WHAT TO DO WHEN LIGHTS FAIL

1. Check that all circuits are on and that all plugs are plugged into a sufficient power source.
   
   
2. Check the plug fuses of the light set. If the filament within the fuse is broken, replace the fuse. It is also sometimes necessary to spread plug prongs of plugs to insure circuit contact. This is a common problem.
   
   
3. While the light set is plugged into a sufficient current, run a finger slowly over the bulb tops. If the light set comes on while touching a particular bulb, this bulb is most likely causing a short in the circuit. Remove and replace this bulb. In this case, the wire was not making contact with the light socket.
   
   
4. Check that the appropriate amount of light sets are plugged into each other, end to end. There should be no more than two (2) sets of lights plugged into each other.
   
   
5. If the lights are plugged into an extension cord, there may be an overload. Make sure there are not too many lights plugged into the cord. Also check the plug fuse of the extension cord.
   
   *NOTE* It is always best to check any light set while it is plugged into a wall plug outlet.
   
   
6. Should a light set be burning brighter than normal, there are most likely more than eight (8) to fifteen (15) bulbs that have burned out. Find and replace those bulbs that are not working. Do not replace burned out bulbs while the light set is plugged in. This will cause a current surge and will burn out the new bulb.
   
   
7. When replacing a burned-out bulb in a minilight set, it is helpful to use a tester. This will dramatically simplify the repair of light sets on both trees and displays.  To use the tester, plug one light set into the plug outlet on the light tester. Push the test button on the tester; a buzzing sound will come from any defective bulbs. Remove and replace the bulb(s).  On light sets of over fifty lights (light spheres, 100 light sets, etc.), remove one bulb from the end of the set or sphere, and plug the light into the tester. Push the test button. Remove and replace the bulb. Continue testing each light until the defective light is found.
