When you're choosing signaling indicators and operator controls for an industrial panel, the first big decision is usually between a low-voltage DC tower with an audible alarm and a set of simple AC-powered panel lights. On one side is the Signal Tower Stack Light 3-Layer Buzzer 12V 24V DC Industrial Andon Steady at $41.95. On the other is the 10Pcs 120V AC 10mm GREEN Panel Mounting LED Indication Signal Pilot Lights at $4.98. Here's how to match them to your machine and your wiring.
Quick Verdict
Pick the tower if operators need to see and hear machine status from a distance and your control circuit is 12V/24V DC. Pick the pilot light set if you're wiring standard 120V AC panel indicators and need simple green status lamps.

Where the Signal Tower Wins
If your application demands a visual signal that can be understood from across the room plus an audible alert, the tower has the capabilities. Its three light layers can each run continuous or flashing, so you can set up distinct status patterns. The built-in 90 dB buzzer removes the need for a separate sounder, and the IP54 rating suits factory dust and moisture.
Where the 10-Pack Wins
When your control panel just needs multiple green indicators to show which circuits are live, the pilot light set is a straightforward route. It runs on 120V AC directly, so no DC converter is required. The compact 10mm size works in tight layouts, and panel mounting keeps installation simple on cabinet doors and control boards.
Product Notes
Signal Tower Stack Light 3-Layer Buzzer 12V 24V DC Industrial Andon Steady
Choose this if your machine operators need both visual and audible feedback at a glance. The tower combines three light layers with a built-in buzzer and a 100,000-hour LED life, all in a unit rated IP54 against dust and moisture. You can set each tier to continuous or flashing, so the same stack can communicate normal running, warning, and stop conditions. It requires a 12V/24V DC supply, which means it won't run directly on a standard 120V AC panel circuit. For applications with DC control power and a need for buzzer alerts, this Andon unit is the more capable pick.
10Pcs 120V AC 10mm GREEN Panel Mounting LED Indication Signal Pilot Lights
Pick this set when your build simply needs green power-on or running status across a panel. Each lamp uses a 10mm green LED and operates on 120V AC, so it can be wired into common AC control circuits. Panel mounting keeps the installation clean on cabinet doors and control surfaces. These lights are designed for visual signaling, so any audible or tiered alarm requirement will need an external sounder or a different device. If you're after a simple, direct AC-powered indicator, this set gives you exactly that.
Final Choice by Use Case
For a production cell with 12V/24V DC controls, flashing tiers, and an operator who needs to hear alerts, the Signal Tower Stack Light is the right fit. For a control panel running on 120V AC that needs multiple green status points with minimal wiring, the green pilot light set is the smart pick.
