These test lights plug into the spring terminals on the Firing Module and allow the operator to see shots in real-time for performance rehearsal and testing. Super-bright LEDs are visible in daylight or at long distances at night. One LED assembly fits two channels of the FM-24. They come in packs of 12, enough to outfit an entire FM-24 for rehearsals or channel testing.
Please note that Continuity Test Mode will only run with e-matches. The LEDs Test Lights do not pass continuity, as the LED acts as a diode (instead of a short-circuit like an e-match) and will not allow enough current through it to show continuity is viable.
