Review on HOTSYSTEM DC12V 20A Round Rocker Toggle Switch ON-Off SPST LED Illuminated 3Pin Triangle Plug Car Motorcycle Boat Marine Truck Trailer Auto Green 5-Pack by Edy Yukface

I used these for all my light bars etc on my jeep. Very easy to install and look pretty cool when lit up at night. I used a step drill for the holes and they fit perfectly. I believe they require a 3/4 hole. Nice clean finish to them. Inexpensive and I've had zero issues. Though they are not advertised for outdoor use, I used one on the outside of my camper for a spotlight. So far so good.
