The following ideas are tips for the proper and safe use of holiday lights this season.

* Use lights that are Underwriters' Laboratoryapproved. Check them annually for frayed or exposed wiring, broken bulbs or sockets, or loose connections. Fasten light strings securely to the tree and don't let the bulbs touch branches or needles.

* Don't use indoor lights outside. Hang outdoor lights with insulated staples and Christmas light hooks -- not nails or tacks. Hangingbulbs downward will keep moisture out of sockets.
