good evening everyone
I'm having trouble making my light test run
the Key works Normal on the PMDG Airplane but when I trigger it the Anunciators do not light up
can anybody help me !
thank you

In order to help you must supply more info about syste,

Do you use the default script with OC4BAv4?
Do you have the Opencockpits or own built MIP?

Have you checked in SIOC/IOCPConsole that the there is any action when you turn on the Light Test switch?
