Honestly I wouldnt get HIDs for high beams. They take a while to warm up.
I got EuroEFX HID's and I can't find them anywhere online I think they only sell to dealers. I won them for free at a local shop that was opening(shady, I know). But never the less they are bright as Sheol. I NEVER use my high beams now because even with my headlights aligned at the right height they don't do too much for me.
SW burbs? Would those be the SW burbs of Chi town?
Welcome to NICO.
edit: Before I won my free kit I was going to get the 35W kit from DDM with the slim balast. I think I few people here are using them and from what I read they love 'em.

second edit: The highbeams on Altimas are different bulbs than the headlights. I'm pretty sure that means that we wouldnt use a bi-xenon kit in our cars based off of the 10 second googling I did to see what bi-xenon was but I'm not sure.
