Vertitron Midwest (VMI) makes a red LED dot-matrix position indicator. These indicators are exclusive to Minnesota Elevator (MEI), Vertitron's sister company. Elevators with this indicator are often incorrectly referred to as Schindler or KONE.

Vertitron Midwest (VMI) makes buttons intended to replace Schindler MT and ThyssenKrupp Aurora buttons. These look similar to MAD BS and are relatively rare, and can light up blue, red or white.
