Can you piggy back straight from the head light bulbs (plugging piggy back connector in the bulb itself) secondary lights via a switched relay

I seem to remember some car manufacturers did that with certain twin bulb headlamps, just a simple daisy chain from one bulb to another

Might be easier to take the relay positive (the relay switching feed) from a lower powered circuit - I tend to use the instrument illumination bulb circuits, they're somewhat less important.
