Yep that's what I surmised from the other threads.
However two issues give me pause about "blind" use of an add-a-circuit type product.
First, if possible I'd rather avoid hacking up the engine compartment fuse box. (note1:

Second, Add-A-Circuit and the various knock-offs are
really bad design. The add-on fuse doesn't slave off of the original. It is instead, its own circuit. This leaves open the possibility of placing more load on that wiring than what the manufacturer intended. That could create a wire-on-wire short,
deep within the tens of feet of
wiring harness somewhere in the vehicle; and it will challenge and frustrate even the most experienced mechanics to diagnose, find and fix related electrical gremlins. (note3:

As alluded to before, I'll need to do some
personal investigation in order to determine the next best step. But what I've done for similar nano projects in the past, is use a relay to power add-ons. The relay coil itself is powered via an appropriately fused circuit. For examples...

One thing to note, is the USDM engine compartment fuse box gets an individual 10A fuse for each light. One is earmarked for Left Fog, Right Fog, Left High Beam, Right High Beam. I'm going to look for the UK owner's manual as it may provide some clues as to how the power is handled with the DRLs. Looks like there's a common fuse for the reverse lights and don't see a fuse at all for the marker and low beams. These curiosities might be satisfied via (crappy Helm CD) service manual.
