What feature is associated with a glue pot?

The feature associated with a glue pot is the red light. This indicator is crucial for the operation of the glue pot, as it signifies that the heating element is active and the adhesive is being heated to the appropriate temperature for use.

The red light serves as a visual cue for technicians, ensuring that the operator knows when the glue pot is on and functioning properly. This is important for maintaining optimal adhesive properties, as over- or under-heating can affect the glue's performance.

In this context, the other colors do not typically correspond to standard features in glue pots. Therefore, the red light is the most recognized and essential indicator in this application.
