During a repositioning flight in the descent phase; about 20 nautical miles from our destination; and passing through 10;000 feet; both the pilot flying and I noticed the Master Warning Light flashing without any associated annunciator light illuminated. A few minutes later; we noticed both Right Thrust Reverser Arm and Unlock lights gradually illuminate. The pilot flying ran the memory items and called for the related checklists; which were completed while approaching the airport terminal airspace. The decision was made to shutdown the right engine as a preventive measure in case the right thrust reverser did fully deploy. The single engine visual approach and landing was successful and uneventful. Due to the mechanical nature of the problem; I don't have any recommendations.
A BE-400 Master Caution light illuminated along with the Right Thrust Reverser Arm and Unlock lights so the checklist was completed and the engine was shutdown during descent to preclude full deployment.
