Older British cars all had indicators on the right, and a lot of foreign manufacturers fell in line for a while, for the British market, but there are few if any, making RHD-specific column switch assemblies now. My 2007 Getz has them 'the old way', but an i20 will be the 'modern way'. Columns with left-hand indicators are correct in an LHD car, as they always have been. I'm not really sure when the change started, but it's a good while ago and virtually complete now. I not sure what Japanese manufacturers do, as their home-market cars are RHD.
There are other things which derive from an LHD world - it's why the on/off/volume knob is on the far side of the radio, etc..
