How to Choose the Right Flare for Roadside Emergencies: LED vs. Traditional

When you find yourself in a roadside emergency, selecting the right flare can be a critical decision. This guide aims to clarify the key differences between these types of flares, helping you make an informed choice that prioritizes your safety.

Understanding the Purpose of Emergency Flares

Road flares serve several essential functions during emergencies:

• Signaling Distress: Whether you’re stranded on a remote road or involved in an accident, road flares are effective tools for signaling for help, visible from considerable distances.
  
• Marking Accident Scenes: They help delineate the accident area, ensuring that other vehicles maintain a safe distance (typically 100-300 feet away).
  
• Guiding Traffic: In situations involving roadblocks or hazards, flares can direct traffic, reducing the risk of further accidents by creating a visible path.
  
• Illuminating Work Areas: For emergency responders, flares can light up the immediate area, enhancing visibility during nighttime operations.
  

Types of Emergency Road Flares

Emergency road flares come in various forms, each with its own strengths and weaknesses:

Traditional Incendiary Road Flares

Traditional incendiary flares are the classic type most people associate with roadside emergencies. They ignite a combustible material, typically containing strontium nitrate, which burns brightly for a limited duration—usually 15-30 minutes. These flares are highly visible and can penetrate even the thickest fog.

How They Work: Traditional flares consist of a cylindrical tube filled with a pyrotechnic composition, including:

• Strontium Nitrate: Provides the characteristic red color.
  
• Potassium Perchlorate: Acts as an oxidizer to support combustion.
  
• Sulfur and Sawdust: Serve as fuels.
  
• Binding Agents: Hold the mixture together.
  

To activate, simply remove a protective cap and strike the flare’s tip against a designated surface, similar to lighting a match. This ignites the chemical mixture, producing a bright flame.

Advantages:

• Extremely high visibility (up to 3000 candela)
  
• Effective in all weather conditions, including heavy rain and snow
  
• Can be seen from up to a mile away
  

Disadvantages:

• Short burning time (typically 15-30 minutes)
  
• Potential fire hazard, especially in dry conditions
  
• Environmental impact due to chemicals like potassium perchlorate
  
• Cannot be extinguished once lit

LED Road Flares 

LED (Light Emitting Diode) flares represent a modern approach to roadside emergency signaling. These electronic devices utilize advanced circuitry and high-intensity LEDs to produce bright, attention-grabbing light without combustible materials.

How They Work: LED flares consist of:

• High-Intensity LEDs: Arranged in a circular pattern for 360-degree visibility.
  
• Microprocessor: Controls various light modes and patterns.
  
• Battery Compartment: Houses replaceable batteries (typically AAA or CR123A).
  
• Durable Casing: Often made of high-impact polycarbonate for added durability.
  
• Waterproof Sealing: Usually rated IP67 for water and dust resistance.
  

When activated, the microprocessor directs power from the batteries to the LEDs, creating various flashing patterns designed to attract attention effectively.

Advantages:

• Long-lasting operation (up to 100 hours on a single set of batteries)
  
• Multiple light modes (steady, rotating, SOS) and colors (red, blue, amber)
  
• Safe to handle with no risk of burns or fires
  
• Reusable, making them more cost-effective over time
  
• Environmentally friendly, as they don’t release harmful chemicals
  
• Durable, often crush-proof and waterproof
  
• Versatile, with magnetic bases or hooks for easy attachment
  

Disadvantages:

• Higher initial cost than traditional flares ($30-$50 for a set of 3-6)
• Requires batteries (usually AAA or CR123A)
• Slightly less visible than traditional flares in extreme weather conditions
• May not perform as effectively in thick fog or heavy snow

Chemical Light Sticks 

Chemical light sticks, often included in emergency kits, generate light through a chemiluminescent reaction. They are self-contained, waterproof, and can last from 8 to 12 hours.

How They Work: Chemical light sticks contain two separate chemicals in a plastic tube:

• An Oxalate Ester (usually diphenyl oxalate)
  
• A Fluorescent Dye
  
• A Glass Vial: Inside the tube containing hydrogen peroxide.
  

Bending the stick breaks the glass vial, allowing the hydrogen peroxide to mix with the other chemicals and triggering a reaction that emits light, with the color depending on the specific dye used.

Advantages:

• Easy to use (just bend and shake)
  
• Waterproof and non-flammable
  
• Longer glow duration (8-12 hours)
  
• Safe for use in potentially flammable environments
  

Disadvantages:

• Less bright compared to other flares (typically 5-10 candela)
  
• Single-use only
  
• Limited color options (usually green or red)

How to Ignite a Road Flare

Igniting a road flare is a straightforward process, but it’s essential to follow safety precautions to ensure your safety and the effectiveness of the flare. Here’s a step-by-step guide on how to ignite a traditional incendiary flare:

1. Choose a Safe Location: Before igniting the flare, ensure you are in a safe area away from flammable materials and vegetation. Ideally, you should be at least 100 feet away from your vehicle and other hazards.
2. Remove the Protective Cap: Most traditional flares come with a protective cap that keeps the igniter safe from accidental activation. Carefully twist or pull off this cap to expose the igniting tip.
   
3. Strike the Flare: Hold the flare away from your body and point it downwards, away from any flammable materials. Strike the tip against the designated striking surface (often found on the protective cap or packaging) in a swift motion, similar to lighting a match. Ensure you apply enough pressure to ignite the flare.
   
4. Position the Flare: Once lit, place the flare securely on the ground or attach it to a stable object. Do not attempt to hold a lit flare, as this poses a significant fire hazard.
   
5. Monitor the Flare: Stay at a safe distance while the flare burns. Be aware of wind direction to avoid smoke inhalation, and do not leave the flare unattended.

How Long Road Flares Last

The duration of a road flare’s burn time varies significantly between traditional incendiary flares and LED flares:

• Traditional Incendiary Flares: These flares typically burn for 15 to 30 minutes, providing a bright and intense light that is highly visible. While they offer excellent short-term signaling, their limited burn time means they may not be suitable for extended emergencies.
  
• LED Flares: In contrast, LED flares can last anywhere from 20 to 100 hours on a single set of batteries, depending on the model and the light mode used. This extended duration makes LED flares an ideal choice for prolonged emergencies or situations where visibility is required for an extended period.
  

While traditional flares provide immediate visibility, LED flares excel in longevity, allowing for extended use during emergencies.

How to Dispose of a Road Flare

Proper disposal of road flares is crucial to minimize environmental impact and ensure safety. Here are guidelines for disposing of both traditional incendiary flares and LED flares:
