The compliant ones have a connection to the park circuit to turn them off. You could do the same with a double throw relay powered by the park circuit and connect the power to the lights thru the normally closed pole of the relay
richms: I thought they must be off when the parks are on?

see thats what I thought.. So I was trying to remember if the LED's on the new Audi's turn off when their headlights are on... but I cant for the live of me remember it or not. My mate swears they stay on.. So I don't want to install mine unless I am doing it correctly and legally.
You'll need a transistor and relay. Or a grunty transistor might even cut it depending on amperage draw. From a rusty memory: probably a PNP connected to the headlight circuit so when it's triggered it flicks the relay off. Ask a guy with thick glasses at DSE (or even better Jaycar these days) and he'll draw you a circuit diagram in a jiffy.
