Reflectors in the light housings, wire size to lights and ground quality at lights would be my first targets. Wire size to switch and switch quality would be next.

I don't think the flasher was ever a point of concern here, really. Switching to a relay makes it even less of a concern, as it would never be under any significant load.
Switch quality is not a variable, its the factory Delco headlight switch, so my aim was to prolong the life of this switch using inexpensive relays and heavier gauge wiring I already own.
Thinking about it more, and looking at the wiring schematic for the RPO signals offered by GM for 55-59's, only one wire is sent out to the parking lights, so I guess each of those wires changes from a direct 12v power source to a 12v signal wire.
I think perhaps I will leave the front parking lights alone and run them off the switch, and maybe look into a warmer LED bulb option if there is one for the parking/brake housings only.
