Expert Answers about Peterson

  • Troubleshooting Right Turn Signal Not Working on Trailer Taillights
  • First, disconnect the trailer from the tow vehicle so you can check the vehicle side connector. Using a circuit tester like the Quickee # 3808, test the functions of the connector; specifically check the right turn/brake, to make sure the signal is making it to the connector. If it is not working at the connector, there might be a fuse blown or missing in the power distribution box under the hood. Also, make sure both connectors are clean, and free of any dirt or corrosion. This very...

  • How to Replace Blown Tail Light Bulb on Trailer
  • There are a wide variety of trailer lights offered and these come with different type of construction. Some lights may not be user-serviceable (such as some LED types and sealed waterproof lights) but usually trailer lights that use standard incandescent bulbs have either a removable lens that either snaps into place or that is held in by screws. Examples of such lights are # ST51RB and # 432200. You can use the link provided to see all trailer tail lights offered. You can use the filters...

  • Replacing Bulb on Peterson Square Trailer Tail Light # 432400
  • To change the bulbs in Peterson trailer tail light # 432400 you will first remove the main lens which is held on by 4 screws. The main bulb can be removed by pushing down and rotating the bulb counterclockwise. There is a diagram on the inside of the case that explains this and it says turn it 30 degrees then pull up. I had to turn it several more times when I played with the light so it probably varies slightly. To install a new 1157 bulb # 30-90-157 you will line up the lower nub...

  • Troubleshooting a Right Turn/Brake Signal on a Pop-Up Camper Trailer
  • It sounds like the problem is in the way the your right turn/brake light is grounded. You said that there is power to the fixture which would mean that either the fixture/bulb is faulty or the ground is bad. Try finding a grounding point that is closer to the fixture and attach it there. Any paint-free metal surface that is clean should work well, you might try taking some sandpaper to the area to really clean it up and allow for the best possible contact. It sounds like you already...

  • Replacement Lens For PM 440 151
  • The Peterson Replacement Lens, part # 55-15R, would be the correct lens you are looking for. The lens measures 2 inches by 2-3/4 inches. The distance between the mounting holes is 2-5/16 inches. The mounting screws are included. I have attached a photo with the dimensions shown. Another note is this replacement lens fits Peterson Square Trailer Tail Lights (432200 and 432400). Screw holes are located beneath original tail light side marker lenses for use with this replacement lens...

  • 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...

  • Submersible LED Trailer Lights for Boat Trailer Over 80 Inches Wide
  • The Peterson Piranha part # 168A is one of our submersible trailer lights so it will be safe to use on a boat trailer. We carry almost 100 submersible LED trailer lights and I will provide a link to a page that has them all. You could use a number of different lights to go between your trailer taillights. You could use part # 168R which is a red version of the light you asked about. We also have long light bars like part # MCL70RB that will cover more distance of the rear face of the...

  • How To Wire the Peterson Round Trailer Tail Light # 431800 to a 4-Way Trailer Connector
  • A 4-Way flat connector has the white wire for ground, brown wire for running lights, yellow wire for left turn and brake, and green wire for right turn and brake. The Peterson Round Trailer Tail Light, part # 431800, is a three function light and has two wires coming out of the rear. The brown wire is for running lights and the red wire is for turn signal and brake. The light is grounded to the trailer by the mounting studs on the light. The lights have to be mounted to the metal trailer...

  • Why are Both of My Blinkers Blinking on My Trailer When Either Blinker is On
  • It sounds like there is a short between the yellow (left turn) and green (right turn) wires on the trailer light circuit that is causing both blinkers to blink when either blinker is being used. I would check the wiring and look for any exposed wire or obvious shorts on the trailer wiring that may be causing this problem. If you still can not find the problem I would use Circuit Tester, part # 3808, and first test the 4-way that is on your vehicle for intermittent voltage on the left...

  • Right Turn Signal on Boat Trailer Not Working, All Other Lights Do Work
  • To isolate where the problem is the first thing to check is the vehicle side trailer connector. Use a circuit tester such as # 3808 to test the pin for right turn/brake lights. If the brake signal function works but the turn signal doesn't then it could be a blown tow package fuse on the vehicle. If everything works on the vehicle then that leaves the trailer as the culprit. On a trailer the brake lights and turn signals are on the same circuit. So if the brake light is working then...

  • Troubleshooting a Fuse Blowing on a Trailer with Incandescent Trailer Tail Light Kit # TLK01
  • It sounds like there is a short that is causing an overload situation that is in turn causing the fuse to blow. The problem could be in a number of places, but I would start by checking the grounds on the trailer and on the truck. The ground for the trailer side plug should be attached to a clean, corrosion and paint free bare metal surface on the trailer frame. The lights ground through the mounting studs. They, too should be free of corrosion, dirt, and attached to a bare metal surface. If...

  • Troubleshooting Left Turn Signal on Wells Cargo Trailer Towed by Dodge Durango
  • I would begin by troubleshooting the trailer connector on your Durango. Have a helper activate the left turn signal, and use a circuit tester like part # 40376 on the connector pin that powers the left turn. If you have a 4-pole trailer connector, it is the pin fed by the yellow wire. If you have a 7-way connector, check the pin in the 9:00 position. With the turn signal active, the trailer connector pin should light up and blink along with the turn signal. This pin should also light up...

  • Right Turn Signal and Brake Light Not Working
  • It sounds like you either have a blown fuse or a short on the right side turn light and brake light circuit. First, I recommend checking the trailer wire connector on the vehicle. You can use a circuit tester, like # 40376, to test that power is coming from your vehicle for the right turn signal and brake light. The green wire on a 4-way connector is the wire that powers your right side turn and brake light. On a 7-way connector, the right turn and stop light wire is connected to the...

  • Replacement Options for a Sealed Trailer Light with a Bad Bulb
  • The Peterson 440 series trailer lights typically have 4 screws at each of the corners of the lens that allow you to remove the lens and replace the bulb. It may be possible that you have a sealed version of these lights, in which case the bulb is likely not replaceable without breaking the seal between the lens and the light housing. You will likely be better off replacing the tail lights. For a submersible light with a replaceable bulb and lens that is similar to the Peterson 440 series...

  • How Do You Remove The Peterson Replacement Lens, # 440-15R, On The Taillight To Replace A Bulb
  • The Peterson Replacement Lens, # 440-15R, is just the replacement lens, so it does not have any screws included. The screws that hold this lens to the taillight are on the taillight and use the holes that are in each corner of the replacement lens. It is a replacement lens for Peterson Square Trailer Tail Light Right Hand, # 432200, and the Peterson Square Trailer Tail Light Left Hand, # 432400. The taillights do come with bulbs.

  • Right Turn Signal and Brake Lights Not Working on Trailer Towed by a 2006 Dodge Ram 1500
  • It sounds like you have done a good amount of testing. Based on what you have said I would check the fuses and/or relays that are related to the trailer wiring on the truck. Use the legend on the lid of the power distribution box to find the locations. Make sure that the trailer is not also having problems by connecting it to another vehicle to determine if the lighting functions work. If they do not, it could be a bad ground connection or a short. Make sure the trailer and vehicle...

  • Availability of Replacement Side Marker Lens For Trailer Light PM440
  • You might look at Optronics Replacement Side Marker Lens, part # A2RB. This side marker lens is the same length and width as the Peterson Replacement Lens, part # 55-15R, you have referenced, but is 1-1/2 inches tall. The # A2RB lens will fit on a trailer light like the Optronics Square Trailer Tail Light, part # ST2RB.

  • Side Marker Lens Recommendation for a Peterson Taillight Assembly PM440
  • The Peterson Replacement Lens # 55-15R is the correct replacement side marker lens for your trailer lights part # 432200. Screw holes are beneath the original tail light side marker lenses for use with this replacement lens. In the manufacturing process, when the lights are being assembled, the side lights are snapped in via machinery, however, when they need to be replaced, they do need to be screwed into place.

  • Troubleshooting Trailer Wiring on 2008 Snowbear 6x8 Utility Trailer
  • The only difference between the run-of-the-mill 4 pole trailer connector and the one you describe is the fact that the one on your trailer split the running light circuit into two legs, one for the drivers side, using the yellow/brown wire and one for the passenger side, using the yellow/green wire. No worries about the length of your email, the more information, the better. When you mention that functionality of the lighting system changes with the running lamps on, it's a red flag...

  • Right Tail Lights on Trailer and Vehicle Stay Solid When Right Turn Signal is On
  • It sounds like you have a short somewhere on your trailer. I would recommend finding which wire is your right turn and brake wire at your trailer connector using a circuit tester like part # 3808 and follow that wire back to the tail light. My guess is that you will find a pinched, frayed or damaged section somewhere on that wire. You should also check all connections to make sure they are making good contact. It also would not be a bad idea to check the ground connections to ensure...

  • LED Trailer Clearance Lights are Dim on One Side of Trailer
  • I would recommend checking the running light circuit on your trailer. Specifically, check out the point where the circuit splits to run down each side of the trailer. I would be willing to bet that the 'leg' of the connection that runs down the side of the trailer where the lights are having issues is not completely secure. I would also recommend checking the ground connection point on the trailer. This is usually found on the trailer tongue. Make sure that this connection is securely...

  • Troubleshooting All Trailer Lights Blink when Using Turn Signal and No Brake Lights Work
  • That is a very interesting problem you are experiencing. The only thing I can think of would be to check the grounds of the light assemblies. Weak grounds can cause all sorts of problems and it could be that the tow vehicle that works with the trailer has a stronger ground circuit and the trailer works fine with it. Whereas the weaker grounds with the Expedition is causing all sorts of strange taillight behavior. Light assemblies can ground through the mounting hardware. You will want...

  • How to Ground a Mounting Stud Tail Light Mounted to Wood and How to Wire a Third Brake Light
  • There is a way to ground the lights from the Incandescent Trailer Tail Light Kit, part # 432800, if you were not going to mount them to a metal surface. You would want to use a ring terminal connector on the post that carries the ground circuit and then run a wire from there to a good, clean ground and the lights should operate. Once this is done it would not matter what surface you mounted these lights to. You could wire your 6 inch oval LED brake light to a new 4-way flat harness....

  • Rewiring a Car Trailer with Separate Turn Signals from Brake Lights
  • I can definitely help get you on track, but since wire colors on trailer wiring aren't always standard to a color code you will have to wire everything by function instead. Also, since he wants separate blinkers from stop lights he will have to install a converter for that like the part # C56196. I attached a chart that shows how this will wire to the trailer. The other picture I attached shows how a 7-way is typically wired on a trailer. The turn signal/brake wires will run from the...

  • Recommended LED Wedge Clearance Light For Trailer
  • The closest LED light that we have to the # M116A is the Triangular LED Trailer Clearance and Side Marker Light or Truck Cab Light, 15 Diode - Amber # CBL22AB. This has a wider design and is not reflective. This is a very nice light that I recommend if you are looking for an LED alternative to your current light. This is a submersible light. Unfortunately I think you will need to decide between LED and Reflective incandescent as you can't just change out the bulb on a sealed unit.

  • How to Wire a License Plate Bracket with a Light on a Dune Buggy
  • License plate lights are typically wired to the running light circuit. You should have no problem wiring your plate light in with your existing tail lights. I recommend using solder, # FL0803484, and a soldering iron for these connections, but a quick splice, # 564 will work if you do not have access to a soldering iron. A circuit tester, # 3808, will be needed to locate the running light circuit on the dune buggy. Typically it is easiest to find this circuit at the rear of the tail lights. We...
