ONN-M4-50 Wholesale LED Tower Warning Light CE Approved Multi-color for Machinery
Product Overview
The ONN-M4-50 is a compact, 3-tier industrial signal tower light engineered for clear visual status indication on small to mid-sized automated equipment. Featuring a traditional fixed-layer design with Red, Yellow, and Green high-brightness LED segments, this unit delivers reliable machine status communication at an economical price point. Each color draws only 1.4W while maintaining luminous intensity suitable for shop floor environments. Available in three mounting configurations (Foldable, Pole & Plate, L-Bracket) and three voltage options (DC12V, DC24V, AC100-240V), the ONN-M4-50 integrates seamlessly into new installations or retrofit applications.
