Back in the mid 1980s, my parents knew a volunteer fireman and he had a beacon on his truck that was fairly large, but it only had three sealed beams. It stuck in my memory as all of the ones that I saw before and after were always one, two or four. He let me climb on the bed of the truck to take a closer look and it definitely had three bulbs, evenly spaced and they rotated like any other normal two or four beam rotating beacon.
Was his light some creation/modification or did someone actually make a beacon with three sealed beams?
