I currently have dual projector headlights installed which are using the stock 9005/9006 socket bulbs. I wanted to get a set of Osram Silverstars (the Euro Silverstars since they work better than the US ones). I know they only come in H3 for low beams. What would I need to use these or is it even possible?

Thanks in advance

I would think you need to get a wiring harness out of a set of fog lights that use the h3s. Or you could get the upgrade harness for the hotter bulbs somewhere. Then just take the light apart and pull the harness out, cut the old connectors off, and solder on the new ones. For info how to open the headlights, use the search.
