Decided to finally swap out my trailer lights for some L.E.D.’s – 2 tail lights & 2 markers. Had a guy in one of the stores tell me you can’t just swap them out and expect them to work 
— that you need a relay? or flasher? or something tied into the wiring and put in a box somewhere on the trailer in order for it to work. Did he give me good advice. If so, could somebody please explain exactly what the additional part is? Thanks!
