Both! lol.
Just been having another play with it now (just to make things more complicated)..... ok, ignition on, sidelights are ok. turn them onto dipped beam - the sidelights are on but only about half power so very dim and when you turn it from sidelights to dipped beam, you can hear a rely clicking.
Have had the connector off the back of the switch and when I run a direct live to sidelights - they work, to the main beam - they work, then to another position (which I suspect must be the dipped beam) a relay clicks but no dipped beam!
There is no power to the connectors on the back of the lights whatsoever....
I hate wiring!
