• Do Trailer Lights have to be Grounded to the Main Trailer Connector Ground
  As long as each of the lights on your trailer are grounded to a clean, bare metal surface then you will be good to go. On aluminum trailers though sometimes a jumper ground does need to be run to the main trailer connector ground. But not with steel frames.

It is likely the turn signals will not function while the vehicle is not running and the key is in the off position. When the vehicle is...

• How to Connect Trailer Wiring to Optronics # ST8RB and # ST9RB Trailer Tailllights
  If you have the Optronics # ST8RB and # ST9RB, no connector is needed. On the back of the taillight, there is a hole for the stop/turn and a hole for the running light wire.

• Are the ST8RB and ST9RB Submersible Lights
  I have a solution for you, but neither the # ST8RB nor # ST9RB are submersible lights. Instead, you'll want to use the # ST6RB and # ST7RB - which are the submersible versions of those lights. These are still incandescent tail lights that look exactly the same, have the same dimensions and are the same 2 wire electrical system, they're just sealed up so that they can be safely used on boat trailers.

• Replacement for Old Trailer Square Tail Light 4-5/8" x 4-5/8"
  I might have an option for you but without more detail, like a photo, it would just be a guess. That said, the size you mentioned is pretty common more or less for square trailer tail lights like the Optronics Combination Trailer Tail Light part # ST8RB for passenger or part # ST9RB for driver. If this is what yours looks like, I recommend using these as the two stud mounting pattern is pretty standard so don't get bogged down in the small dimensional differences.

• Running Lights Function but Brake and Turn Do Not on a 2006 Carlson Utility Trailer
  It could definitely be a ground issue. Since you were able to duplicate the same result with the same trailer on two different vehicles, than it is pretty safe to say the problem is somewhere on the trailer. I would start with the trailer connector and work back. Trace the ground wire, usually white, back from the connector. Make sure it has a good clean connection to the metal of the trailer frame. Paint, rust and corrosion can insulate connections so make sure it is good metal to metal...
