Bought a 05 x5 that had been in a mild front end accident. Passenger side headlight housing was banged up a bit. Bought a used housing off of ebay, put all new bulbs in both housings. On initial try everything except the passenger headlight works. So I start swapping around ballasts, ALC and igniter from "crashed" housing to "ebay" housing. Made no difference. I then swapped the igniter from the good drivers side to the ebay housing and the headlight turned right on. So I jump online and order another igniter off amazon,

It appears to be an OEM Hella although at around $50 it's around half the price anyone else has one for. I put it into the drivers side housing and it didn't work. Think I got a bad igniter or is there anything else to check? Only other thing I can think is to swap the amazon igniter into the passenger side and see if it works there.
