  • Troubleshooting Dimming Trailer Lights When Braking And Using The Turn Signal
    Hi Doug, Based on the symptoms you're describing it just sounds like you're dealing with a lack of power. Everything works until you start putting too much of a load on the harness. Does your Suburban have a factory tow package/7-way or did you have to install one aftermarket? Older vehicles used to pull power from the vehicle tail lights to power the trailer lights and ended up drawing too much power and causing the lights to dim. In this kind of situation you can either replace the wiring...

  • I Installed the Standard Trailer Light Kit with 25' Wire Harness and Lights are Not Working
    Hello Matt, I am sorry to hear that you got the Standard Trailer Light Kit with 25' Wire Harness # TL29BK installed on your trailer and the lights are not working. It is hard to diagnose the problem without seeing the install. Can you pleases respond to the email you receiver with pictures of the whole install? I attached an install video for you to check out, maybe watching it you will be able to see what needs to be fixed. How did you test the lights? Just trying to figure out if...

    A light kit like the Optronics Trailer Light Kit, part # TL29BK, for your trailer is a fairly simple installation if you have average mechanical abilities. I am including a link to a video of the light kit being installed on a trailer and another video of a review on the light kit. These videos will help you with the installation process. Also, I am including a link to a FAQ page on trailer wiring.

  • 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 along...

  • 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 have...

  • Parts Needed to Completely Re-Wire 20-Foot Cattle Trailer with Light and Reflectors
    The cost to re-wire your 20-foot cattle trailer depends on the type and number of lights you choose to install. How many lights you legally need depends on the width of the trailer. A good place to start your project is the linked article on trailer lighting. This explains the lighting requirements based on the trailer's length, width and weight. We offer basic light kits like # TL29BK that are a cost-effective all-in-one option. If your 20-foot trailer is less than 80-inches wide you...

  • How to Wire the Lights in the Optronics Tail Light Kit # TL29BK
    Installation of the wires into the Standard Trailer Light Kit with 25 foot Wire Harness, item # TL29BK, is fairly simple, plug the corresponding wires on the # TL29BK kit into the upper (larger) holes on the back of the taillights. There are two holes for tail/brake lights and running lights. These holes are labeled. The wires should be stripped prior to insertion. The yellow wire goes on the left and is inserted into a tail/brake light port and the brown wire is inserted into a tail light...

  • 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...

  • 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...

  • Troubleshooting Utility Trailer Running and Side Marker Lights Not Working
    If the running lights and side markers aren't working at all on your utility trailer, then the first thing you will want to do is test the running lights pin on your tow vehicle's connector. Use a circuit tester like # PTW2993 to test the pin while the running lights are activated in the vehicle. If you get power, there then you know the problem is on the trailer but if you don't then there's an issue on the vehicle side. If you didn't get power the most likely culprit is a blown or missing...

  • Wiring a Trailer with the Optronics Trailer Light Kit
    First, you will need to use the 4-Way trailer side connector with the 25 foot loop of wire, included in the Optronics Trailer Tail Light Kit, item # TL29BK. Of the five wires present, the white is the ground, the yellow is the left turn/brake signal, the green is the right turn/brake signal, the yellow with brown stripe is the left running light signal, and the green wire with brown stripe is the right running light signal. You will need to run the yellow wire to the left side light, the...

  • Wiring a 2011 Victory Motorcycle and Trailer for Towing
    For simplicity, I would recommend wiring the motorcycle trailer as a vehicle trailer would be. A powered converter wiring kit, like part # C59496, would be connected to the motorcycle, which would provide a 4-pole trailer connector. The converter combines the brake lamp and the directional signal onto one circuit. The 4-pole connector utilizes four circuits, the white wire which is the ground, the green wire carries the right turn and brake light combined on one circuit, the yellow wire...

    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...

  • Wiring Single Wire Clearance Lights on an Enclosed Trailer
    You will need to use a circuit tester, item # PTW2993 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 taillight 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...

  • 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 the...

  • Is There Difference Between Optronics Taillight Kits TL5RK and TL29BK
    The Optronics kits part # TL5RK and # TL29BK are both very similar. Only real difference is there is a slight housing design difference between the two main taillight assemblies with the # TL29BK having the more recent design. Both are great kits that will hold up really well, better than what came on your Harbor Freight trailer for sure.

  • 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 and...

  • How to Attach a Trailer with a 3-Way Connector to a Vehicle with a 7-Way Connector
    A 3-way trailer connector is extremely rare and they really do not make any sort of adapter that will allow you to use this trailer connector with a 7-way connector. The only option that I have for you would be to replace the 3-way trailer connector with a 4-way trailer wiring harness and then use a 4 to 7-way trailer connector adapter. It is required by law in most states that your trailer has turn, brake, and running lights therefore if your current trailer's lights do not have these...

  • Lighting Requirements for an 8-1/2-Foot Wide Trailer for Use in California
    You came to the right place. There are very specific requirements for trailer lighting that depend on the dimensions and gross weight of the trailer. Trailers over 80-inches wide - including yours - have very specific minimum requirements for clearance and marker lights. The linked article explains these requirements in complete detail, with diagrams, and it even includes links to get you to the right items. I have also provided a link to the main product page for trailer lights. You...

  • Ways to Install New 4-Pole Trailer Connector
    Four flat trailer wiring, also called 4-pole wiring, uses four wires and pins configured as shown in the linked photo of a trailer side 4-pole connector. The one pin that is different from the other three (on both trailer and vehicle side connectors) will be the ground pin and this usually has a WHITE wire that will ground to a clean bare metal spot the trailer frame with a ring terminal. The next pin is for the running light circuit and this typically uses a brown wire to activate the...

This wire provides the ground connection from your tow vehicle to the trailer once that is done all of the light ground themselves to the trailer through the metal studs used to connect them.

  • 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.

  • 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.
