Holiday Decorating FAQs, answered by experts

Cold weather can cause older incandescent Christmas lights to fail by causing cracks in the finish or the glass itself. Modern LED lights are affected in the opposite way and perform even better as the temperature drops. 

If you take home a pre-lit Christmas tree but want to spruce it up with blinking lights, don’t worry, there’s a simple solution. You can easily replace the light bulbs on the pre-lit tree with flashing bulbs. For a more subtle look, only replace some of the bulbs with flashing bulbs.

Yes, you can synchronize Christmas lights with music to create a DIY light show. To do this, you will need several components. For hardware, you'll need standard holiday lights, decorations, lawn ornaments, tools, outdoor-rated extension cords, a computer, and a light show control system or digital controller. You will also need specialized software to program the show; popular options include Light-O-Rama (LOR), Vixen, xLights, and Animated Lights. Some, like Vixen and Animated Lights, are considered more beginner-friendly. The process involves using the software to program your lights, choosing an audio method such as speakers or an FM broadcast, and testing the entire system to make sure it's working correctly before the show.

Yes, you must use an extension cord specifically rated for outdoor use to power outdoor lights, such as Christmas lights. Extension cords intended for indoor use lack the protective properties to withstand exposure to outdoor elements. To safely hang and power lights outside your house or in your yard, always connect them to an outdoor power source using an outdoor-rated extension cord.

Several options for hanging Christmas lights won't damage gutters. Using shingle clips avoids any hardware contact with them, and using plastic gutter clips minimizes the likelihood of scratching gutters. Remember not to rest a ladder, especially a metal one, against the gutters, and use a ladder stand-off device or stabilizer if you need to use an extension ladder.
