## Description

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° Ideal For Machine and process status indication IoT and home automation alerts Workshop and lab equipment monitoring Fun project builds and escape rooms Package Contents 1× Tri-Colour Tower Light with Buzzer (12V DC) Resources Wiring Guide for 12V Lights with Microcontrollers
