dwayner no, i havent but ive always thought the interior light was too dull, or the cover too dark - and i would have prefered a light in the glovebox
Or you could just buy the cover & try to source you own led bulb http://item.mobileweb.ebay.co.uk/viewitem?itemId=261118690679&index=10&nav=SEARCH&nid=22694133327
Would it not be possible to fit the light from another car. They usually just clip into a hole in the head lining so maybe a slight alteration to the Copens lining. Or put a higher rated wattage bulb into the existing fitting.
