Description / 2x5x7mm Rectangle Wide Angle Cool / Clear White LED

The 2x5x7mm Rectangular Cool White LED is the standard replacement indicator for vintage audio receivers, ham radio equipment, and industrial control panels. The flat rectangular face sits flush behind panel cutouts and aligns perfectly with printed labels — a round LED in a rectangular indicator window looks wrong. This is the correct form factor.

Cool White is a modern cool white option for equipment where a clean, bright indicator is preferred over period-accurate warm colors.

Primary applications

  • Vintage audio/stereo restoration: Drop-in replacement for burnt-out indicators in Marantz (2270, 2245, 2230, 2275, 2325), Pioneer (SX-1250, SX-950, SX-750, SX-650), Sansui (G-9000, G-8000, AU-717), Kenwood (KR-9600, KR-7600), Yamaha (CR-1020, CR-820), Technics, Harman Kardon, and Realistic receivers. The 2x5x7mm rectangle is THE LED size for silver-face era hi-fi restoration. AudioKarma and HiFi Engine forums specify this exact form factor.
  • Ham radio equipment: Indicator replacement for Kenwood TS-830S/TS-530S, Yaesu FT-101/FT-757, Icom IC-751/IC-745, Drake TR-7/R-7, and Collins transceivers. Mode indicators, VFO selection, and S-meter elements. QRZ.com and eHam.net communities source these LEDs regularly.
  • Vintage computing: Power and drive activity LEDs on Apple II/IIe, Commodore 64/1541, IBM PC 5150/5160, and DEC VT terminals. Also modem status indicators (Hayes Smartmodem era).
  • Test equipment: Front panel indicators on HP/Agilent signal generators, Tektronix oscilloscopes (2465, 2467), Fluke bench multimeters (8050A, 8060A), and Keithley instruments.
  • Guitar amps and rack gear: Channel indicators on Marshall JCM800/JCM900, Mesa/Boogie Rectifier series, Peavey 5150/6505, and Fender. Also rack effects (Lexicon, TC Electronic, Eventide).
  • Industrial control panels: Status indicators in PLC panels, relay logic boards, CNC machine controls, elevator panels, and HVAC annunciator boards. The flat face sits flush with panel labels.

Restorer’s note: When replacing LEDs in vintage audio equipment, check the original circuit’s current-limiting resistor value. Most receivers from the 1970s–80s were designed for 10–20mA indicator LEDs with resistors already on the board. If the original LED was incandescent, you may need to add or change the resistor.

*Use 15V instead of 12V for vehicle/alternator sources to account for charging voltage (13.8–14.4V).

Frequently Asked Questions

The 2x5x7mm rectangular form factor was the industry standard for Japanese hi-fi equipment from the mid-1970s through the late 1980s. It fits Marantz 22xx series, Pioneer SX series, Sansui G series, Kenwood KR series, and most receivers from that era. Check that your original LED position uses 0.1 inch (2.54mm) lead spacing.
For period-accurate restoration, match the original color (usually red or green). However, many restorers upgrade to blue or warm white for a modern look while keeping the original rectangular form factor. The choice is aesthetic — any color works electrically.

DC power recommended: LEDs are designed for DC. Running on AC will cause flickering and reduce lifespan. If you're using a low-voltage AC source — such as a model railroad transformer output or DCC track voltage — convert it to DC first with a bridge rectifier.
