HID in high is always not recommended, Halogen is best. HID bulbs need to warm up for a while before they reach their full potential. If you install HID in fog lights, it will ruin the beam pattern and destroy the purpose of fog lights, if you just want a change, its better to get a yellow spray for plastic and glass lenses and spray it over your fogs or get jdm yellow halogen bulbs for the fogs.
