7.4V is waaaay too high for a yellow LED, unless you have a resistor in series, or multiple LEDs. I thought it looked a bit of an odd colour. Single yellow LEDs only go up to about 2.2V. You do run the risk of burning it out if you have got it set up with the full 7.4V over the LED.

Ofcourse there's a resistor in series. That's Page 1 in the Great Western-European Almanac of LED Soldering!

I am probably going to add other LEDs in the actual robot, just for redundancy.
