ok, For my car, The normal low beam should have a D2R HIDs on it but due to compliance, they change it to a H1 normal halogen bulb. As for the high beam, it's the original H4. If you on the high beam, both the high/low on the H4 will light up. If you have the lower light with the fog light option, Good. For me, nothing turns on when I switch on the fog lights. These PIAA bulbs are original PIAA from Japan. I manage to get them cheap, therefore I can offer them to you cheap too. it's easy more than AUD100 selling outside.
