[Mart]

Here I'm running those bulbs on the front, and all red lamps on the back, but with separate bulbs for brakes and indicator. So no fancy relays or switches.

It sounds like your lighting regs are a bit tighter than here in the UK. On such an old vehicle no hazard flashers would be expected. To be honest, I never really thought about it. The same bulbs are available in clear if need be.

Mart.
