My 2011 plus 4 has Wipac headlamps.
Looking at the headlamp from the from, the tape would be placed on the left hand side of the lens.
The tape should cover the area above the sloping baseline, on the bottom left hand side of the lens.
Both lenses should be taped in the same manner.
FYI, I checked the halfords instructs pamphlet for this info.
