• Troubleshooting Trailer Lights Going Out When the Brakes are Applied After Trailer Light Kit Install
  It sounds like you have a ground issue. When trailer lighting does not have a sufficient ground many different scenarios can show up, but the most prevalent is when the most amperage is applied, like tail lights on and brake pedal pressed, the lights go out. All lights must be properly grounded for proper function. When installing the standard trailer light kit, # TL29BK, the lights are grounded through the mounting studs. You need to make sure that the mounting studs are contacting...

• Wiring Single Wire Clearance Lights on an Enclosed Trailer
  You will need to use a circuit tester, item # 40376 if needed, to test the wires exiting the trailer to figure out the wiring configuration with the trailer hooked up to the truck and the running lights on. You will probably find that you have tail light power on one of the green wires and no power on any of the other wires. In this case you would wire the two green wires to the power wire coming from the clearance light. You would then need to wire the two white wires coming from the...

• How To Ground Trailer Tail Lights Without a Ground Wire To a Wooden Surface
  The Standard Trailer Light Kit with 25' Wire Harness part # TL29BK as I am sure you noticed grounds via the mounting hardware therefore there is not a singular ground wire. In order to attach this light to a wooden surface you will need to run a ground wire yourself up to the trailer tongue using the mounting studs on the back with ring terminals part # DW05705-1 and wire part # 12-1-1. The other option you have is to use the Peterson LED Light Kit for Trailers part # V944 which does...

• Availability of an LED Trailer Tail Light Kit that Will Fit a Snowmobile Trailer
  In terms of a pre-assembled kit with everything included, the closest we have to something with tail lights that are 2-1/2 inches tall would be the Trailer Light Kit with 25 Foot Wiring Harness, # TLL16RK. The included tail lights in this kit are 2-7/8 inches tall. Another option would be to get a couple of # STL76RB lights, and a 4-Way, trailer side wishbone wiring harness, # A35W42B. I have included a link to a video showing the installation of this wiring harness for reference.

• 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...

• How to Wire a Trailer for Tail Lights
  First, lets make sure you have all of the parts you need to wire a trailer for lights. If you have an old trailer and want to replace everything, I recommend using a kit like our Optronics Tail Light Kit, # TL29BK and our trailer wiring installation kit # HM51020. We also have an LED kit, # TLL9RK. Step 1 - The trailer connector should extend 2 - 3 feet past the tongue. Attach the ground wire directly to the tongue of the trailer using a self tapping screw # 101131802 and a ring terminal...

• Trailer Tail Light Kit with Brake Lights and Turn Signals on the Same Circuit
  Trailer tail light kit # TL29BK does work on a combined system meaning that the turn signals and brake lights are on the same circuit, which is what you want. You will not have the same issue with it. Please note that this light kit has lights that ground through the mounting studs. The mounting surface must be clean and free of corrosion and avoid putting anything in between the light and the trailer frame. If you do run into a ground problem then make sure that the vehicle side...

• Which Trailer Light Kit is Best for a Jet Ski Trailer
  Trailer light kit # TL29BK does not include submersible lights, so water would be able to enter the light housings. A better choice for your jet ski trailer would be a submersible light kit # TL5RK, as the lights will be sealed against water. I would recommend, however, that you unplug the trailer connector and let the bulbs cool down a bit before backing into the water, so that the cold water will not crack the bulbs. This is good practice, also, because it lets your wheel bearings...

• Instructions for Using Optronics Trailer Wiring Kit # TL29BK
  Optronics doesn't offer instructions for the # TL29BK trailer taillight kit. However, if you click the link I provided to the the trailer wiring help article, you'll see a wiring diagram showing how the kit would be used to wire a trailer. The wiring system shown in the diagram is more elaborate than what you'd have, so you'd ignore all the wire colors but the white, green, yellow and brown. The green wire feeds the right turn/brake lamp. From the front of the trailer, it would run...

• Trailer Keeps Blowing Vehicle Running Light Fuse or Trailer Running Lights
  The problem you are having with the running lights on the trailer sounds like a short circuit somewhere. To find it the first step is to disconnect the trailer from the tow vehicle. Then use a circuit tester such as # 40376 to test the vehicle side connector while someone sits in the vehicle and goes through the light functions. If the running light fuse blows while testing the vehicle side connector then that indicates the short is on the vehicle somewhere. Check the connections for...

• 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...

• Trailer Right Turn Signal Only Works when the Brake Lights are On
  This sounds like a ground issue and/or a short. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light but can show up any time. A short could be caused by corrosion or loose or damaged wiring connections. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean...

• Electric Brakes and Tail Light Wiring for Tandem Axle Trailer with Brakes on One Axle
  The wiring I would go with, based on your dual axle trailer with 1 axle electric brakes, is the 7-way molded connector (10 feet long) # 50-67-005. The wire is insulated which protects it well from the elements. I recommend getting a junction box like # 38656 because it makes it easier to diagnose problems when using a junction box. If you need wiring from the junction box to the brake assemblies, you can use duplex wire # 10-2-1. Protecting your wiring from corrosion and moisture is...

• Troubleshooting a Malfunctioning Atwood Trailer Light Kit for Use with 2004 GMC Canyon Pickup
  Lights will do all sorts of funny things if they do not have a proper ground. Some will work, some will work intermittently and some may not work at all. If you did not have the lights mounted to the trailer, the TL29BK Kits use stud-grounded lights, then the lights did not have a true ground. If you want to test them again, run a wire from the mounting studs on the lights to a good ground on the truck, usually the frame, or the ground post on the truck connector (white wire). Also,...

• All Trailer Lights Work Except Brake Lights Using Tail Light Kit # TL29BK
  This is most likely a bad ground. Ground issues normally show up when there is more load on a circuit such as the constant draw of brake lights. There are a few things that could cause this to happen. The first thing you are going to want to check though is the vehicle side connector to make sure the brake signal is reaching that point. Use a circuit tester like # 40376 if you do not already have one to test the vehicle side connector. If the brake signal is not coming through then check...

• New Trailer Light Kit Not Working with 2 Vehicles
  Since none of the lights of the light kit # TL29BK work I'm guessing the problem is with the white ground wire. Make sure it's grounded to a clean, bare metal surface on the trailer's steel frame. If your trailer has an aluminum frame then you need to run a wire from the connector's white wire back to the mounting studs of each light in order to get a good ground. As far as wiring goes the wires are green for right turn and brake lights, yellow for left turn and brake lights and then...

• How to Wire a Ground Wire to a Trailer Light that Grounds Through Mounting Hardware
  What you would want to do is run the white wire on your trailer's wiring to the ground screw area of the trailer light to ensure that the ground will be sufficient for the light. Then you would just run the power wire to the single wire of the light and you would be good to go.

• Tail Lights with Separate Amber Turn Signals for a Motorcycle Trailer
  We have lights that can have separate brake light/turn signal functions but they are large double and triple tail lights designed for RVs and would probably not be the best option for a motorcycle trailer. One possible solution is to use a set of regular tail lights such as # TL29BK, and then separate amber turn signals that are DOT approved as turn signals (the amber lights we have are DOT approved as trailer side marker or clearance lights). Although a beehive style light such as...

• Lighting and Conspicuity Tape Recommendation for a 36 Foot Long Trailer
  I attached a help article on trailer lighting requirements based on size of the trailer. Based on your dimensions you would want the # TLL36RK to start and then would also need a # MCL84RB and a couple more clearance lights like part # MCL95AB. You will also need conspicuity tape as well like part # RTR150711PB. See the mentioned help article for placement of the lights and tape.
