so i want to blackhouse my headlights and fogs (cause i dont like chrome at all) and apparently all the blackhousing places are on the east coast, and if possible i want to do it local or buy and send out a separate set. anyway, i wanted to buy a separate set somewhere and was wondering how to tell the difference between the hid and non-hid versions. i was told that they look almost alike but have different wiring setups. so... how am i supposed to know the difference?

ps... i posted here and not in the lighting section because this is specific only to the 2IS.
