Cibié is a French automobile lighting manufacturer founded in 1919. It is pronounced like you are saying C-B-A. There are many Cibié models that are period correct for 1960s and 70s BMWs. In 1969 Cibié was merged with Paris-Rhône, then in 1978 merged with Ferodo and Marchal. These 4 previously competing French auto parts companies formed Valeo in 1980.
