Ho-ho-ho…Merrrrrrrry Glaremas!

The right way to do it is to create a contour signature. The message you're trying to convey isn't "Notice this blob of light/this blinking light over here". The message you want to send is "This is a motorcycle, and this is its position and direction of travel". With that information, other drivers are not only significantly more likely to effectively see you, but are also more likely to make appropriate gap-acceptance decisions rather than screwing that up and turning across your lane smack in front of you (one of the more common types of car/motorcycle collision).

What do we need to do to get the legislators and regulators to make some kind of federal level change here in the US and in Canada?

It seems like this problem is not only in the USA.

I still run the older Halogen sealed beams on our 75 Dart. Compared to everyone else out there on the road, these are so weak that I'm constantly re-checking to see if my lights are really on!!! 13.4 volts on the system, too.

Dan, I ran across these

Those are straight from somewhere in the middle of the mountain of fraudulent, unsafe garbage on the market. The ratio of junk to good stuff is enormous. Just disregard anything that was not made by one of the relatively few legitimate lighting suppliers—the ones who make lights for automakers. Some of their aftermarket stuff is good, and that's where there's discussion worth having.

Disregard anything—literally: everything—else. All the alphabet-soup brands on Amazon, the generic crap on eBay, the bullshіt marketing brands ("Octane", "Dapper", "Delta"), the hot rod/T-bucket/chrome shop house brands…every last little bit of it is rubbish without even a smidge of merit.

There is exactly one legitimate 7-inch round headlamp with a built-in turn signal on the market; it's this one. Cool multifunction packaging, but I don't count the low/high beams among the best. Some months from now that (American) maker will be introducing a whole range of all-new, better and less expensive LED sealed beams, including ones with inbuilt turn signal.

I have also noticed that a lot of newer cars turn off the headlamp when the turn signal is on

Headlamps, no. Daytime running lights, yes. If you see someone's left light turn off when the left turn signal goes on at night, it's because they've failed to turn on their (nighttime) headlamps.
