JMo,
Before going there, I decided first to call and understand where they are located exactly; meanwhile, asked him again "sir, do you have the two types?" the guy answered me "people can use this as fog lamp, or driving lamps; I don't know, if you come here, you see it yourself"
Sounds like you are right; they only have one lamp.
Anyhow, now I really wonder; I will go and find it out myself.
