Have new HID kit but it only contains a single bulb. Is it not supposed to have two? My old HID kit does? <-- Changing to a brighter white.
I was under the impression that the HID functioned as the low beam, even though it's much much brighter then high beam. Hence you still have high and low. But with single bulb I am assuming you only have one --I have seen them with both (single and double) you got to read the description before you buy. but the single may give you what you want.
