Review on Partsam Submersible Utility Trailer Identification by Erick Bowers

Put them on my boat trailer and they work great. Ideal brightness of driving lights and brake lights. There were some signaling issues initially, but they were fixed after the main trailer was reworked. Make sure both lights are well grounded and preferably with short ground wires (I used 4" ground wires). All connections sealed with 3M heat shrink tubing/marine epoxy. Never had a problem with the shorts tumbling them down the boat ramp .
