Not sure the switch to 4 headlights is as easy as you think... There are only two ads I see in the rags on 9004's that are not just 45/65's competition limited and another (he might be a dist for gene). Call CL, I believe his price was 20 some bucks a piece.... As far as I know, since these hi output are not street legal, yer not going to find them at your local trak auto....... Scott
