You're probably looking for something like this or similar in terms of a switch for some LEDs. https://a.co/d/032S8cCK Some light kits come with them so you may already have them....if not they're pretty cheap. I along with them one setup on my Kraton and Felony each and a bunch extra as they came with most LED light kits. Technically my xrt has it too as it comes part of the official high power light kit but that's "proprietary". There are ways to retro fit/MacGyver it to work on non traxxas ESCs. Nice thing is, you can control almost every function through the traxxas link ap, such as high/low beams, reverse lights, blinkers, off, and etc. But in general the one linked plugs into your receiver and you can program it to use whoever free button you choose (usually Ch3). Safe bashing!
