Check the listing for details. 12 volt 5mm Blue LEDs with resistor for GM Instrument Panel Gauge Upgrade 20ct. Condition: New. Listed at 23.81 USD. 5mm 12 volt LED cubes for GM Gauge Clusters and Speedo's. Our LED cubes emit 360 degrees which results in excellent coverage with no dim spots. The resistor is internal which eliminates tedious soldering and no flicker. LEDs are polarity sensitive, the short bent lead is negative. If an LED does not light upon installation, simply turn it 180 degrees. The LED will not blow unless excessive voltage is applied. 5mm LEDs are not compatible with the climate control, steering wheel controls and most other dash switches as the enclosure sizes are too small and they will inhibit the function of the switches and controls.
