavy rain, no issues. I never tried touching them when the bike is running, seemed like a dumb thing to do, last picture is Michigan or Indiana in some serios Ohio Valley rain, because it always rains there.
