Using the proper bulb rating is crucial, as using a higher wattage than recommended can overheat sockets and surrounding components. Before leaving the light on regularly, check for red flags like flickering, buzzing, burning smells, damaged wiring, or heavy grease buildup that could pose safety risks.
