First thing first you need to remove the headlight switch, this is done by having the switch in the '0' position, pushing it in and turning it clockwise to the sidelights position, the switch should then hold pushed in this position. As seen in these following 2 pics

Now you can attempt to pull the switch out from the dash, I found this hard so removed the side panel on the dash and gave it a little push from the back, came out easy then.. The panel is easily removed by prising it off.
