As for having them here in the U.S., the question is IF you need them:
You can't turn on your fogs by themselves unless you've modded the relay/harness, so IF you have your fogs on, your headlights will be on, and your taillights will be on anyways. Is a dinky little light in the rear going to make a difference while the tails are on for USDM STi/WRXs? I doubt it.
So if it's not used for function, then it's for aesthetics, hence the "CDI factor". In the U.S. for someone without modded fogs at least.
Cosworth CS400's also had them.
