• 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.

• 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...

• How to Wire Optronics Right-Hand Trailer Stop, Turn and Tail Light, Part # ST8RB
  The Optronics Right-Hand Trailer Stop, Turn and Tail Light, Part # ST8RB, connects with two wires. On the rear of the housing are holes to accept bare wire and underneath each one is a smaller hole that serves as a wire release; just insert a small pin (or something like a paper clip) to release the wires. The left-hand matching light is part # ST9RB. If you refer to the included photo illustrating a trailer-side 7-way connector you will be able to see which two wires from the connector...

• 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...

• How To Connect Optronics Trailer Lights # ST8RB and # ST9RB To a Trailer
  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...

• 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 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 Optronics Trailer Light, # ST9RB, Is Not Working On Trailer Lights With Separate Ground Wire
  The Optronics Trailer Light, # ST9RB is a stud mount light that is grounded through the mounting studs. The lights on your trailer are using a separate ground wire. You will have to run a ground wire to the stud to be able to ground the light. I have the Optronics Trailer Light, # STL9RB. This is a same size light with the same features, but has LED lights instead of the incandescent lights. It is not grounded through the studs so it has the three wires ( brown, yellow, and white) like...

• Replacement Tail Light for 1998 Jayco Travel Trailer
  Trailer manufacturers do not often maintain original parts information (or availability) for items such as lights, but we can certainly help you find a suitable replacement. You may want to just install a whole new light kit like # TL29BK or a high-efficiency LED kit # TLL9RK. This will avoid the same problem of no replacement part if the other light on your trailer should be damaged. Both kits include lights, a license plate bracket and all hardware. If you prefer to replace just the...

• Difference Between Optronics Left Hand # ST8RB and Right Hand # ST9RB Trailer Lights
  It sounds like you are referring to the Optronics Right Hand Trailer Light # ST8RB and the Left Hand # ST9RB. The only difference between the two assemblies is that the Left Hand/Driver's Side unit features an additional license plate light to illuminate the trailer's license plate. I have attached a couple short video demonstrations on these lights that you can also check out.

• Wiring Trailer Stop, Turn, Tail and License Plate Light, # ST9RB to a Trailer
  When wiring Trailer Stop, Turn, Tail and License Plate Light, # ST9RB, how you wire it depends on the type of wiring harness you have on the trailer. If you are using a 4-Way flat that includes one tail light wire, you will need to attach a jumper wire to go from one light to the other for running lights like you have described. There is also what is called a wishbone harness, like # A35W42B. This type of harness has the tail light signal split at the plug. There are then two separate...

• 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 Tail Light Lens For Optronics Combination Trailer Tail Light # ST9RB
  The Peterson Lens # 440-15R will work as a replacement for the Combination Trailer Tail Light # ST9RB. The holes for the lens are slightly different so the bolts will sit differently on the Peterson lens as it is not bored to flush mount the lens screws for your Optronics lens.

• Is the Optronics Tail Light # ST8RB Compatible with 3 Wires for Trailer Light Functions
  The Optronics tail light part # ST8RB that you referenced actually doesn't come with any wiring at all. The back of the assembly has holes in it for quick connecting of your light functions. Simply insert the stripped wire into the appropriate slot. This is the passenger side light assembly. For the driver's side assembly you will need part # ST9RB. Attached are some reviews videos and an installation video for you to reference.

• Can Redline Light Guard be Used with Optronics ST8RB and ST9RB Tail Light Assemblies
  The Redline Light Guard # LG440NP referenced in your question is designed to fit the Peterson Square Trailer Tail Light # 432400 and # 432200, however it can also fit other tail light assemblies. The Optronics Tail Lights # ST8RB and # ST9RB that you also mentioned feature very similar dimensions to the above Peterson assemblies and will absolutely work with the Redline Light Guard. The guard itself has an inside dimension of 5-1/2 inches wide, 5 inches high and 3 inches deep. This will...

• Recommended Replacement LED Lights For Trailer That Keeps Blowing Fuses
  The wires with the circuit you are using are not big enough to handle the draw you have so increasing the fuse is not recommended. I recommend replacing the lights you have with LEDs. The replacement for the # ST9RB lights you have now would be part # STL9RB. These draw about 1/10 of the amperage draw the # ST9RB does. This would decrease the draw on your system and a larger fuse would not be needed. Occasionally when LED lights are installed you will have what is called hyperflash,...
