Whether your lights are brand new or safely stored away from previous seasons, a thorough inspection before you begin is key. Start with a trial run before you hang anything – plugging in each strand and decoration, checking that that any burned out bulbs are replaced, and giving them a thorough look-over to ensure all wires and cords are in good repair.
If you notice any frayed or exposed wiring, this is a sure sign it’s time to replace the strand. If you purchase any new holiday lights, make sure they are properly graded for where you will be using them – Outdoor lights for outdoor use and indoor lights for inside. This same rule applies to extension cords and power bars – all should be labeled accordingly on the package or product themselves. And if ever you are unsure, ask.
