I can tell you that nobody sells the H4H bulbs locally. You will only find them online. I even tried to find them, but only people that sell HID kits from Japan will have that bulb...and there are not a lot made there. HID Lights USA and I are the only HID importers in GA and mine is from Tawain and their kits are from Korea.

I have H3 HID bulbs for $25 or H3 Plasma Halogen Bulbs for $15. Both in Golden Yellow.
