4.8mm Straw Hat LED Diode, Bi-Color, Bi-Polar, 2 Leads – High-Performance Wide-Angle Indicator LED

The 4.8mm straw hat LED diode, bi-color, bi-polar, 2 leads is a compact yet powerful indicator LED widely used in consumer electronics, instruments, gaming equipment, signal indicators, and low-power visual displays. Known for its wide viewing angle, balanced luminous output, and bi-polar dual-color design, this LED is ideal for designers, engineers, and purchasers seeking a reliable and cost-efficient visual indicator.

Its straw hat lens delivers a unique flat, wide-beam light pattern compared with standard round LEDs, making it an excellent choice for applications requiring broad illumination coverage and clear status visibility even at long distances or wide side angles.
The bi-color bi-polar configuration also simplifies PCBA layouts—allowing the LED to emit one color when powered in one polarity and another color when the polarity is reversed.
