A replica set of engraved panels which are for use in the glareshield of the Boeing cockpit. The fire warn unit has built in red LED and master caution has inbuilt yellow LED. These fit onto the backboard (shown in photo) which has two push buttons connected.
The six pack unit also is prewired with yellow LEDS which can be designed to illuminate when an issue occurs like in reality.
These are pre-owned and therefore there is clear signs of use, but would be an ideal low cost project to finish off your glarewing for either the captains or first officers side.
