Review on 🚘 Enhance Your Toyota Tundra, Tacoma, or 4Runner with our LED Blue Backlit Push Button Switch Kit for Rear Lights by Mark Cole

Works quite well. It fits perfectly in the empty space in the 2019 4Runner. If you hook everything up the way you want it, chances are you'll have a button that stays on all the time, even when the machine is off. It took some trial and error with the wiring, but you can't turn it on unless you press a button. There really isn't any indication of that, which is why I deducted a star.
