Your question is based upon the assumption that any one who replies is familiar with the equipment you have (Where ever you are) and how it works.
I am sorry to say but I have no idea what equipment you have or where you are, so I can only guess.
It flashed when it had an incandescent load (Your 40w golf ball lamp)
It does not flash with a low wattage LED lamp
Put a 40w golf ball lamp back and see what happens.
If it flashes it means that all is well and that the lamp is fed via a bi-metalic strip flasher unit, which needs a load to work properly. (Similar to what cars used to have to make the indicator lights flash)
