Fixing Christmas Lights: Simple Steps for Repair and Maintenance

Tools needed:

  • Bulb tester

Materials needed:

  • Light string fuses
  • Replacement light bulb

Steps to fix Christmas lights:

  1. Check and Replace Fuses:
    • Slide back the plastic covering on the plug to access the Christmas light fuse.
    • Replace any blown fuses. Some strings might have multiple fuses.
  2. Test and Replace Bulbs:
    • Use a bulb tester to check each bulb for issues.
    • For the tester to work, ensure the lights are correctly plugged into the outlet.
    • Identify and replace faulty bulbs. Often, changing a problematic bulb resolves the entire strand’s issue.
  3. Use a Christmas Light Tester Pen:
    • Alternatively, touch each bulb with a tester pen to identify defects quickly.
    • If one defective bulb is identified, there might be more, so check the entire strand.
  4. Safety and Storage:
    • When removing lights, handle them carefully to avoid damage.
    • Plug in the lights before storing to confirm they’re functioning.
    • Store the lights properly in their original containers or similar ones, ensuring the bulbs don’t collide, to maintain their longevity.
    • Remember, traditional bulbs last about 1,000 to 1,500 hours while LED lights have a longer lifespan.

The essential tool needed for fixing Christmas lights is the bulb tester.
