    I just noticed something weird tonight. I got my drone back from Dji a couple days ago with them fixing a main control board problem. The front led's are one red one green, and there solid like before but I believe there suppose to be both red right when it's all ready to fly? I haven't flown it for a few weeks so I couldn't remember if they were suppose to be both red or both green, but after looking on some pics on-line looks like they are suppose to be both red. Everything is calibrated and its says safe to fly and all settings are good. It still flys the same and it seems all good as before just the different color lights. I'm gonna have to call Dji Monday to make sure all is ok. I really don't care if there different color, actually I think it looks kinda neat I just want to make sure that it doesn't mean somethings wrong or anything...

    They may have installed the wrong LED diodes...
    Should be two red up front, two green in the rear...when it's warmed up, satellites connected, safe/ready to fly.
    But they all blink red when RTH kicks in, or the flight battery reaches the critical level.

    Red Green. Hahaha what a silly guy that was.
    Well if you don't mind multi coloured headlamps, no problem.
    As long as it doesn't affect any LED error warnings.

    They put a back in your front.

    The LEDs shouldn't have been touched though. And the rear lights change from green, yellow, red, not solid green so not sure how it could be a rear light they have on the front maybe they just wanted mine to be super cool

    They probably soldered the wires from the LED board to the main board the wrong way round. I think it looks cool. :)

    Looking at your photo, this is exactly what you would see if a full size aircraft was approaching. Red is port nav light and green is starboard. So I think this is how it should have been in the first place, I have always disliked two reds at the front. You seem to have got a free upgrade!

    They are 5050 RGB leds, there is no wrong way to wire them. They have a positive, negative and a signal wire. The led driver on the mainboard tells the what color to show. Something else is wrong.
    I believe the front and rear led assembly has the same part number?
    These are not like the old escs with the leds built in.

    You are wrong. They are RGB leds allright, but the three wires that come from the LED board are 2 anodes (for red and green) and one common cathode. The anode for blue is not connected to anything. Obviously when you cross the two anodes you get the result that OP has.

    Update...I peaked inside the vents with a light and could see the yellow and black wires were switched on the led's compared to the others. So I went a head and switched them back myself. All is good now and red in the front on both lights

    What color is the common wire? I'll be adding a switch for the two rear lights in an upcoming project.
