Hi everyone, new to the forums, but have been an amateur with rc for awhile, and I had a hopefully simple but kind of oddball question.

I am looking into getting a 1/10 emergency flasher lightbar that uses a 3 pin to be hooked up to and controlled by CH3, but does anyone know how to wire one of these accessories up to a standalone battery, possibly with a switch? I understand I need positive and negative on the black and red, but is there a way to still control the accessory, by wiring in a switch?


Thanks for any help, I’m trying to make a police truck for my son and would love to ad flashing lights, and these light bars look perfect, but I would need to have it on a separate battery and don’t know if I could just feed it power and control it a switch and expect it to flash, or if I’ll need to spoof the controller to cycle through the different flashing modes.

I can’t post the listing to what I’m looking at specifically, but I believe that any CH3 accessory would essentially function the same, and just need power and whatever that mystery wire feeds to it.
