This isn't strictly a design classic, but the Cesare Leonardi and Franca Stagi-inspired Gloss Pendant Lights are based on one, specifically the 1969 Bowling table light by the previously-mentioned designers.
That particular design was an early spot of recycling, the two designers using a headlight from a scrapped Fiat 666 lorry for the actual light, adding a coloured back and support for the finishing touch. Indeed, if you want to see the original, see over the page for an image. These updates use the same 'headlight' look for a pendant light, adding a black or white gloss finish, chrome trim, 2m of flex and an included halogen bulb.
Two designs available (as above), with prices from £75, dependent on size.
