I asked the same task of Brit a while back. IIRC it came in somewhere in the neighborhood of $700 PER lamp assembly. So $1400 for just the headlights. If you search through the site here you'll find it in one of the threads.cvsir7turbo wrote:sveintore,
Is it possible to get new xenon headlamp assemblies from your local nissan dealer?
I'd be willing to drop the coin if the performance was up to snuff. While I have no doubt it is better than our Halogens, I just don't think it is going to prove to be $1500 better. For that I could purchase an ARB/Shrock front bumper and mount driving lights on it and still have left over gas money.
