Driving lights power source in an L320

[Aussie Jeepster]

I'm currently in Cairns on holiday and am working out how to wire up a couple of Rigid Industry LED driving lights on my RRS. (Its in Adelaide!).
I'm wondering where to pick up the feed for the switch for the relay?
Is it worth pulling the headlight to find a wire for hi beam (which one?) or is there a fuse in the fuse box for hi beam that I could piggy back from??
The relay I'm using will be a bluetooth one in the engine bay with the switch on the key ring or dash - I had this on my late D3 and it worked well.
I tend to ponder these ideas when I'm away so maybe someone can help please.

Same as a D3/4

Pic up the wire behind the LHS headlight, Blue/Blk rings a bell but it’s a long time ago.

Thats what I had done on my old D3 - I just thought this might be cleaner and easier!
Sometimes I think too much!!!!!
