I have a new (4 day old) Mavic Pro. When it arrived, all of the LED's worked properly. Now, after about 3 hours flying time, the front red LED's do not illuminate. I have checked and double checked the LED ON setting and it is on. I have switched it off and on, and the lights still do not illuminate. It's hard for a beginner to judge direction of travel without the lights to show which is ahead.  Thanks for the help...

Jeff, it seems to be a hardware issue since you are sure the settings are correct.
Have you contacted our technical support to report the case?
