  • Trailer Right Turn Signal Only Works when the Brake Lights are On
  • This sounds like a ground issue and/or a short. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light but can show up any time. A short could be caused by corrosion or loose or damaged wiring connections. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean...

  • Replacement Trailer Taillight Lens that is SAE Number 2 AS2T2I6
  • We do indeed carry Optronics products. The number you provided is a DOT reference number, and does not denote the part number of the lamp or the lens. However we had a picture sent in once from a guy of the housing of the light he needed a lens for plus the number you listed and we found that he was looking for the # AST60B. Does your light look like the part # RVSTL60? If so then you would need the part # AST60B.

  • Recommended Side Marker Lights for EZLoader Trailer
  • I can help you find the correct parts for your EZ Loader trailer. Based on the photos you submitted, the # AL91RB will fit your style connector on your trailer. The amber light is # AL91AB, and the grommet you will need is # A91GB. All these items come in quantity of 1 so you will want to adjust the quantity on the grommets page to 2. I have linked all the above products to this page for your convenience.

  • Roof Clearance Light Recommendation for a 2015 Ford F-150
  • The Clearance Light Kit # CB-15AK is a universal roof light kit that could be made to fit a 2015 Ford F-150. It would require a custom install though since the roof of this vehicle is not setup from the factory for lights like this.

  • Method of Bulb Replacement on Oval Red Grommet-Mount Trailer Taillight
  • Usually a grommet-mount incandescent tail light will be pressure-fitted into the grommet and held there simply by friction from the rubber. If there are no visible screws to allow lens removal and no accessible portion of the light's rear surface then its almost a sure thing that you'll just need to carefully pop the light out of its grommet. Ideally you'll have a tool that is strong enough to flex the grommet material but not so hard that it can damage the lens or base. The light in your...

  • How Can I Get Trailer Lights to Flash when Disconnected from Truck
  • If your trailer happens to have LED lights on it then what you could do is use a separate car battery and a couple of Custer strobe drivers, # STR-MRLY or # STR-QRLY, and connect the output wires to the trailer connector wires as needed. This driver is only rated for 420 milliamps though so only about 2 LED lights be driver would work. And if the trailer has regular incandescent lights then it will not work because the power draw would be too high. Another simple option, battery powered...

  • Availability of Replacement Lens for Magnetic Tow Lights
  • I compared the picture of the lights you have to the magnetic tow lights we carry and it looks like you have the Roadmaster Magnetic lights part # RM-2120. Which I spoke to my contact at Roadmaster and he said that any replacement lens with a 4-1/4 inch overall diameter that snaps onto the light housing would work like the part # A24RB.

  • Lighting and Conspicuity Tape Recommendation for a 36 Foot Long Trailer
  • I attached a help article on trailer lighting requirements based on size of the trailer. Based on your dimensions you would want the # TLL36RK to start and then would also need a # MCL84RB and a couple more clearance lights like part # MCL95AB. You will also need conspicuity tape as well like part # RTR150711PB. See the mentioned help article for placement of the lights and tape.

  • Replacement Trailer tail Light for Bargman 91 Series Lights on a 1995 Palomino Pop Up
  • Yes you can use Optronics light # RVST51 as a replacement for the Bargman 91 series tail lights you have. It looks like a bulb is missing in the picture. The running lights not working could be a symptom of a wiring issue that changing the lights would not solve. If you connect the trailer to the tow vehicle and turn on the running lights, use a circuit tester such as # 3808 to test the wiring at the tail lights. If no power is getting to the light then you know the issue is the wiring....

  • Replacement Taillight Lens Recommendation for Stratos Boat Trailer Passenger Side Tail Light
  • I believe I have a solution for you, but the SAE number you listed isn't a reliable way to get a replacement lens. Based on the picture you submitted (thank you for that by the way), it looks like you are in need of a part # A39RB. This lens measures 7-7/8" L x 3-1/4" W.

  • Are the LEDs of the Optronics Light # STL8RB Attached to the Lens or the Housing
  • The lens of the LED Submersible Trailer Stop, Turn and Tail Light # STL8RB that you referenced is held on with 4 screws around the outside of the housing. The LEDs on the inside of the light are not attached to the lens. They are attached to the housing. Since the light isn't designed for that type of modification it would be hard for me to safely recommend you do that. An easier option might be to install the # 763560 as this is a capsule designed to replace the light assembly of a...

  • Amber Trailer Blinker/Running Light Recommendation for Use on an Older Truck
  • We don't have exactly what you said you need, but the closest thing we have would be the Miro-Flex, Waterproof, Rectangular, LED # STL35AB. This is an LED amber light you could use that has dual intensity so that it can be used for a blinker and running lights. Only thing is that this is much bigger at 5-5/16" L x 3-7/16" W x 2-5/16 D. For a harness to plug into the light you would want # A47PB and then for a grommet part # A33GB.

  • Driving lights on Aftermarket Front Bumper for my 2006 Jeep Wrangler Rubicon
  • The best option and closest match we recommended for a hole with 2-3/4 inch radius is the Optronics halogen light kit # QH-87CD. It measures 2-7/16 inch wide x 2-7/16 inch tall x 2-3/4 inch deep. If you have the Jeep running the alternator will provide the power to the lights and winch. Unfortunately, we don't currently stock LED driving lights that will fit 2-3/4 inch radius fog light holes.

  • Troubleshooting Reverse Lights Not Working on a 1997 Northland Truck Camper, 11-footer
  • First visually inpect the condition of the bulbs and the grounds of the lights that aren't working. If they look good then you could use a jumper wire like you said to test to see if the lights will illuminate. If so, then you know the problem is somewhere in the wiring. It could be that the lights aren't connected, if they have never worked it could be that they were never connected initially.

  • Reflector Recommendations for a Car Park Built of Gabion Baskets
  • Thanks for the pic! That's a pretty cool setup you have. Since there really isn't a great way to attach the reflectors to the mesh I think your best option would be to get 3" Round, Double Face Driveway Marker Reflector w/ 35" Steel Pole # DM35RS and then drive them into the ground where needed. Since you are from Australia I attached a link to our shipping policy page.

  • How Does the Optronics 3-Function Tail Light Provide 3 Functions if There are Only 2 Wires
  • The Round Trailer Tail Light # ST24RB grounds through the mounting studs so the two wires are all that is necessary for activating the stop/tail/turn signals of the light. The bulbs are dual intensity so each wire will control a different intensity of the bulb and then ground through the mounting studs. The stop/turn will be on one wire and the tail light will be on another. To determine if you need more lights at the rear of your vehicle you will need to consult your local laws and...

  • Amber Side Marker Light Recommendation for a Shorelandr Boat Trailer
  • Yes, the Sealed, Mini Rectangular LED Trailer Clearance, Side Marker Light # AL91AB should work very well for your trailer. This light is 2-1/2" L x 1-3/16" W x 7/8" D and is submersible so it should work out perfectly. For a bracket to install the light you will want the # A91BOB, and then for a wiring harness you would want the # A46PB.

  • What is the Diameter of the Mounting Post of the Dual-Face LED Optronics Light # STL53ARPB
  • 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.

  • It doesn't look like we have an exact match for the clearance light on your trailer, but we have several similarly shaped ones that could work. If you measure the dimensions of your light and then check out the link I attached to the right you will see a list of all of the submersible, rectangle clearance lights we offer.

  • Trailer Wiring Kit Recommendation for a 40 Foot Long Pontoon Boat Trailer
  • I have a solution for you, but as you have noticed all of the light kits we carry only come with 25 feet of wire. What you would need to do is get a kit like the part # TL36RK and then order a quantity of 15 feet of the Bonded 4 Wire Sold by the foot part # 16-4B-1 to extend the wiring of the kit.

  • Replacement Tail Lights for a 1977 Shasta 1600 Trailer
  • Based on your picture it looks like the left side is # RVST56 and the right side would be # RVST55. These lights are 8-5/8 inches across, 6-5/16 inches tall, and 2-1/16 inches deep. The housing looks different though so if the lights I mentioned above have different dimensions then your current lights then you would want to replace the bases as well with 2 of # RV50BK. And that should be all you need. Just for reference on the wiring, since you can't always go by wire color: Red...

  • LED Trailer Clearance Light that Uses Red Diodes
  • Some LED trailer lights use colored LED lights and some use white LED lights. It all depends on the light. But for # MCL44RB1, the LEDs would be white behind a red lens. A light such as # MCL19CRB does use red diodes.

  • What Kind of Light Is in the RV Porch/Utility Light # RVPL8C
  • The RV Porch/Utility Light # RVPL8C that you referenced uses a 10 watt halogen bulb that only draws .87 amps at 12 volts. While this light doesn't have an LED in it, it does draw a very small amount of voltage similar to one. We do not have a version of this light with an LED.
