There are kits available that stop the flicker yet still allow the Day time running
lights to function the way they are supposed to.
Here is a link to a company about an hour south of us:

I'm not sure if they actually list/show the module for fixing the
"Flicker" issue, but they do sell them.
The other thing you can do is wire the fog lights to come on as Day time running
lights, then you won't have the flicker problem.
Keep in mind that the Halogen headlamp reflector does not cast the light beam
properly when switching to a HID capsule as the arc being generated by the bulb
is not in the same position in headlamps reflector compared the to filament of a
Halogen bulb.
I've been looking at HID conversions and I personally find that the quality just is not there.
However, if you buy European specification KJ head lamps, you will get a Superior light output
from them.
Not to mention that you will also get electrically hight adjustable headlamps.
I find those to be a more advantageous and am looking at those as a future
mod.
