How to Fix a Lighted Christmas Garland
Check the Light Set Type First
Check the listing for your light set before you buy a tool. A tool that fixes LED sets will not work on incandescent sets, as stated in the listing here. Note the type, then pick a tool that names that type.
Test the Bulb and the Fuse
Use the bulb and fuse tester on the bulb first, then on the fuse. A bad bulb will show up on the tester, and a bad fuse will too. Test one part at a time, so you know which part to replace.
Match the Spare Bulb
Check the base and wattage in the listing before you buy spare bulbs. A bulb with a B15D base and 0.43 watts fits only a light set that takes that base and wattage. Check the plastic housing too, as stated in the listing here.
Unplug the Light Set First
Keep the light set unplugged while you take out a broken bulb, as stated in the listing here. Take out the broken light with its base and throw it away. Then place the new bulb in the base, with its wires on either side.
Test the Outlet as Well
Check the outlet with a voltage tester if the light set will not turn on. A GFCI tester will show the voltage and the trip time on its LCD readout. Read the display, then check the wiring condition it shows.
