I am looking into getting new bulbs for my catz foglights, along with matching ones for my Headlamps for my 98 GSR(lowbeams only). I started looking around today and found that I was totally lost as to what lights I need. They have h3's and h4's and 9005's and 9006's and others like that. Could someone tell me what I will need for the lowbeams on a GSR headlight. Also what usually goes into fogs? I would really appreciate some help.
