Little help for my car?

[BP-Revo]

Hmm, I think I'm better off asking this here than on the car forum I'm on, given with you two (squee and Brian) I have an electronics expert and a car guy in the same spot.

Anyway, I have HID headlights on my car, and a standard dual filament halogen bulb that takes care of fog lights/high beams (I'm talking about my G35, FYI). I want to get an HID kit to replace the fog/high beam light, and I was planning to run a "wiring harness" (I'm pretty sure it's a relay). Do you know if the bulbs will have flickering issues?

Sorry for the the threadjack squee...

I think Brian is right about the switch. They probably did that so you can choose whether the LED has power when the switch is on or if it is off.
