Expert Answers about Optronics

  • 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 bat

  • Can a CB Radio Hook Up Via the Cigarette Lighter Port Using Optronics Adapter # A-200
  • The standard hook up via the cigarette lighter are +/- which correspond to your red and black wire, respectively. By connecting your black wire to the negative port of the connector, that will serve as your ground. It is possible that your cigarette lighter circuit may not have a high enough amperage rating to power your CB radio. Your vehicles owners manual should have the accessory outlet amp rating for the cigarette lighter listed.You will have to compare that value with the value of w

  • Left Side Boat Trailer Tail Light Does Not Have Power when Bulb is Installed
  • The most likely problem is going to be a bad ground. Without the bulb in, there is no draw on that light and ground issues normally show up when there is a load on the system. If you recently install a plastic license plate holder in between the light housing and the trailer frame, that can cause this problem (if the lights ground through the mounting studs). The solution will be to run jumper grounds (no matter how the lights ground to the frame) to the main trailer connector ground. This is

  • When Installing Optronics # STL22RB,The Right Rear Running Lights Work But Stop and Signal Do Not
  • To determine why your stop and signal lights do not work we have a process that can give some direction. First, we have to determine if the issue lies in your truck or your trailer. To test the truck, use a circuit tester such as Draw-Tite # 40376, and test the pin in question. I have attached a short video showing the testing process. If you find the pin without voltage when the corresponding function is activated, there lies your issue. If all of the pins check out with voltage on your

  • Compatibility of Tow Ready 7-way to 5-pole Adapter # A75TB with 2103 Toyota 4Runner
  • The Tow Ready 7-way to 5-pole adapter that you mentioned, part # A75TB is not a vehicle specific item. As long as the 7-way on your 4Runner is fully functional, in most cases the adapter will work just fine for you. If your 4Runner has a bulb out sensor that warns you when you have a burned out taillight, and you are towing a trailer that uses LED taillights, you will need to use an adapter that has a load resistor installed in it, like part # TR20141. Either adapter can also be used wit

  • Will Optronics Turn and Tail Light # STL78RB Need Additional Power Source on 2013 Toyota Camry
  • To use the Optronics 6-1/2-Inch Turn and Tail Light # STL78RB with your 2013 Toyota Camry, you will not need an additional power source. Each of these lights draw draw a fraction of the power of incandescent bulbs and are DoT-compliant. This item would connect using 3 wires: Turn signal and brake (red), tail light (black), and ground (white). I have provided a link to a video review of this product. To hook the Optronic light to your vehicle, I recommend the Tow Ready Custom Fit Vehicle W

  • The thread diameter of the mounting post on the Dual-Face LED Optronics Light # STL53ARPB is 1/2 inch. I spoke to my contact at Optronics to confirm this. The white wire is the ground wire, the black wire will be the tail light circuit and the red wire will be the stop/turn circuit.

  • How to Wire up a New Trailer Connector on a 2013 Sundance Travel Trailer
  • To eliminate all the guesswork involved in rewiring a trailer connector to your trailer I would recommend you make a jumper wire from a 12 volt battery (a vehicle battery would work great for this) and run 12 volts to each of the wires from your trailer to see for certain what circuit that wire carries. It looks like the wires from your new connector are the standard wire colors but just in case I attached a photo of how a trailer 7-way should get wired. I also attached an FAQ on wiring f

  • What Adhesive To Use When Replacing Clearance Light on 1987 Itasca Motor Home
  • I would recommend using a sealer so there is minimal chance of moisture seeping behind the light fixture. I recommend Fastenal TremPro 644 Silicone Sealant # 0160297. It creates a waterproof seal at seams between joined parts and adheres to nearly anything. Be sure to remove any old silicone or adhesive to the area prior to the application of the new silicone.

  • Availability of a Oval Trailer Clearance Light with a Black Base
  • The closest thing we have to a version of the Oval LED Trailer Clearance, Side Marker Light # MCL31RB that you referenced with a black base in an amber and red lens would be the Red Oblong Trailer Clearance, Side Marker Light # MC31RB and the Amber Oblong Trailer Clearance, Side Marker Light # MC31AB. Both these lights have black bases, but they have incandescent bulbs instead of LEDs.

  • 4-way Extension Recommendation for Use with an Optronics Light Kit # TLL36RK
  • What I think would make the most sense for you to do would be to get a 4-way extension piece to give you a little more wire so that you could install the Optronics Trailer Light Kit # TLL36RK. It sounds like you would probably need about an additional 5 feet of wiring, so for that I would recommend you get a Draw Tite Wiring Extension # 18045. This basically is a 4-way extension that will give you an additional 5 feet of wiring and should do the trick for you. If you wanted to, you could use

  • LED Trailer Light Kit with 4-Way Wiring Harness
  • Some trailer lights are for the driver side (left side) of a trailer because they include a license plate light. Others do not have this extra function so they could be used on either side. Individual lights are sold by themselves and do not include wiring unless the wiring is attached to them. We do have several LED trailer light kits that do include the wiring you will need. I have included a link to them for you to view.

  • Construction and Dimensions of the Optronics Sealed 3-Light Light Bar # MC93AB
  • The black base of the Optronics Sealed 3-Light Light Bar, # MC93AB, is made of plastic and the overall dimensions of this light bar is 16 inches long x 1-7/16 inches wide x 1-5/8 inches deep. If you were interested in a 3-light bar with a metal base and amber lenses, I recommend looking at part # MC99AB. This light bar has a white metal base and the overall dimensions are 15-1/16 inches long x 1-3/8 inches wide x 1-7/16 inches deep. I made a short video with these light bars for you.

  • Vehicle Bulb Out Sensor Goes Off When Towing a Trailer with LED Lights
  • The bulb out sensor indicates that you may have a BMW, Volkswagen, Porsche, AUdi, or other German vehicle. These vehicles have a problem when towing a trailer with LED trailer lights. The problem is what you have described. The LED lights do not draw enough power (in this case it is just the blinkers) and it makes the vehicle think there is a bulb out. The fix is to use a special adapter, # TR20141, which will eliminate this problem because it adds load resistors that increase the draw on the

  • Replacement Trailer Light Lens for an Optronics or Custer Square Trailer Light
  • The lens you have there in your picture sure does look like it fits an STL2, 3, 8, or 9 series Optronics light; same as replacement lens # AL8RB-1G. And if you check your light housing that information may be present. Based on your measurement though you may have Custer lens # LTL-LENS which is 4-1/2 inches across, 1/16 of an inch off from your measurement. To determine if the Custer lens will fit, measure the distance on center between the mounting holes. If its 3-3/4 inches then the Custer

  • How to Replace Optronics Taillight Part # STL70RB on a Cargo Trailer
  • If your trailer has flush mount lights like the Optronics Sealed Oval LED Tail Light, # STL70RB, then I have two ways for you to remove your old taillights from your Haulmark Cargo Trailer. These taillights are sealed, therefore, you need to change the entire assembly, not just the bulbs inside. If you have access to the backside of the light from the inside of your cargo trailer and your lights are hardwired, then you need to cut the wires close to the old taillight and gently push it from t

  • Can Optronics LED Trailer Light, Part # STL79RB, Replace Tail Lights on 1996 Chevy S-10 Pickup
  • The Optronics LED 3-Function Trailer Light, Part # STL79RB, is intended for use on a trailer to provide stop, turn and tail light functions. It is not intended for use as a replacement tail light on a vehicle, although this sort of application is not uncommon. You might want to check with your local DOT or highway patrol just to confirm that using these and separate amber bulbs for turn signals, as you intend to do, is legal in your state. Since your 1996 Chevy S-10 Pickup uses a combined li

  • Difference in Brightness Between # BUL10CB Backup Light and # BUL72CB Utility Light
  • Both the # BUL10CB and the # BUL72CB are 10 diode lamps, and therefore neither lamp would really be brighter than the other. The main difference between the two is how the light is focused. Because the # BUL10CB lamp is DOT compliant as a back-up light, the light would be more diffused over a wider area. By contrast, the # BUL72CB which is NOT certified as a back up light would have the light more focused on a smaller area. Each lamp would output a similar amount of light, but the # BUL72CB woul

  • 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 on you

  • Right Side Trailer Lights Not Working After Installing a Wiring Harness on 2011 Mitsubishi Endeavor
  • A poor ground connection could cause one side of your trailer lights not to work. I would start by checking the ground connections on the trailer since the wiring harness that you purchased does not have a separate ground wire. The ground connections on your trailer should be clean and corrosion free. Check the ground connection for the trailer connector as well as the grounds for the trailer lights. You could also inspect the trailer side connector for any corrosion and clean or replace as nece

  • Can 3 Sealed, Mini Rectangular LED Trailer Clearance, Side Marker Lights, # MCL95AB, Wire Together
  • You can wire 3 of the Sealed, Mini Rectangular LED Trailer Clearance, Side Marker Lights, # MCL95AB, to a single power source by splicing all three power wires together then going to a common power source. This would mean only having to make one splice rather than multiple splices like you have described and the lights would work much better. You might just need a little extra wire # 12-1-1 to reach. This wire is sold in 1 foot increments. I have included a link to a video review of the ligh
