Suppose there’s a recurring burnout problem with your light bulb. In that case, it may indicate that there’s a loose connection. It may also suggest a problem with sending electricity to the bulb. This typically happens if resistance is met along the circuit board or wire.  There could also be a problem with the grounding. Electrical grounding is an alternative pathway provided to the circuit if there’s a fault in the wiring system. Both these issues are easily tested with a multimeter. Alternatively, if you’re unsure about how to proceed, ask your electrician to take a look.
