Driving lights have a nick name when not protected: Stone magnets!
These driving light covers will simply clip over the lamps and are totally clear (no mould marks).
As every transparent plastic which is exposed to stonechips, these covers will also become slightly clouded after 12 to 18 months. You could replace the covers by new ones or clean them by using polishing
cream.
It is not quite clear when Lotus changed from the oval S2 style driving lights to the new round S3 style driving lights. Please check on the car before ordering!
