How to select and use Christmas Tree light

Steps:

• While selecting lights, extension cords or outside decors, check the packaging or read the instructions carefully, and look to see that the manufacturer has labeled the item as approved for use in exterior locations. Do not use any item outdoors unless it is designed for exterior use.
  
  
• Each year when you get your lights ready to hang, take a moment to check the bulbs, sockets, light cords and extension cords for nicks, cuts, broken insulation or exposed wires. Discard damaged lights and cords.
• Most exterior extension cords have three-prong (grounded) male and female plugs. Do not use any cord if the grounding leg has been removed or damaged.
  
  
• Never try to force a three-prong male plug into a two-prong cord or outlet. To properly adapt a three-prong cord to a two-prong outlet, use a UL-approved adapter plug with an attached ground wire. Be sure that the ground wire is connected to a proper ground source, such as a cold water pipe or a grounding rod driven into the ground.
  
  
• While using spotlights for temporary exterior illumination of decorations, use an approved lamp holder to hold the bulb. Most of the types have a gasket for sealing the bulb in the socket, and some types have a metal or plastic spike attached to simplify staking the light securely to the ground.
