Expert Answers about Optronics

  • How to Change Tail Light Bulbs in a Submersible Trailer Tail Light
  • If you have a newer model Wesbar Submersible Low Profile Trailer Tail Light, item # 403076, there are screws on the inside of the housing securing the clear capsule to the light housing. Removing these screws will allow you to remove the clear capsule cover and replace the bulbs. When the clear capsule is replaced an o-ring seals the bulb. The replacement bulb is part # A1157B. The older Wesbar tail lights used factory sealed capsules to prevent water from getting to the bulb and socket....

  • How to Remove Flush Mount Taillights and Grommets in a Square Tube Snowmobile Trailer Frame
  • It sounds like your trailer has the 6-1/2 inch Oval stop turn and tail lamps and some side marker lamps that use a rubber grommet like the 6-1/2 inch oval tail lights grommet, # A70GB. Since the area where your lights are mounted is not accessible from the back side, you will need to pry the light out of the front of the grommet with a small screwdriver or other similar tool. If you could find a plastic pry tool that might work better and keep you from damaging the rubber grommet. Another...

  • How to Wire the Camping Travel Trailer Stop, Turn and Tail Light, # RVST50
  • The Camping Travel Trailer Stop, Turn and Tail Light, # RVST50, has a total of 3 wires. The white wire is the ground and needs to be connected to a clean and corrosion free metal surface. It sounds as if the clearance lights are using the turn signal function instead of the running light function. Usually, the running light function on a trailer is a brown wire. You can use a circuit tester, like the Quickee # 3808, to find the correct wire. This wire will split off at some point near...

  • How to Cut a Grommet Hole for Installation of the Oval Trailer Tail Lights # STL22RB
  • The easiest way to cut the oval hole for the Rubber Grommet, # a70gb, in my opinion, would be to use a Light Mounting Bracket for 6-1/2 inch Oval Trailer Lights, BK70BB, as a template and then use a hole saw the correct size to cut a hole on each end of the mounting location. Then, use a angle grinder with cut off wheel or a reciprocating saw with metal cutting blade to cut the straight top and bottom sides of the hole. The correct width for the grommet is 2-5/8 inches, but I have found...

  • How To Charge Trailer Battery On Dump Trailer Using The 7-Way Trailer Connector
  • You will want to use a circuit tester like the Quickee Tester, # 3808, and check the # 4 terminal on the back of the 7-way trailer connector on your trailer for power. This is the 12 volt power terminal so there should be power to that terminal. You will need to run a 10 gauge power wire like the, # 10-1-1, from the # 4 terminal (12 volt) on the 7-way trailer connector on the trailer to the positive terminal on the trailer battery. This will allow you to maintain a charge on your trailer...

  • Correct Wiring for Optronics LED Trailer Lights # STL22RB
  • To install the Optronics LED Trailer Lights, part # STL22RB, you will need to use the Straight 3-Wire Pigtail, part # A45PB. The Red wire of # A45PB will carry the turn signal function, the Black wire is for running lights, and White is ground. If you are referring to installing the lights on your vehicle, you would need to use a circuit tester, part # 3808 to test the functions of each wire. If installing on a trailer, I would recommend running new wiring from the lights to the trailer...

  • What is the Difference Between Over 80 inch and Under 80 inch Trailer Tail Lights
  • A trailer that is over 80 inches wide is required by DOT regulations to have rear clearance lights. An over 80 inch taillight kit, like part # TLL16RK, will have the side clearance light built into it. An under 80 inch taillight does not have the clearance light built in and an additional red, rear side marker light would be required if you used an under 80 inch rated light on a trailer that is over 80 inches wide. Using an over 80 inch taillight on a trailer like yours that is under...

  • Is there a Special Trailer Tail Light Bulb for Turn Signals, Brake, and Running Lights on One Bulb
  • Trailer tail lights have a combined circuit for turn signals and brake lights and a separate circuit for the running lights. Because of this type of system you would not be able to get all the functions on a single circuit. That type of wiring is fairly complex and is primarily found on German vehicles (Volkswagens in particular) but not all. But even on trailer stop, tail, and turn signal lights the functions are all on one bulb, sometimes 2 depending on the light. But there are still...

  • How to Wire Electric Brakes on a Tandem Axle Trailer
  • If your trailer has 7 wires running all the way back to the brakes, then yes, you can tap into the existing wiring. Each of your new brakes will have two wires for the brake magnet. One wire is for 12 volt power to the brake magnets and the other wire should be grounded either to the trailer frame or to the main trailer ground wire. It does not matter which wire is used for power or ground because they are not polarized. If the trailer wiring is running down the left side of the trailer,...

  • How do LED Sidemarker Lights Wire in to Trailer Light Wiring
  • When installing a sidemarker light such as this Optronics Trailer Light # MCL44AB you will want to splice into the signal wire for your trailer running lights circuit and then run the ground wire to a clean metal surface. The black wire will be the power wire and the white wire is the ground wire. I attached an FAQ on trailer wiring for you to check out also. I also attached a review video for this product for you to check out. This video shows how the light gets wired and looks when...

  • How Do I Convert My Incandescent Trailer Lights to LED Lights
  • Yes, you just have to remove the old lights, match the wires and mount the new ones. Please note, that it is usually not a good idea to mix LEDs and incandescent lights, so if you have have side markers or other lights on the trailer, make sure you switch those to LEDs as well. Incandescent lights draw much more amperage than LEDs do, and if they pull that current through the LED fixtures, the LEDs could burn up. We have LED side markers and clearance lights like part # MCL36AB and...

  • Replacement Submersible Tail Lights for a Shorelander Boat Trailer
  • First, the additional function is a license plate light. If your license plate is mounted and/or illuminated elsewhere then you could use 2 right side lights. When replacing trailer lights it is best to go with all LEDs or all incandescents. Mixing the types can result in lights not working or overdraw on the LEDs. Otherwise you can use either one. The dimensions, 6-1/16 inches long x 3-5/8 inches wide x 2-1/4 inches deep, for # STL56RB are correct. Rear reflex means that the lens...

  • How to Wire Reverse Lights on a Trailer with a 4-Way Trailer Connector
  • We do have a solution for you, however, you will not be able to power reverse lights on a trailer with a 4-pin trailer connector. The reverse lights on a trailer must receive power from the reverse lights on the tow vehicle. To do this, you will want to install a 5-pin connector on the trailer and on the tow vehicle. There are many options, but I recommend installing the Hopkins Endurance 5-way Flat Wiring Kit, # HM47890, for a uniform look. You can simply cut off the 4 pin connectors...

  • Load Resistor Recommendation for Use with LED Tail Lights on a Flat Bed Truck with Hyperflash
  • You will wire a load resistor into the wiring of each light socket that has an LED bulb and flashes. So basically you will need to wire a load resistor into any bulb that blinks or has a dual intensity feature that lights up when the brakes, blinkers, or emergency flashers are operated. To do this correctly, you will need to wire the load resistor on the positive wire and then either ground it to the ground wire of the bulb, or to a good frame ground. You will need to do this for all...

  • How to Activate Boat Trailer Surge Brake Lockout from the Factory 7-Way on a 2012 Toyota Tacoma
  • It sounds like you have a factory 7-Way connector on your 2012 Toyota Tacoma and that you also have the dealer supplied electric brake controller wiring harness for wiring an electric brake controller in the cab of your vehicle. Since your boat trailer is equipped with surge brakes, you will not need to install an electric brake controller in the cab of your Tacoma. The first thing you should do is check the center pole, see photo, in the 7-Way connector on your vehicle with a circuit...

  • What Is Hole Size For Mounting 2 Inch Round Trailer Lights With Rubber Grommet
  • The item you selected, Sealed 2-1/2 Trailer Light, part # MC57AB, is a 2-1/2 inch light that will mount into a 3 inch hole using 2-1/2 inch grommet, part # A55GB. The hole size to mount a 2 inch round light flush mounted would be 2-5/16 inches. The grommet you would need for a 2 inch light would be 2 Inch Round Grommet, part # A54GB. If you are flush mounting your lights, the 2 inch light will sit inside the grommet. A 2 inch light similar to the one you selected is part # MC53AB. We...

  • Trailer Brake Wiring for Tandem Axle Brake System
  • I'm not sure what the sensor you describe is for. Typically trailer wiring is color coded so that right turn and brake light signal is carried by a green wire, and the brown wire carries the running light circuit. The brake output circuit is usually carried by a blue wire which travels to each brake magnet, where it attaches to one lead from each magnet. The other lead from each magnet will ground to the trailer frame. I'll give you a link to a typical trailer wiring diagram. I...

  • Replacement Tail Light Lens on a Snowmobile Trailer with Optronics Tail Lights
  • If your tail lights look like # STL16RB or # STL17RB, then you can use the Replacement Tail Light Lens, # A16RB. This is the correct replacement if the tail light has incandescent bulbs. If it is an LED tail light, use # AL16RB. If the lens portion is deeper on your lights than those pictured, you may have a 26 series light like # STL26RB as an example. The 1/16 of an inch would be the very first tick mark after the 8 inch line on a ruler (provided the ruler measures in 1/16 increments)....

  • Turn Signals and Brake Lights Not Working After Installing LED Lights on a PWC Trailer
  • First make sure that the trailer connector is functioning properly with no trailer connector. Use a circuit tester to test the connection. If the brake and turn signals are not working without a trailer connected check to be sure there are no blown fuses on your vehicle and that the converter box has power if your vehicle requires one. Then on the trailer make sure that the wires are connected to the correct circuits, and that the white wire is properly grounded, at the trailer tongue...

  • Wiring Single Wire Clearance Lights on an Enclosed Trailer
  • You will need to use a circuit tester, item # 3808 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...

  • Trailer Wiring Issues with Running Lights Blinking
  • Step one is to isolate the problem to either your tow vehicle, your wiring harness or your trailer wiring. To begin, disconnect the trailer wiring harness from the towing vehicle. First focus on troubleshooting the trailer. Check the white ground wire from the trailer plug to ensure that you have a clean secure ground connection to the trailer frame. Internal trailer wiring can over time develop wear spots in the insulation that can create a dead short. Such a condition will quickly...

  • How To Order Trailer Lights
  • To order trailer lights you will want to order by part number on your lights or by the size of the light you will need. The SAE stands for the Society of Automotive Engineers and the 97 DOT stands for the Department Of Transportation. These part numbers are usually on the lenses of most all trailer lights. You will want to get a Brand name (Bargman, Peterson, Wesbar) and the part number (40-38-001, 154R, 221902) that is on your light to be able to get the correct light for your trailer....

  • Brake Lights Turn Off when I Step On the Brakes After Wiring New Trailer Lights
  • Yes, it seems like you have a ground problem on the trailer. I would start by checking the ground wire at the trailer coupler and making sure it is connected to a solid clean paint free spot on the coupler of frame. Then I would check the tail light assemblies. Tail lights are usually grounded through their connection to the trailer frame. If you have a plastic license plate bracket on the left side this could be the culprit. You should also check the brackets that hold the lights....

  • What Size Hole to Mount Optronics 6-1/2 Inch Oval Taillight # STL22CCRB
  • The # STL22CCRB lamp you referred to is typically mounted in a grommet, like part # A70GB, which in turn is mounted in a bracket like part # MNT-651SS. If you were planning on cutting a hole to mount the lamp and grommet, the hole will need to measure 6-3/4 by 2-1/2 inches, as you can see in the diagram I provided. The easiest way to cut the hole would be to use a 2-1/2 inch hole saw, and cut two holes 6-3/4 inches apart (measured outside-to-outside). You could then use snips or a rotary...

  • 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...

  • Looking for Replacement Trailer Lamp Lens # 1A-S-20
  • I was able to find the exact replacement amber (1A-S-20A) and red (1A-S-20R) lenses. I did a Google search on kaper2 (or Kaper II), and found replacement lenses. Their replacement lenses are shown as measuring 4 inches long, by 2 inches wide by 3/4 inches high. I pulled one of the Optronics # A32RB off of the shelf, and measured it using a dial caliper. I came up with 4.013 inches long, by 1.97 inches wide by .67 inches high. I suspect that in measuring their lens, Kaper II might very...

  • How to Determine the Amperage Draw of the 55-Watt Halogen Area Light with H3 Style Bulb
  • The 55-Watt Halogen Area Light, item # QH75ISB, draws 4.5 amps per light. There is an equation we can use to determine amperage when watt rating and input voltage is known. Amperage equals Watt Rating divided by Input Voltage which is typically 12.8 volts in automotive applications. So 55 watts divided by 12.8 volts equals 4.30 amps and your specific charging system may output slightly more than 12.8 volts. If you wire this light with a switch you should be able to use it on your trailer...

  • Connecting 5 Wires From a Trailer to a 7-Way Trailer Connector
  • The best solution for your situation would be to use a circuit tester, like part # 3808, to wire your trailer wires to a seven way trailer connector, like part # A7WCB. Wiring by function is the best way to make sure you have the trailer connector wired correctly. Be sure you know what the black wire function is on the trailer. It will probably be for a twelve volt battery or for reverse lights, but it could be used for something else. The location for the black wire in the connector...
