I have two Flash Technology FH 306-2 obstruction beacons i am looking to sell. These are the white day strobes with the motorized actuator filter that switches to red for night mode. Both flash heads are used and one unit was working when removed, the other i cannot test. Both are in good condition and the outer lenses have no holes or major chips/cracks. Both will come with a flash tube and i have one user manual. Not sure what these are worth, but entertaining offers, maybe $150 each?
