• Looking For Replacement Light Kit For Malone Microsport MPG460G
  Hey Mark, That is a great trailer so I am glad you are enjoying it! There are a couple routes you could go to replace those lights. We do not carry the full Malone replacement kit, but Malone does carry it. Their part number is #6341. I show that they do not have it in stock so I am not sure how quickly you would be able to get it to you. My recommendation would be to go with our kit # TL5RK. This is a light kit with everything that comes in the Malone kit as well. Its got both tail...

• All Trailer Lights Blink When Truck Headlights and Turn Signals are Turned On
  The wiring harness on the trailer side is what is called a wishbone harness. It splits the running light signal so that you do not have to run a jumper wire from one side to the other. The yellow/brown wire is for the left side running lights and the green/brown is for the right side running lights. That could be what the problem is if you wired it differently. Make sure that the trailer lights are grounded to a clean and corrosion free location of the trailer frame. Also check to make...

• Trailer Lighting Kit Recommendation for 16 Foot Trailer
  Hey Christopher, a 16 foot trailer like you have is almost guaranteed to not be over 80 inches in width which the Optronics Trailer Wiring Lighting Kit part # TL5RK would work great for. This comes with everything you'd need for your trailer to be legal from a lighting and reflector point of view. The lights are also waterproof too so there'd be no need to worry about towing the trailer in the rain. These are actually even submersible too so you could back the trailer in water if it happened...

• Trailer Lights Not Lighting Up Properly on Harbor Freight Trailer
  It sounds like the wiring harness you have is what is called a wishbone harness. These will have 2 wires that connect to the single running light pin, so you don't have to run a jumper wire from one side of the trailer to the other. It also sounds like you have everything hooked up correctly. Yellow is usually left turn and brake lights, green is usually right turn and brake lights, brown is usually running lights, and white is the ground. You can test this by connecting the trailer to...

• Best 4.80-12 Trailer Tires For Highway Speed
  Okay, let's go ahead and start with the best 4.80-12 trailer tires for highway speeds, and for that you want a radial tire because they run cooler and flex more than bias tires. The best option for this is a tire from Taskmaster: - Taskmaster 4.80R12 Radial Trailer Tire # TT48012C The # TT48012C has an 81 mph speed rating, the highest for this size tire, and is a load range C tire that has a 990 lb per-tire rating (so 1,980 lbs for two tires). As for a wheel and spacer, there really...

• Will The Peterson M540 Light Kit Fit A Bracket With 2-1/4" of Head Room?
  I measured from the center of the mounting studs to the top of the lights that come with the Peterson Light Kit # M540 and it is 2-1/2". Just to make sure, I also measure the Optronics Under 80" Trailer Light Kit with 25' Wiring Harness # TL5RK the same way, and they measure exactly the same, unfortunately. With that said, I may have another option available, but the lights will be completely different. If you look at the Optronics Trailer Light Kit # TL16RK, which technically is for trailers...

• Trailer Lighting/Wiring Kit for Snowmobile Trailer
  Standard 4-pole trailer wiring uses flat-style connectors, like part # W787268 which is a trailer-side connector and part # HM48044 which is the mating vehicle side connector. On these items and on the 16-gauge bonded 4-pole wire # 16-4B-1 you referenced in your question the usual pin/function assignments are the same. These are as shown in the linked photo and in the article on trailer wiring that is included for you. The one pin that is not like the others will be the GROUND pin which...

• Troubleshooting Running Light Circuit Not Working On Right Side of Trailer
  The blinker/brake lights are carried on one circuit and the running lights are on a totally different one. Since the stop/turn circuits seem to work on the left side but the running lights on that side do not you need to check the wiring of the running light circuit that runs to that side of the trailer and fix as needed. I attached a diagram of how a trailer is normally wired as well as a help article that covers troubleshooting trailer wiring as well.

• Trailer Light Kit for a 10 Foot Trailer
  Legally a trailer only needs right and left turn signals, brake lights, and running lights. The license plate light will be tied into the running light circuit. On a trailer, the turn signals and brake lights are on the same circuit on each side. So the minimum you will need is 4-wire bonded wire such as # 16-4B-1 that you have referenced. For a trailer side 4-Way you can use # A20WB and you would not need the wire by itself. This is a 20 foot length and the running light circuit is split,...

  There are different taillight requirements for trailers that are over 80 inches in width vs. ones that aren't over 80 inches in width. If you check out the link I attached you will see all of these differenced highlighted.

• 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...

• How Is a Trailer Grounded to a Trailer Hitch on a Towing Vehicle
  The trailer itself will have a ground wire from the trailer connector that needs to be attached to a clean and corrosion free bare metal surface on the trailer frame. The lights like in Incandescent Trailer Tail Light Kit, # TL5RK, will ground through the mounting studs. The truck side trailer connector will also be grounded to the vehicle frame. The trailer itself will ground through the coupler and trailer ball.

  I think the part # STL68RB would be perfect for your flatbed truck (looks good by the way). The dimensions of the this oval light are 10 inches long and 3 inches tall.

You might also be interested in the stainless steel trim piece part # A68SSB.

• Running Lights Not Working on Trailer After Installation of Optronics Trailer Light Kit # TL5RK
  There are many possible reasons why the running lights are not working on your trailer when using the Optronics Trailer Light Kit, part # TL5RK. First, I recommend checking the ground connections. The trailer lights on this kit will ground through the mounting studs. They will need to be attached to a clean and corrosion free bare metal surface. You will also want to make sure that the main ground from the trailer connector is attached to a clean and corrosion free bare metal surface....

• Troubleshooting Trailer Lights that All Come On When Key Is Turned On
  The issue you are having is the circuit you chose to power the running lights circuit of your trailer 7-way. If that circuit sees voltage when the key is turned on and your trailer is connected then all of the trailer lights will illuminate when the key is turned on. You need to find a circuit that only sees voltage when the running lights/head lights are on to run to the brown wire. The running light circuit of your truck should work well. I attached a couple help articles on trailer...

• 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.

• Recommended Suspension Parts Needed To Build A Smoker Trailer
  Looks like you have quite a project going here. After consulting with other Experts, the first thing I would recommend is a new axle for your trailer frame. It appears the axle you have was originally used on a car and welded to the trailer. I could not recommend any suspension that could safely be used with the axle in your photos. I have attached a help article that explains how to determine the correct axle position. The next thing to consider is that you will have to build your trailer...

• What is the Correct Wiring Needed to Re-Do Lighting on Trailer?
  The correct kit for your Shoreland'r PWC trailer is going to depend on its width. If it is over 80 inches wide, you will want the Over 80-Inch Trailer Light Kit, # TL16RK. If the trailer is less than 80 inches wide, you will want to go with the Submersible, Under 80-Inch Trailer Light Kit, # TL5RK. Each kit is going to come with tail lights, side marker and clearance lights, a wiring harness with 4-way connector as well as the mounting hardware. To make things easier on yourself, you may...

• Trailer Right Turn Signal Not Working When Connected to a 2000 Ford Ranger
  If your 2000 Ford Ranger has the factory trailer connector then there is a fuse for the trailer right turn and brake light located in the in cab fuse panel in location 7. But if this fuse is blown then the right brake light on the trailer also would not work. If you have an aftermarket wiring harness such as # 118344 then it ties into the tail light wiring on your Ranger. Otherwise you would have to follow the wiring as far forward as you can and fix any broken or pinched wires. I have...
