Well, I am not sure about that, but all I know is i was that close buying a set of sir headlight from the dude that lives at orlando, but he told me that if i have hid kit then not worth it or unless willing to go for oem factory bulbs in order to have sir headlight. I was like fuck that and asked why. He said sir headlight is very lightweight and it will make hid bulbs go bad very fast due flicking. He replaced hid bulbs 6 times when he had sir headlight on his civic which is why he fed up and want to sell it, so I decide to not go for sir headlight because Im kinda a highway person so hid kit is very dependful.
