These are two bulbs that show the phenomenon of light bulbs that survive a fire. The thin glass envelope softens as the gas inside expands. Because they are so delicate this happens at the earliest stages of the fire and once the gas is expelled they harden pointing to where the fire started.

In 25 years and many fires I have been able to save only these two. Many firefighters have never seen one. As the one shows they do not even have to be installed or on for this to happen.

This is the best. The glass is almost too thin to handle. It was in a ceiling lampholder, base up and pointed straight at the paper basket, (dust bin) where the fire started.

Everyone knows electrical equipment can start a fire, but not too many know it can solve where and how a fire started.
