is the u.s wiring for headlights different to the uk?

msborg, in the uk the terminology for 'sidelights' is not indicators( I think this is where the confusion has come from in your post?) the lights that come on if you turn the light switch one turn to the right (or clockwise) if you wire them into the harness of the lights that corrrespond to this switch then you will not get the lights coming on if you put the indicators(turn signals on) - this defo works as this is what i've done with mine,
