Hi all, im new here, and looking for some advise, i have a focus zetec 09' plate and have got a set of ford focus Xenon headlamps from a ST/RS,

i've put them on the car, the main beam and side lights work fine but the Xenon dipped light does'nt.

any ideas how to fix it? i think it might be a fuse or the plug or something

thanks for any advise
