Express post shipping available (product has a short lead time)

A tri-colour tower light with red, yellow, and green LED segments plus a built-in buzzer, powered by 12V DC. Each light and the buzzer are independently controlled via separate wires, making it easy to indicate machine status, project states, or alert conditions from a microcontroller.

The light mount rotates 180° so the tower can be installed vertically, horizontally, or at any angle in between. Mounting holes on the base allow secure attachment to panels and enclosures.

Key Features

  • Three Colour Segments – Red, yellow, and green LEDs
  • Built-In Buzzer – Audible alert controlled via a separate wire
  • Independent Control – Each light and buzzer activated individually by grounding its wire
  • Adjustable Mount – 180° rotation for vertical, horizontal, or angled installation
  • Mounting Holes – Secure panel mounting

Wiring

  • Brown wire – Common +12V power
  • Red wire – Red light (ground to activate)
  • Yellow wire – Yellow light (ground to activate)
  • Green wire – Green light (ground to activate)
  • Orange wire – Buzzer (ground to activate)
Tip: If driving from a 3.3V or 5V microcontroller, use NPN transistors or N-channel MOSFETs to sink the 12V current from each wire. For best brightness, light only one segment at a time — the red and yellow segments may not both reach full brightness simultaneously.

Specifications

  • Operating Voltage – 12V DC
  • Current – ~50 mA per segment
  • Light Source – LED (red, yellow, green)
  • Mount Rotation – 180°
