IF....YOU USE A (CAR DOLLY) FOR A (TRIKE TRAILER) THIS IS WHAT YOU NEED TO DO. IF YOU DON'T HAVE LIGHTS ON IT YOU NEED TO PUT A LIGHT KIT ON IT. THEN IT NEEDS TO BE RETITLED FROM (DOLLY) TO (TRAILER/DOLLY) AND THEN YOUR GOOD TO GO. HEY IT'S ALL ABOUT $$$$ MONEY $$$$ FOR A TAG. WE GOT AWAY WITH IT FOR A LONG TIME BUT NOW IT'S THE LAW. PAW
