^^^^^ This 100% +++

The OEM fog lamps are 55 watt I do believe, or at least 35 watt.

The HID kit for the fogs that I'm using is 35 watt, so no worries there.

The low beams on my car are OEM HID's, but I have no doubt that putting 55 watt ballasts on this system will not create any undue heating stress on the wires/loom/switches etc.

All the halogen light low and high beams are 55 watt OEM, so again, no issue if you are upgradeing or changing out from Halogen to HID.

And the reality is after the first draw of power to ignight the bulb, HID's draw a lower current value than does a halogen bulb. That reduction in amps puts less stress on your alternator over time, so I don't see a downside.

OEM foglamps are 55W halogens. If you're fitting a HID kit, I wouldn't exceed 3000k, in either 35 or 55W guise. If you go too white, they will be useless in fog. The glare will actually blind you.
