ok this may sound confusing but i took the cover of the fog/indicator light off, i then put a sheet of grey plastic over the top of the orange light and also a bit of clear plastic over the top of that and made sure it was a bit bigger than the orange light so that when i put the cover back over it, the cover would secure it, and it turned out the way it did
another member on this forum did a much better job of this, his method was to smash out the orange lens, and then replace it with a bit of acrylic, looks much better and more neat i didnt do this because i didnt want to smash out the orange lens
hope this helps although the way i explained it is confusing lol
