Looking for this #RCCar lighting controller. It takes three input channels from the receiver, has 19 JST output connectors to connect LEDs to. PCB looks like this and is usually in a black plastic case.
I only found shops that sell it with a specific LED set for one particular car, like so. https://www.aliexpress.com/item/INJORA-TRX4-RC-Car-Front-Rear-LED-Lights-Lamp-Group-for-1-10-RC-Crawler-Traxxas/32856375659.html
I want just the controller alone or with a generic LED harness.
