This is an O.E.M. Left headlamp assembly for a 2003-2004 Land Rover Discovery II. This is the style for a 2003-2004 Discovery. This headlamp is the European version as indicated by the one amber corner light and the one clear light, as stocked on the left hand drive 2003-2004 Discovery. The other difference between the North American and the European version is that the N.A. version have illuminated reflective corner strips, while the Euro version have the reflectors but they do not light up. We also offer the North American version in our store. If you're retrofitting to an older Discovery or Range Rover, it should not make a difference. It's all preference, though.
