I would contact him directly for pricing, I don't want to say anything wrong on the that subject.
Only issue we are tracking down now is the lack of highs when you click em on, the silly OE system clicks off the lows when you click on highs, so the ballast loses power (powered from low signal) So, right now we are gonna grab the pass/flash high beam signal and splice it to the full on high beam signal at the BCM. Sucks since this makes things not exactly plug and play but we shall see.
As of now, I have lows and halogen highs, but when you click on the high the ballast depowers and HIDs don't like the cycling. So I can flash highs and have halogen/HID but can't keep em on.
