The aftermarket headlights were fully functional when they were installed. Then the high beam bulb went out on the passenger side headlight(it was an H1 bulb). So I bought 2 new H1 bulbs and replaced both high beam bulbs. The driver's side stills works, but the passenger side headlight still does not work. I replaced the relays and the fuses, and the passenger side high beam bulb still does not light. What is the problem here?
