What to do When Your Emergency Exit Lights Burn Out?

Every building, whether a commercial mall or a factory outlet, must have appropriate safety systems installed, especially against fires. Many options can help contain the flames and prevent further damage, from fire extinguishers to fire suppressants. This is the part where property safety gets covered. But what about the civilians present inside the complex? To escort them out safely, most building owners install emergency exit lights.

These are nothing but rectangular boxes on which EXIT word is carved using LED tubes. It usually glows with a green or red hue to create a visual contrast. Based on how huge the building is and the number of entrances it has, there can be more than one exit light. Owners need to ensure these lights are monitored and maintained throughout.

What is the most common problem with emergency exit lights?

The most common problem with emergency exit lightsis that they can burn out anytime without any indication. If that happens, no indication will be there for others about the safety entrance or exit door. As a result, there will be chaos inside, and the chances of fatal accidents or injuries are way more than one can comprehend.

That’s why knowing about the exit light burnout signs is imperative. This not only helps prevent such a worse scenario but also ensures everyone gets escorted outside safely. But the question is, what causes the exit light to burn out?

First of all, most exit lights have small LEDs connected in series with one another. Inside one LED bulb, a tungsten filament is responsible for converting electricity into light energy. If, somehow, the tungsten gets oxidized or breaks, the LED won’t be able to glow, and the entire circuit will go black. This is what we call a burning out of the emergency exit light.

How to identify emergency exit light burnout signs?

There are certain ways to identify whether the emergency exit lights have burnt out. The following are some of the most accurate ones.

  1. The main bulb is not glowing: Every exit sign needs one or more main bulbs that will glow continuously 24×7 without any break. If it is not glowing, it means the exit light has burnt out, and you need professional help.
  2. Low voltage: If the bulb attached to the exit light constantly flickered, the gas pressure inside decreased. As a result, the voltage output is not as expected, so you must replace the bulb as soon as possible.
  3. Reserve battery: In rare cases, the fault is associated with the battery providing power to the emergency exit light. It either needs a brief repair or an entire replacement to provide continuous power to the light.

When the emergency exit light needs an entire replacement?

You must replace the entire set if the bulb is damaged in the emergency exit lights. That’s because the output won’t be satisfactory even when you repair it. So, instead of spending more money on repairing it, you can get it replaced.


With this above discussion, you now understand what exactly is meant by the statement that emergency exit lights have burnt out. Based on this, it’s your call whether you want the damage to get repaired or replaced or want to take action effective immediately.
