check for BLOWN fuses test bulb operation, try checking the relay that supplies the headlights power ,that little switch cannot supply the CURRENT that is needed HENCE THE RELAY
fuses OK, Bulbs OK Relay ? Good one will click when u turn on/or off the circuit with your fingers holding the casing u will feel it as the contacts energise . (SAFE TO HOLD AS ONLY 12V) no click replace rely
