Hi, wanted to buy HID headlights for the evo 8 online and wanted to know, since am living in a Right Hand Drive country, if the Left Hand Drive Headlights are in any way different/compatible from the RHD ones.

 

They are different, and odds are you will get pulled over fairly quickly. Lhd aim slightly right and rhd slightly left to prevent blinding oncoming traffic while maintaining useable aiming height.
I know of two people that had to get their "totally JDM bro" headlights in their cars and both got tickets within a week for improper lighting (lhd here).

 

The largest difference is the cutoff shield on the projectors

LHD: _______/-----------

RHD: -----------\_______

 

^^^ that's actually a great demonstration of it.
