Not sure if this has been posted before (couldn't find anything) but after getting fed up with the lack of courtesy light in the Trophy after shutting the door i simply swapped it over for an updated version:
If you want to do it better, turn the light around so the map reading light is on the passenger side like it should be. I modified mine to sit the correct way as even FF Clios have it the wrong way round, one of many things they didn't bother changing in the conversion to RHD.
