• 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...

• 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...

• 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...

• Is the Optronics Tail Light # ST8RB Compatible with 3 Wires for Trailer Light Functions

• 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...

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...

• 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...

• 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...

• 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...

• Installation Method for Optronics 6-Function Trailer Stop, Turn and Tail Light # ST8RB
  
• The Optronics 6-Function Trailer Stop, Turn and Tail Light # ST8RB that you referenced does not require a bracket for installation.

These mounting studs also serve a second purpose; they provide the ground connection to complete the electrical circuit. Please refer to the linked video. Certainly if you wanted to mount these with a bracket you could use a simple L-bracket...

• 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,...

• What Does Shock Proof Socket Mean for Trailer Lights?
  
• As you mentioned, some of the trailer lights like the Optronics Trailer Stop, Turn, Tail and License Plate Light, 7-Function, Left Hand # ST9RB state that they have a shock proof socket. The manufacturer specifically makes the housing so that the socket has a little bit of play for vibration and road shock built in and they term that a shock proof socket. It just ensures the socket isn't mounted so rigid that the bulb has no give and shatters. This vibration dampening design helps the...
