Identify the unlit section in the string. Remove and replace each bulb one at a time with a working bulb from an operational string. Start from one end of the unlit section and move along until the string lights up, indicating the bad bulb. A key tip is to use a voltage tester pen if available; it can make the process quicker by pinpointing the problematic bulb more accurately.
