Red, yellow and amber LEDs usually require 2-2.4V. Green requires 2.4-2.8. Blue and white require 3.4-3.8V. These are typical values for 3mm and 5mm through-hole varieties; surface mount and high power versions will differ.

thanks for the fast answer

It depends on the LED. The most common through-hole LED's are 3.3V and 5V. Be sure to put a resistor in series with a LED to prevent it from blowing due to overcurrent.
