Finally able to complete this. I have videos showing the modules to control the lights from the receiver.
This RC truck was left unassembled for a few months now as I was having a hard time getting the right LEDs for the side lamps. I ended up buying another set just to strip off the orange LEDs for my use.
Note that the LED set is pre-wired with diodes to control voltage coming out of the receiver. I busted a lot of LEDs thinking I could directly connect them to the receiver =D.
As always, truck is controlled by my White Flysky FS-i6x.
