OSRAM DIADEM CHROME traffic lights have a striking, exclusive design: their chrome look is made possible by an advanced, absorbent interference coating. The lamps emit an orange light only when they are operational. At other times they are almost invisible and have no irritating colour effect. DIADEM CHROME lamps are ideally suited to all indicator lights with transparent covers.
OSRAM- worldwide operating German company was founded in 1919, where it is engaged in the production of various lamps and bulbs.
