My design for the 737 Master Caution Annunciator. It is fully operational with push button and can be edited for your needs. I 3d printed this. One adjusment I would make next time is to add a further 2 LEDs in the opposite corners. You will need 2 LED's (Red) and one 12mm tactile switch with round push button.

This design is worked around the decal supplied by You can create your own from this file.
