What’s up guys I just got my jdm integra from japan and am having issues with the driver side headlight. It flickered on then off and now won’t turn on. I read online that the ballast may have went out so I swapped the ballast with the passenger side and still wouldn’t turn on. I swapped the good passenger side ballast onto the driver side bulb and it worked so I’m sure the ballast went bad. I gutted the oem driver side ballast and installed a aftermarket ballast and it worked. I went to on a drive the next day and it worked for a bit then turned off and wouldn’t turn on. I supplied power and ground to the connector and still would not turn on I supplied power the fog lights and daytime running lights and they worked. I also found this black box wired into the harness behind the driver headlight that’s says ipf usd style. I read this box is for daytime running lights. Could this have burned the harness? Any other suggestions on what to check before I replace the ballast again? I don’t want to put another one in for it to burn. I have attached pics of the box
