I had mine imported from Japan about 2 years ago.....but since then companies have been producing knock-off jdm headlamps for a LOT cheaper. Find them on ebay. They range in price from $150-$250 in price.
The real JDM headlamps have the clear corner marker and the knock-offs have the orange corner marker.
Just beware as the knock-offs have been known to leak and fog up from moisture getting inside the actual assembly....
