Expert Answers about Wesbar

  • Incandescent and LED Lights to Replace Wesbar Amber Marker Light # 203367
  • The original part number you referenced, 203367, is the stock number for a light made by Wesbar, a producer of OEM and aftermarket trailer lighting. Their waterproof LED equivalent version, part # 47-203667, is indeed an exact drop-in replacement for the incandescent version. This light assembly uses a pigtail wire harness for connection, part # A46PB, and a rubber mounting grommet # 221588.

  • Is Tinned Wiring Used In Trailer Wiring Kits
  • The trailer wiring we offer like part # W002290, is designed to be used as a 5-wire harness, and works well with a trailer that has a surge coupler. The wires used in this harness are 16 gauge except the blue brake wire which is 18 gauge, and designed to be able to safely handle the current from a 12 volt system. The wires in this harness are not tinned. From my research I found that tinned wire is normally used in industrial wiring and used when the operating temperature of the wire...

  • Parts Included in Wesbar Replacement Lenses for Wraparound Tail Lights # W003372-73
  • The two Wesbar replacement lens products you referenced, # 105825-26 and # W003372-73, are both intended for their wraparound tail light 403028. Part # 105825-26 consists of just the two red lenses and part # W003372-73 consists of the red lenses plus the clear lenses for license plate illumination. The clear lens installs in the bottom side of the main fixture to shine down on the plate and the red wraparound lenses install on the main part of the fixture. If you are using a light other...

  • Recommended Way to Re-Wire a Boat Trailer with a 7-Way Plug
  • The adapter will work but it's more of a short term solution because of the potential corrosion issues in the future not to mention when you introduce additional connection points problems can arise. I would test the reverse lockout (purple or blue wire) with a circuit tester with the 7-Way center pin. If that works you are good. I would recommend rewiring the trailer with a 7-Way plug because it will prove to be more reliable than using an adapter. I would start with a trailer junction...

  • Troubleshooting Why Trailer Lights Go Out When You Hit the Brakes
  • It sounds to me like you may have a ground problem. There are several places to look for a poor ground connection. I recommend starting with the trailer connector on the trailer. Check to make sure that the ground wire is secured to a clean metal surface on the trailer. In addition, each lamp/signal will also need to be grounded. Typically the lamp/signal is grounded through the mounting bolts having direct contact with the trailer frame. If the area that the lights are mounted to...

  • 2-Pole Wiring Extension for Use with the Waterproof Over 80
  • Sounds like you are looking for the Hopkins 2-Pole Flat Wiring Extension # HM47965 to go along with the Waterproof Over 80" Low Profile Tail Light # 106411. The left hand version of this light is part # 106410. Or it is possible you are looking for quick splices like part # 564.

  • Recommended Rectangular Trailer Lights for my Snowmobile Trailer
  • At this time we don't have a tail light that measures 9-inches x 2-1/2 inches. The best match we currently stock is the Wesbar tail light right hand side # 106411. The left hand side tail light is # 106410. These are surface mounted tail lights and measures 8-1/16 inches in length x 2-7/8 inches in width. Additional close matches are Optronics drivers side # RVSTL61 and passenger side # RVSTL60. They are surface mount and measure 8-11/16 inches in length x 3-3/16 inches in width. I...

  • Replacement LED Wrap Around Lights For 1999 Rangertrail Trailer
  • I have attached a photo of the 7-Function LED Wrap-Around Tail Light, part # 271594 you can check out. The dimensions are noted on the photo. You can compare those to the lights you currently have on your 99 Rangertrail trailer and see if this will be a match. The # 271594 is for the right side of the trailer and for the left side you would want part # 271595, which is the same as the right hand but includes a license plate light. You should have no problem replacing your incandescent...

  • Why Does Driver Side LED Trailer Tail Light 271575 Cost More than the Matching Passenger Side
  • The driver side trailer tail light # 271575 has an additional function, the license plate light. So it and the right side, # 271574, are not the same. I have included a picture that shows the license plate light at the bottom of the driver side light.

  • Can Trailer be Wired for Backup Lights Using 5-Way Plug and then Converted to 7-Way
  • Yes, you could wire your trailer to have backup lights by using a 5-way flat like the Hopkins Endurance Trailer Connector, # HM47910, and then use an adapter like the 7 Pole to 5 Pole Flat Wired Adapter, # A57WB, to be able to plug in to your vehicle's 7-way. Although wiring the 5-way connector for backup lights and then converting to the 7-way will work, this will require more parts than what is necessary. I recommend just wiring in a 7-way connector like the Pollak Black Plastic, 7-Pole,...

  • Recommended Replacement 4-Way Connector For 1960 Trailer
  • We do offer flat 4-way trailer connectors. I recommend the Wesbar 4-Pole Flat Connector w/ Jacketed Cable, part # W787264. You would need to cut the connector off of your trailer and test the wires on the trailer for function using a 12-volt power source and a circuit tester like part # 3808. I recommend using a junction box like part # 38656, to protect the wiring. For ring terminals I recommend part # DW05702-1 for 14-16 gauge wires and part # 44-5310A for 10-12 gauge wires. I...

  • Replacement 5-Way Flat Trailer Side Connector for a Boat Trailer
  • It sounds like you have a version of a 5-Way flat wishbone harness like # W002290. A wishbone harness will have 2 running light wires attached to one running light pin. White is ground, the two brown wires are for running lights, yellow is for left turn and brake lights, green is for right turn and brake lights, and blue is for a reverse electric lockout solenoid. Since the wires on your trailer do not match up you would have to trace each wire back to determine the functions. Or...

  • Troubleshooting Trailer Right Stop/Turn Signal and Running Lights Not Functioning
  • At worst it sounds like you blew a fuse if after you connected the red wire from the part # 403356 to the brown wire from your trailer. The brown wire of your trailer wiring is most likely the running light circuit and would get connected to the brown wire of the # 403356. One thing you can do is test the trailer wiring connector of your tow vehicle for voltage with a circuit tester like part # 3808. You will need a buddy to apply the taillight functions while you test the connector....

  • How Does Wesbar Clearance Light LED Amber with Reflex Ground to a Trailer
  • You will just need to ground the external white ground wire on light # 47-222012. If you do not have the matching connector for the one on the light you can cut it off and attach a ring terminal.

  • Square Trailer Tail Lights with a Plug Connector for a Shorelander Trailer
  • All of the similar trailer tail lights like # 2423056 either have blunt cut wires or you just insert the wiring to the backs of the lights. None have a plug. What you could do is use light # 2423056 (and # 2423006 for the left side) and splice the plug from your old lights to them. You would need to make sure the connection is water tight by using some heat shrink tubing such as # DW05744-5.

  • Troubleshooting Trailer Lights That All Go Off When Brake Pedal Is Pressed
  • The problem you are having with your trailer lights sounds like a ground wire problem. The first thing I would check is the wires. Look for any place you have a loose ground or if there is corrosion or dirt present that would not give you sufficient ground. If you have a tilting trailer bed or tongue you will need to run a jumper wire from the tongue to the trailer bed to make sure you have a solid ground. The next thing I would suggest to check is the harness you are using. You will...

  • Are Wesbar Trailer Lights # 403076 and # 403026 Matching Left- and Right-Hand Lights
  • Yes, you are correct that the two Wesbar submersible trailer lights # 403026 and 403076 that you referenced are intended for use with one another. A product video is linked for you. The screws may appear to be different colors due to variations in the lighting during photography.

  • Matching Light to Go with Wesbar Stop/Turn/Tail/ # 2423056
  • The part number you referenced, # 2423056, is a trailer tail light. This is the right hand side (passengers side). The matching left hand side is # 2423006. The left hand side has a light at the bottom to illuminate a license plate.

  • Old Trailer Wiring 5-Way had 6 Wires But New 5-Way Has 5 Wires
  • The trailer connector that you had is what is called a wishbone harness. It has 2 running light wires so you do not have to run a jumper wire for running lights from one side of the trailer to the other. Wesbar harness # W002290 is an example of a wishbone 5-Way. All you have to do is connect the 2 running light wires from the trailer wiring together and then to the brown wire on the new harness. Or, if you are replacing all the wiring, you would run a jumper wire from one side of the...

  • Are Wesbar Trailer Tail Lights 403026 and 403076 Waterproof
  • A light that is waterproof is sealed. The bulb inside Wesbar light # 403026 is actually # 763560. This is a watertight capsule so water cannot get in. The limiting factor will be the wiring. When connections are made you will need to use heat shrink tubing such as # DW05744-10 to keep water out. Lights that are submersible have openings that water can drain out of. Any light that indicates it is sealed would also not be a problem for marine environments. The Wesbar lights you have...

  • Availability of Bulb and Socket Taillight Kit for Flat Towed Vehicle
  • It sounds like you're speaking of a bulb and socket kit like part # RM-155 from Roadmaster. Installation involves drilling a 1 inch diameter hole into the backside of your taillight assemblies and inserting another bulb. A wiring harness would run under the vehicle to the front, where the harness ends in a 4-pole connector to plug into the trailer connector on the tow vehicle. Keep in mind, not every vehicle will have enough room in the taillight assembly to allow for an additional bulb....

  • Car Hauler trailer Wiring
  • For you to retain the functions of the electric brakes on your car hauler trailer you will need to use a connector that will carry the power for all of the functions from the vehicle. For what you are doing you would be better off using a 7-Way Molded Trailer Wire Connector # H20046 since it has all 7 circuits and the brake output circuit wire has 12 gauge wire. I have attached a video that shows how to replace the 7-pole connector you can check out.

  • Replacement Tail Light for Obsolete Wesbar Trailer Tail Light 403028
  • The Wesbar tail lights that are associated with lens kit # W003372-73 were made obsolete on 3/25/2011. You could replace them with a similar LED version, # 271594 for the right and # 271595 for the left side.

  • 7-Way Plug and Lead Recommendation for a Trailer
  • The Coiled Adapter # 787196 has 5 wires that run through it. A ground wire, a running light wire, a left stop/turn wire, a right stop/turn wire, and an auxiliary wire usually run to the reverse light circuit of a vehicle. For what you are doing you would be better off using a 7-Way Molded Trailer Wire Connector # H20046 since it has all 7 circuits and the brake output circuit wire has 12 gauge wire instead of the 16 gauge wire of the # 78716 which would not be sufficient.

  • Can Wires on Wesbar Trailer Tail Light 403075 be Spliced to Trailer Wiring
  • Yes, you can splice the wires on the Wesbar trailer tail light # 403075. Since the light is going onto a Sea Doo trailer and will likely get submerged you will want to make sure the splices are water tight. I recommend using some liquid electrical tape # SWC50122 and heat shrink tubing # DW05451 to keep out water.

  • Is Wesbar Submersible Low Profile Trailer Tail Light 403076 Available in an LED Version
  • For replacement LED tail lights with the same design and dimensions as the lights you have you can use # STL16RB for the right hand side and # STL17RB for the left hand side. The difference is that the left hand side has lens on the bottom to light a license plate.

  • Is Quick Connect Available On Submersible Low Profile Trailer Lights
  • We have a couple of options for submersible low profile lights that may work for you. None of the lights we offer have the 3 prong adapter similar to the connector you show in the photo you sent. The low profile light I recommend is part # 403356. This is a submersible light that has replaceable light bulbs. For the low profile light that does not offer replaceable bulbs you would order part # 763560.
