Wow its been a while posting on here for me.
As to the foglights, I installed 3K HID bulbs into my EM1 foglights almost the same way as LXDriver. The bulb itself is a little bit longer. But as oppose to removing the factory reflector, I pushed mine forward so the buld would fit. This saved me the touble of widening the buld entry hole and risking getting shavings in the housings. Keep in mind, the output of the light originally and still is straight out in front of the car on the ground, just like the white light fog pics above. Afterwards, I sealed the outiside of housing/butt of the bulb with Silicone sealant (sp?).
I've had them for a few years so so far so good. As much as I have looked at the EM2 fog housings, they look IDENTICLE to and EM1/EK except for the actual shape of the housings.
To conclude, CIVIC209, I think your on the right track and just need to dissasemble the bumper/housing and see what you are working with. Make sure the bulbs are straight and the sealed from weather when you are finished and I think you will be golden.
Battery draw, dont worry about it. If you have a high watt amplifier in your car for a sub if you have one, see if your accessory lights dim when you actuate the hids and such. You might want to go as far as buying a capacitor to regulate voltage for your car. But at least, check the before and after voltage of you 12v dc car battery with a volt meter when you turn your current headlight HID's on. It should be QUITE minimal.
