F it is a screw in bulb the likely reason for bulb failure is the ground spring contact that rubs on the thread as you screw it in
they loose tension and when the machine is in use they vibrate on the side of that screw section and arc just like a welder
this continuous arcing creates excessive current flow and that tends to burn the bulbs
the fix is to turn the power off at the wall and use something to bend that spring tab out further so that there is resistance as you screw the bulb in
