Default st170 xenon headlamp conversion

hi guys,

looking into swapping over my standard mk1.5 lamps with the st170 xenons. now i understand that you need washers ect to pass the MOT but is it 'easy' to do? do i need extra wiring; if so what?

any help is much appreciated
Thanks!

you dont need washers if xenons wernt fitted as standard. my RS passes with them every year.

for the rs i had to change some internal wiring, but unsure if you will need to do the same, i can dig the diagram out if you need it.

all you need is the headlights, bulbs, ballasts, and ignitors.

does the 1.5 have indicators in the headlights? or down on the bumper?

because the FRS's are down on the bumper you might have issues.

i honestly dont know if the wiring will differ, it might be worth getting an auto electrician to have a look, or you could always follow the diagram and hope,

the FRS has the same high and low beam as a 1.5 but with indicators in the bumpers. there was a german website that tolk you how to do the hole thing, including washer jets and auto levels on the suspension, bt i cant find it any more... sorry i couldnt help more

Yea I he thought of that which what I might have to do as a last resort!

I've found that website, ( www.Foka24.de/Focus/Xenon.html )but Google Translator isn't the best
I'm going to buy a pair anyway and ill make some decent instructions and update.

Thanks for your halp mate

Hi Cris Cronin
Did you ever manage to get those lights wired up?
If so could you please let me know which wires needed changing, splicing or bridging.
im struggling to find the correct information.
many thanks in advance.
Steve, nottingham.
