Choosing signaling indicators operator controls comes down to how the signal reaches the person who needs to see it. One option is a panel indicator set that fits into a control-panel setup; the other is a stacked tower signal that can sit near a workstation. Both help communicate machine status, but they suit different wiring and visibility needs.
Quick verdict
Pick the AB Allen Bradley 800T-PC416 for a no-fuss panel indicator. Pick the 5-Stack USB LED Andon Tower Signal Light for a station light with more signaling options. The Allen Bradley is the simpler panel component; the Andon is the more complete station signal.

Product notes
AB Allen Bradley 800T-PC416 Indicator Lights 4 Function Red Blue Green Clear
The AB Allen Bradley 800T-PC416 is a 120V panel indicator set with four lamp colors and four function positions. It is a good fit when you need to show things like manual/auto mode, warnings, or machine conditions. One reason to choose it is that it includes three rubber spacers, a tightening mounting nut, and a decorative barrel nut, so the hardware you need for a panel installation is there. The trade-off is that it is sold as an open-box item, as-is and without its original box. That is the main condition to keep in mind before putting it into service.
5-Stack USB LED Andon Tower Signal Light indicator Buzzer 5VDC Industrial Warn
The 5-Stack USB LED Andon Tower Signal Light brings five LED colors into one tower, along with a built-in 85dB buzzer and a 9-foot USB cable for 5VDC power. It is intended for workstations, assembly-line call systems, and CNC machine status alerts, and its adjustable bracket makes it easy to direct the signal toward operators. The main reason to choose it is the combination of visual and audible feedback in a single plug-and-play package. It does cost more than the Allen Bradley option, though, and it needs a 5V USB source; it also carries a California Prop 65 warning.
Final choice by use case
For signaling indicators operator controls, use case decides. Go with the AB Allen Bradley 800T-PC416 when you need a direct panel-integrated signal for mode or warning indication. Go with the 5-Stack USB LED Andon Tower Signal Light when you want a self-contained station beacon that gets noticed in a busy work area.
