The reason I found it, I had got some pre-wired LED's with resistors and I just wanted to check one to find out what it's value was after I had contacted the wires against the tracks while powered up (NCE 5amp). I had to peel the shrink off one to see the colors. It had 5 bands, brown, black, black, violet and yellow. Found by experimentation that the yellow was the 1st band to enter. Came up with 470 ohm. The LED was quite bright (warm white) but not overly so, and holding the resistor between the fingers indicated no heating of it.
