How Long Does a Road Flare Last?
Traditional burning flares usually last between 15 and 30 minutes. Wind and rain can shorten their lifespan. LED road flares, on the other hand, can last anywhere from a few hours to several days, depending on the battery life and settings.
How Do Traditional Flares Work?
Traditional flares work by burning a mix of chemicals. You light them by striking the cap or pulling a tab, similar to a match. Once ignited, they’ll start to burn red due to the presence of strontium nitrate. Always handle them carefully since they get extremely hot and can cause burns or fires if not used properly.
Do Traditional Flares Have a Shelf Life?
Yes. Most last around 3 to 5 years if they’re kept in a cool, dry place and away from moisture. Over time, the chemicals inside can break down and they might not be able to ignite. Always check the expiration date on the packaging.
How to Use a Flare
-
Make sure you’re in a safe spot away from anything flammable. Hold the flare at arm’s length and point it away from your body.
-
For traditional flares, remove the cap and strike it against the ignition surface. If it has a pull-tab, pull it firmly.
-
Once it’s lit, place it on the ground away from traffic or anything that could catch fire.
-
If using multiple flares for an emergency, space them out in a line to make yourself more visible. When the flare burns out, let it cool completely before disposing of it.

Traditional flares typically last between 15 to 30 minutes. LED flares can last from 6 hours to over 24 hours. Flares can be extremely beneficial if you’re in an emergency situation. It can save your life.
