SHO-ME 03.W3031 RANDOM HEADLIGHT FLASHER The 03.W3031 flasher is designed to flash headlights on vehicles with ground switching headlight systems. "Positive Ground" (or "ground switching") means that the headlight "common" wire is connected to +12 volts, and the headlight is activated when the dimmer switch connects ground (0 volts) to the high OR low beam. This flasher will provide a ground (0 volts) to the headlights when flashing or when high beam override is active.
History: This Hickok 752 has been my trusty backup tube tester for the last two years. It works fantastic, and it rarely get used. But in the time I have had it I have ran 5AR4/6V6/6L6/6SN7/12AU7/12AX7/45/50s all thru it just to name a few.
