What does the yellow LED mean? 

LED means light emitting diode. Yellow LED means the light emitting diode that can emits yellow color. 10mm Yellow LED is a large DIP LED, lens diameter is 10mm and high is 12mm, big size will make these 10mm through-hole yellow LED have a lager emitting spot.Except the yellow color, BestLED can also make this 10mm DIP LED to be other colors, like 10mm Red Through-hole LED, 10mm Blue Through-hole LED, Amber LED, even 10mm LED diffused multiple colors (which is 8mm RGB LED or 10mm RGB LED)Through-hole LED can be custom, color, lens, wavelength can all be  assembled as your requirement.10mm through-hole LED can also be: IR LED, Yellow LED, Amber LED, 10mm Blue Through-hole LED, 10mm Green Through-hole LED ect.
