high-voltage signal lamp required. This flashing light emits 5 rapid flashes, stops and then repeats. It's easy to see in a well-lit room. The specs show that it runs on 12100 VDC. I checked its performance at 1024 volts. Consumes about 3 watts. Build quality is decent enough, but don't expect it to survive drops over 6 feet. Detachable lens. Overall good value for money.
