Christmas Lights Survival Guide

The Unexpected Dangers Of Christmas Lights
It seems that every year the bar is raised higher and higher in the neighbourhood Christmas lights competition.

Displays are bigger and brighter, with more and more lights added each successive year. Home owners go to a lot of trouble and some of the displays look quite impressive, but did you know there is a dark side to those festive lights?

There are a number of injuries and even deaths each year directly attributed to Christmas lights.  Electrocution, fire and falling off roofs can make the quest for festive lighting a hazardous endeavour.

The major source of problems are old and poorly maintained light strings.

That old set of Christmas tree lights you’ve been dragging out every December for a couple of decades should probably be replaced.  Any lights that operate with 240 volts at the lamp have the potential to cause electric shock or start a fire.

Old Christmas lights can also cause overloaded circuits, a problem that has been solved by new LED lights.

LEDs are ideal for Christmas lights due to their low power consumption, low voltage power supplies and the range of colours that can be produced.  Even with new LED lights there are safety issues you need to to be aware of.

You should only buy your Christmas lights from a reputable local retailer to ensure they are safe and approved for use in Australia.

If you buy online make sure your lights are sent from an Australian based distributor and not sent direct to you from overseas.  It doesn’t guarantee the safety of the lights but it does give you an opportunity to seek redress in the event of a problem.

If you import any electrical product direct from overseas you assume all the responsibilities of an importer and will be personally liable for any problems the lights cause.

If some one is injured by non-compliant lights you will be responsible.  If you home is damaged by fire due to faulty Christmas lights your insurance company may not pay if the lights that caused the damage were not approved for use in Australia.

The usual commonsense safety measures still apply to low voltage or LED lights.

Don’t use lights that have damaged cords, broken lamps or damaged power supplies.

Don’t mix old and new light strings, they are probably not compatible.

Do keep power packs and extension cord connections out of the weather.

Do use a proper ladder for accessing your roof and make sure it is footed correctly and secured at the top if possible.

Do ensure that any lights you buy are approved for use in Australia.

While a good display of Christmas lights can look amazing, some people go just a little too far.

Last year a Townsville man disconnected the street light outside his home in order to make his lighting display stand out more effectively. He removed the cover from the base of the pole and pulled apart the live wiring connections, which disabled the  street light but created a very dangerous situation.

Enjoy your festive lighting display but make sure you keep your family safe as well.

Frequently asked questions

Can lightning damage my home even without a direct strike?

Yes. Your home can still be damaged even if lightning does not strike the building directly. A nearby strike can send energy through electrical wiring, plumbing, power lines, or the ground, which may damage your switchboard, appliances, and internal electrical systems.

How does lightning enter a house?

Lightning can enter a house through several pathways, including electrical wiring, switchboards, plumbing, phone and data lines, antenna cables, and ground current. This is why homes can be affected by nearby strikes as well as direct ones.

What happens when lightning strikes near your home?

When lightning strikes nearby, it can create dangerous power surges, trip circuits, damage appliances, affect your switchboard, and in some cases start electrical fires. Some damage is immediate, while other faults may remain hidden until later.

Can lightning really damage my computer, TV or appliances even if it doesn’t strike my house directly?

Yes, an indirect lightning strike, for example to nearby power lines, ground, or trees, can send powerful surges through wiring, data lines, or plumbing into your home and damage electronics. If a storm is approaching or thunder is heard, unplug non-essential devices immediately.

Is it safe to shower, wash dishes or use water during a thunderstorm?

No, plumbing and water conduct electricity, so using water during a storm is risky. Avoid showers, baths, sinks, washing machines, or other plumbing-connected appliances whenever there is thunder or lightning.

Are surge protectors enough to protect my home and devices from lightning?

Not necessarily. Surge protectors help with ordinary surges, but they are typically insufficient against the massive energy of a nearby or direct lightning strike. For better protection, consider grounding, whole-home surge arresters, or a full lightning protection system.

If lightning strikes nearby, but not my house, could my home still be at risk?

Yes. Ground current, soil conduction, or nearby strikes can transmit dangerous current through plumbing, wiring, or foundations, even when your home was not directly hit. Treat any thunderstorm seriously, unplug devices and avoid water or conductive contact until the storm passes.

Is it safe to use cordless or mobile phones during a thunderstorm?

Yes, as long as the phone is not plugged in or wired to the home’s electrical or phone system. Avoid using corded landline phones during storms.

How far away can lightning still be dangerous?

Lightning can still be dangerous even when the storm does not seem directly overhead. If you can hear thunder, you are close enough to be at risk and should move to proper shelter immediately.

Can lightning cause a house fire?

Yes. Lightning can overload wiring, damage switchboards, and ignite building materials, especially in homes with older electrical systems or inadequate surge protection.

Do I need lightning protection for my home?

Not every home needs a full lightning rod system, but many homes benefit from proper grounding, whole-home surge protection, and an up-to-date switchboard. A licensed electrician can assess your level of risk and recommend the most suitable protection.
