Re: Cat 777D Mining Truck
A switch is basically just a potentiometer with two (or three or in some cases even more)) settings.
So it really depends what positions the switch tells the receiver to move the servos to. I remember reading that these positions are not adjustable with the Traxxas, but it would be worth doublechecking that.
What type of lighting kit are you looking for? I would assume it should work with a channel that goes "full lock".
If all fails, you can actuate a mini switch with the servo to turn on/off the light.
For the dump bed, you can install a buzzer and/or warning light to start once the bed leaves its resting position. Again, use a small switch, this time actuated by the dump bed itself.
