This is a pair of decent quality Tourist Trophy reproduction Lucas foglamps, also known as "Pathfinders," at 25% off Moss Motors list.
They have a clear fluted lens to throw a broad, flat beam. These are made in Asia, of good quality, although the detailing is not as good as the more expensive reproduction "MADE IN ENGLAND" 576 lamps we carry. The crest at the top of the lamp is correctly marked "LUCAS" but there are no other markings on these lamps.
They were sold as options on many British cars, and thousands were sold as accessory lamps in the 1950s through 1970s.
Yellow bulbs are available for an additional $30/pair.
