welcome to the forum Karl
you may want to try posting in the "want to buy" section instead of for sale though
i take it you have checked ebay? time machine bikes normally has a good stock of rsv spares for reasonable prices
but if its bugging you that badly you may have to buy a new set which is going to be.. expensive
you may want to look at the headlight covers you can get, there are a variety of colours & also clear ones designed to save the headlights from stone chips etc, bit late for them now i suppose but when you get it sorted..
best of luck finding some
