As jon already mentioned I think you mean HID look, they are not HID(High Intensity Discharge) unless you have a ballast, ignitor, and capsule(the HID version of a bulb). It kills me when folks call the blue coated bulbs HID, because they aren't, also all HID bulbs are 30-35w with a bust of 80-150w during ignition.

Now to your question. Your standard bulb is more than likely 55w, which using ohms law current = heat(watts) / voltage, so at 12v(55w is spec'd at 12v) your bulbs would be pulling 4.58amps using an 80w bulb would pull 6.67amps, which is a 150% the stock current. The stock wiring may not be able to handle that. You could risk burning your harness. You could add relays in and tap directly off of your battery to feed the bulbs or buy an aftermarket wiring harness to be safe.
