What did you want them for? Fog lights are 95% there so others can see you in the fog, and maybe 5% to help you see a little better in fog at 5 mph or less. For that, I'm sure those worked fine. But I'd bet they'd be almost useless at illuminating much in front of you.
Those cross-country HID lamps are a whole different kettle of fish. Expensive fish, at that.
