Theres a company called ESP Design (they advertise in Revs) - I got a Clio catalogue from them and in it they sell.....
"Renault fog lamp kit - genuine renault item - contains two foglamps, their plastic housings, wiring and a new control stalk for your steering column"
£99.95 per pair (incl VAT), ESP Part No. REN.77014 they include a photo and it is for the Clio Mk2.
Had a quick look at their website espdesign.co.uk but couldnt see the foglamps. Their telephone numbers 0870 751 8000
Hope that helps!
Phil.
