Are these 2volt LEDs or 12volt? Thanks

Good morning, They are simple LEDs, one red and one green in the same package, wired in inverse parallel and they must have a resistor wired in series to limit the current flow, otherwise they will be destroyed. (You seem to be confusing them with LEDs which have circuitry built in to limit the current). The formula for calculating the current flow is V/R=I, eg. V in volts divided by the Resistance in kilohms (K) = I, the current in milliamps (mA). Eg. With a 12V supply, 12V / 1K = 12mA 12V / 500R = 24mA The LEDs have an If max (maximum forward current) of 25mA, so you would normally aim for about 20mA: An 680R (680 ohms) resistor at 12V = 12 / 0.68 = 17.6mA A 560R (560 ohms) resistor at 12V = 12 / 0.56 = 21.4mA Kind regards Sophie

Thanks. I used to be able to get bicolour 12 volt leds that didn’t need a resistor, but they have disappeared it seems. Ah well. Thanks for the response
