To determine if an LED Christmas light is blown, start by visually inspecting the light strand for any evident signs of damage or burnt marks. Next, test the light with a Christmas light tester, which can help you pinpoint the exact bulb or bulbs that are not working. Alternatively, checking each bulb with a multimeter set to the continuity function can confirm if the individual LED is receiving electrical current. A lack of continuity indicates a blown light. Always ensure the lights are unplugged before attempting any checks or replacements for safety.
