Opal design Amber or red when ON Extra lifetimeThanks to state-of-the-art interference

coatingOnly amber or red when operating Up to double the service life compared

with standard lamps

The design light with opal lookOSRAM DIADEM signal lights only emit amber or red lightduring operation – making them the perfect, attractive lightsupplement for halogen and xenon headlamps. Thanks to thestate-of-the-art interference coating, the lamp shines in anopal look and is ideal for all indicator lights with clear covers.In addition, it convinces with up to double the service lifecompared to standard lamps.
