Unit powers on and all functions work but there is no flash strobe when tested. I think it is the bulb as it looks burnt on one end (see last pic) but not 100% sure as I don't have another bulb to test. I was able to test the middle bulb and that works fine. Also when I hit the strobe test I do hear a click so I know the button is working just no flash. Selling for parts becasue I am not sure about the strobe bulb. Also the soft rubber body is a little sticky.
