How Do I wire spot lamps on my Hyundai Santa Fe?

[fcatt]

Does anyone know how to wire spot lamps so that they come on with the high beam and go off with low beam. I know they would work if I simply connected to my high beam feed wire but I also know that this is not the right way to do it as I should fit a fuse and relay.
Ref my previous question regarding spotlamps. I forgot to mention I am in the UK. The configuration is legal here.
