When you are looking for an EZGO Key Switch with Factory Lights from Buggies Unlimited, you might want to call us first. We want to ensure that the on and off toggle is actually faulty and not something else. We have a team of techs who will tell you that the one you are dealing with is one of the most robust on the caddie. They do fail, but the chance that something else in the accessory system has failed is much higher. We can get you moving in the right direction after a simple chat on the phone.This is a key switch with hookups for lights. Usually, your caddie will have a two-spade toggle that is just power in and out for the activation circuit. If you have a gas-powered, this will only be twelve volts. If your caddie is electric, it will be the entire voltage of the battery pack. You have those same two and an additional two for the golf cart accessory circuit on a four-terminal switch. Get the wiring correct! So you do not send thirty-six or forty-eight volts to the lights. If you do, they will be really bright... for a minute or two.Buggies Unlimited has your back when it comes to part installation. We cannot do it for you, but we have a team of techs that will be happy to help you over the phone. We have grabbed enough golf cart glory in our golf cart days; now, we like to help others look like the champ.
