Scenic O/S Headlight staying on

Hi, the o/s headlight on my 2010 Renault Megane Scenic III 1.5dci appears to have a permanent positive feed which results in the headlight being permanently on. (the n/s headlight is not effected and operates normally on the switch). I suspect it may be to do the headlight relay. Has anyone experienced this problem? Also does anyone know the location/colour of the headlight relay?? any help would be great. thanks
