Not at all. I have HID and everything works as it should.
I think what some people may be referring to is the 'warm-up time' of HID.
When an HID bulb is fired up, it doesn't reach full intensity immediately. There's a short 'warm-up time' - maybe around 30 seconds - before the bulb reaches full intensity.
Your pass-to-flash will work, it just won't be as bright since the HID bulb will be 'cold'. (Some people will only install HID on the low beam and run a regular or yellow halogen bulb as the high beam)
