Aircraft
During descent from cruise altitude of FL330 and through FL240; we noticed a Master Warning light illuminate without any associated annunciators. We continued the flight trying to figure out what was causing the Master Warning. Reaching 9;500 FT; we noticed a dimly illuminated 'Right Thrust Reverser' Unlock light. Upon noticing the full illumination of the light and test of the indicator lights in the cockpit; I completed the memory items for the associated malfunction and called for the checklist. While completing the checklist; the 'Right Thrust Reverser' Unlock light would not extinguish.Noting that we would be executing a visual approach via a traffic pattern to the runway; I elected to follow the checklist and shut down the engine in an attempt to assure minimal effect should the reverser deploy in a more unfavorable altitude and attitude: i.e. in the traffic pattern on a turn to final within close proximity to the ground. After completion of all checklists; including the single engine approach and landing checklist; a normal approach and landing was made. The flight concluded without event.
Beechjet 400 flight crew received a 'Master Warning' light during descent; and then a 'Right Thrust Reverser' unlock light. Following the checklist; the right engine was shut down as a precaution and the aircraft was landed safely.
