All LED's (excluding the LED indicator lamps) require a resistor in series to limit the current to the required specification (usually 20mA). Use Ohm's law to calculate the value of the resistor required. Most LED's have a voltage drop of 2 volts. Blue & White LED's are 3.5 - 4 volts.
V=IR (volts = current(amps) x resistance(ohms)). For a 12VDC supply voltage @ 20mA the required resistor would be:
10 (volts) / .02 (amps) = 500 ohms
LED'S ARE SUITABLE FOR DC ONLY
