• Recommended Replacement Trailer Lights With Side Lights For Small Utility Trailer
  We have just what you are looking for. I recommend the LED Submersible Trailer Stop, Turn and Tail Light, part # STL8RB. This is for the right side of the trailer and is a stud mounted LED light. It has the side marker light that illuminates when the running lights are powered. For the left side of the trailer you will want part # STL9RB. I have attached a product review video and have also attached a drawing that shows the dimension for these lights you can take a look at.

• 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...

• Preferred Method of Grounding Trailer Lighting Circuits
  Running a direct ground up to the trailer tongue or junction box would certainly work, but the only time I'd see that as being necessary is if the lamps were connected to a non metallic structure or a metallic structure that wasn't directly connected to the trailer frame. If the lamps aren't connected to a metal structure in direct contact with the trailer frame, you can use a short length of # DW02359-1 wire with a # DW05702-1 ring terminal on each end to serve as a jumper wire that joins...

• Do LED Trailer Tail Lights Have A Ground Wire Or Do They Ground Through Mounting Hardware?
  There are two different styles of LED trailer tail lights. Some are like the Optronics LED Combination Trailer Tail Lights # TLL160RK and have a ground wire on each light which needs to be grounded to the frame, and the other two wires connected to the tail light and brake light/turn signal wires on your trailer. There are other styles of tail lights that do not have a ground wire and instead get the ground through the mounting hardware. Both styles install by wiring the tail light and...

• How to Change Light Bulb in Optronics ST8RB Trailer Taillight
  Changing the bulb is simple. Remove the screw on each corner of the front of the lens and gently pry the lens away from the housing. Be careful not to damage the gasket between the lens and the housing as doing so will allow water into the interior of the lamp. With the lens removed, you can push in on the bulb and twist it clockwise then pull the bulb free. Install the replacement # A1157B bulb in reverse order..

• 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. Each of these holes will have a smaller hole directly below it. Strip back the insulation on the wire by about a 1/4 inch, twist the copper strands of each wire tightly and push it into the hole in the back of the lamp as you're pushing a small screwdriver into the smaller hole. Once the wire is fully inserted, remove...

• Utility Trailer Light Wiring Diagram and Required Parts
  I have attached two basic trailer light wiring diagrams of utility trailers for you to check out. The difference between the two diagrams is the type of wiring harness that is being used. Diagram 1 shows a traditional wiring layout with jumper wires to provide running light functions for both sides of the trailer and Diagram 2 shows a wishbone harness. The wishbone harness has two running light wires, one for each side of the trailer. Diagram 2 is the preferred method and it is more common...

• Replacement Tail Light for 2000 TrailStar Bass Tracker Pro Boat Trailer
  I looked up some photos of a 2000 TrailStar Bass Tracker Pro Boat Trailer and it most likely uses either the Optronics Combination Trailer Tail Light part # ST16RB for passenger and part # ST17RB for driver side or the Optronics Combination Trailer Tail Light part # ST8RB for passenger side or part # ST7RB for driver. Unfortunately, you'd have to replace the entire tail light as we'd not have just the lens.

• Replacement Tail Light Assemblies for 1976 Argosy Camper
  The issue that you're going to run into here is that the lip that you removed is designed to allow you to mount lights on the back because of the curved ends. Because it's such a smooth curve there, you're not going to be able to use something like the Bargman Wraparound Clearance/Side Marker Light - 86 Series - Red - Black Base # 30-86-202. With that said, I'll mention two options for you that you could likely make work by moving the electrical wiring in a bit. First, you could use the...

• 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. In regards to a replacement...

  The quick connect feature on the Optronics Light, part # ST8RB, and part # ST9RB, means that you can connect the wires by inserting them into the four holes on the back of the light. It is not referring to a separate part. The wires would be stripped about 1/4 inch and pushed into the correct hole on the back of the trailer light. The holes are marked with the tail light function that the hole provides. The wire when pushed in the hole will automatically lock in place and give you a quick...

  Yes, trailer brake lights are supposed to light up brighter when the tow vehicle applies the brakes. They are designed to work just like a vehicle's taillights that have the brake lights and the running lights on the same circuit. If you check out the review video link I attached you can see how a very standard trailer taillight # ST8RB lights up with the running lights and the stop/turn signal.
