Wiring driving light

[superroo]

I just need some help wiring up my driving lights. Now they are driving lights so they can only legally be on with high beams as i am trying to do.

The way i have tried to wire them is by tapping into the high beam relay wire(Green/red) and wiring this to a switch. The way this works, is that the on/off switch for the lights does not receive power until the high beams are on. This wire then runs to pin 86 on the relay so that the lights turn on.

The problem is that the green/red wire doesn't deliver voltage as it should or as I expect. With the high beam relay out, the voltage(potential difference) on a multimeter reads 0v with the high beam switched off, and .4v with the high beam switched on.
But put the high beam relay in, and the multimeter reads 12v with high beams switched off, and .4v with high beams switched on.

Is it I’m just using the wrong wire, or am I wiring it wrong all together.

Also i read in another post to use the green/orange high beam wire to trigger the relay. i Don't wont to do this as that wire is only in the engine compartment and it is a high voltage/high amp wire.

Any help would be appreciated.

Cheers
