The auto headlights should work as before it has nothing to do with the headlight itself, I have fitted projector headlights used ones, Remember that new valeo ones, don't come it the auto levelling motor (£38) and it is different from the standard light motor, as well as that there are plastic parts that rivet onto the front of the headlight to support the bumper or secure the headlight you might be able to fit them without it as they are hidden behind the bumper, Lastly you will need bulbs I used the osram nightbreaker ones for full beam and dip I had Xeon headlights on my 172 Clio as standard and thought they where the best the night breaker bulbs are as good without stupid HID and higher powered bulbs. With the projector headlight the bulbs are hard to fit when mounted, So put new bulbs in before fitting and make sure they are seated properly as it can make a big difference to the beam distance. I would buy the valeo ones as some of the others you see about have wires that need spliced in and others have different bulb fitting door layouts and plugs I have not seen them all but with the valeo ones you know the connector is going to fit in. Remember the used ones will come normally with everything fitted but you will have the problem of condition. Remember look for ones from other Mk3 models not just Clio 197 or 200's they are the same and you are more likely to get a better price also remember the different shapes of head light for the facelift bumper they will have a notch for the bumper to sit into the headlight at the outside edge on newer models. I think that mine cost me £40 for one as it came off a std Clio and the scrapyard charged that price for Clio mk3 headlights I took it out myself, the other cost £80 ebay. I think there should be a fact/info section in the form with the pros and cons of things like this projector headlight subject with all the FAQ's answered, what's involved what to look for and avoid buying junk copies that will never be a good job. The cornering lights have a separate plug which your loom does not have the extra plug but the headlight works like a normal headlight.
