I use a standard Empi dune buggy clamp on style switch. It is easy to wire in. As for lights it depends on the unit. On my Rhino I had to add two small lights to the front for signals and was able to flash the rear brake lights. On my wifes Ranger I had to add lights on both ends because of a screwy ground system Polaris uses. There was a way around it but it was way to complicated to be worth it. All total with lights,switch,flasher,wire and misc I normally have about $60 into the turn signals to do a nice job. In Michigan we have to also have: High beam indicator,lighted plate holder,laminated (Auto glass style) windshield,wipers,washers,and DOT tires. Our group has done about 5 of these and if you have any questions I would be glad to help if I can. Just pm me
