HID fog lights/headlights

is it advisable to get HID foglights if i already have HID headlights? or will it look bad? any input appreciated, thanks

do u have "Real" hid headlights? and are the foglights "real" hid
real hid use like 30 watts, other bulbs just use like 100 watts to power them to make them LOOK hid, if they are real, go for it, cool to match things and not be a ricer with 5 differant bulb colors. less ur going for the jdm look with yellowish green fogs, which i think are cooler, like lexus cool

no, both the headlights and the fog/driving lights would be halogen bulbs. sorry for the confusion. so basically, i should try and match the 2 bulb colors? (if the headlights are at 5000k, then should i get a 5000k driving/fog light?)
