dodgy lights

hello all,when I turn my d600 off instead of both headlights switching off only one does,i thought it might have been linked to the indicator switch but even with them turned off the headlight still remains on,if relevant it is the left hand headlight as I sit on it, for the time being I have pulled the power wire of the bulb,any help would be appreciated,thanks

 

yes I did then turned it back to the lock position,the headlamp remained on,so I will be playing hunt the relay tomorrow,thank you both

 

hello all,thanks for the reply`s,went looking for relays,gave up and bought a manual found them swopped them over hooray the dipped beam worked properly,talking to one of the lads,he said take the relay apart clean both surfaces gently put it back together and it should work and it did,so being the tight git that I am I don't have to buy another relay just yet

 

Thanks for that
