Brake/tail light needed

I live in AZ and to make my 1988 fourtrax street legal. Which is really for being legal on maintained dirt roads I’m not actually riding on paved roads but I’ve been told forest service gives out lots of tickets if not street legal

I need a brake light and license plate light oh and a horn. Non of which are on this older quad

Anyone find a good option for an aftermarket brake and tailing

Currently has just a tailight
Front brakes hydraulic and read cable

Thanks
