Review on CZC AUTO Submersible Trailer Exclusive by John Stowers

Installed these lights last week. Tinned marine wire was used for the connections for the lights along with a new 7 wire junction box and some of these watertight outer boxes. WARNING to buyers: The side marker lights have been marked yellow for the run of tan wire and gray for ground. The polarity is reversed. CHECK CABLES BEFORE INSTALLATION. I used the screw connectors in the boxes and checked that my wiring was correct with a current probe (the glorified test gauge), but the yellow and gray side markers were reversed. Hope this helps someone in the future. As many have said before me, the set of cables they send is rubbish. Get better wires. I may have spent an additional $75 on tinned marine wire, junction boxes, and jacketed 4-pin wesbar wire. worth your money. The lights themselves are fantastic. Very bright!
