Another legal question

There's also this, which I just put into service as my auxilary light
switch - centre off, one side illuminated red and forces them to
switch on always, and the other side illuminated green and is switched
to select on-with-high-beam:

(you need an ABN to buy off them)

Careful, the switch LEDs are powered from the the terminals they're
switching, which doesn't always suit the circuit you're trying to work
with. A circuit involving a couple of relays and a few diodes (as
well as the back EMF diodes across the relays) seem to be the minimum
configuration I can come up with keep the switch itself illuminated
properly - with one relay though, it conveys enough information at
least to show me I currently have my lights on.
