On the _STOCK_ 1970 SPL, the headlamps are fed from two separate fuses, 
HL and HR, 10A each.
Highly unlikely that they have both failed but check the integrity of 
them anyway.
The Headlamps relay provides the _ground_ for both low and high beams 
depending on the position of the Light Switch.
Have you lost both High and Low beams?
I would check the relay connections first to confirm ground applied to 
the two Red/Yellow wires from the Light Switch.
The relay at rest should switch the ground to the Low beams from the switch.
If you don't see a ground on the relay terminals then you may have a 
faulty switch on the dash.
