Hello. My name is ***** ***** I will be helping you today.

Have you ever had this trailer hooked to this truck before? If so did the lights work properly then?

Have you driven at all with the trailer? If not drive it around a couple of miles and recheck it. A lot of times its a ground issue and driving it a little will knock off any rust in the way on the ball connection.,
