Marl’s 528 Series used to replace older Neon Indicators:

Hot water dispensers on aircraft used older Neon indicators. Today, these Neon’s have been replaced with Marl’s 528 Series LED indicators giving a more reliability and a more modern appearance.  The dispenser manufacturer used the same input voltage (110Vac) and the same mounting hole.  This allowed the manufacturer to upgrade the indicators with minimal change to the unit front panel and input voltage.  The more modern appearance and increased reliability resulted in the manufacturer’s sales increasing.
