• How Do I Know Which Wire To Connect To The Black Wire On The MCL44AB
  For a clearance light like the # MCL44AB The black wire on the light would be connected to the running light circuit on your trailer. That said, wire colors are not universal. We would go in with a wire probe like the # PTW2993 to determine function.

• How to Install New Trailer Lights that Only Have One Wire
  A trailer light that only has 1 wire means that it grounds through its mounting hardware. The single wire is the power wire. The best surface to ground a light to is steel. If steel is not available in the area the light installs you can attach a ring terminal and wire to the grounding stud and attach the other end of the wire to the original ground wire from the old light.

• Installing LED Clearance Lights With 2 Wires
  Two-wire LED clearance lights such as the Red # MCL32RB or the Amber # MCL44AB have one wire for the power lead and one ground wire. The wire that was attached to your old clearance lights will be spliced to the power wire of your new lights. The black is power and white is ground for these lights. If you take a look at the video I have linked you can see how these lights are installed. I have also attached a couple of links to help articles on trailer wiring which you should find useful.

• Trailer Lights Do Not Light Up But have Power on All Wires
  The problem you are experiencing sounds like a ground issue and/or short circuit. 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. 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 and corrosion free bare metal surfaces. The...

• How Do I Wire A 2 Wire Light In Place Of A Single Wire Light On My Camper?
  The lighting on your 1987 camper van used a single power wire input and would ground the lamp through the lights mounting bracket. This is how the Optronics LED Trailer Clearance and Side Marker Light # MCL44AB1 would connect. The Optronics LED Trailer Clearance and Side Marker Light # MCL44AB uses a 2 wire connection similar to the wiring on your new lights. You will attach the red power input wire on your new lights to the red wire on your camper van. The white wire will need to be...

• How To Replace a Trailer Clearance Light With One Wire Using a Light With Two Wires
  If you are replacing a trailer marker/clearance light that only has one wire with a trailer marker/clearance light that has two wires like the part # MCL44AB that means the previous light grounded though the mounting hardware and the new light grounds with a single ground wire. Therefore, the ground wire will just need to be run and attached to the trailer frame. That said, I don't know which color has which function on your light so you will just need to test these for yourself if the...

• Replacement for GloBrige 118A/117R Amber LED Clearance Light on a 2014 Big Sky Montana
  To replace the right clearance light on your 2014 Big Sky Montana I recommend going with the Amber Optronics # MCL44AB. This isn't a "direct" replacement as this is a 2 wire design, but we actually have a customer review on this product page saying that it is a perfect replacement for the GloBrite 118A/117R LED light that you referenced. I am not sure why your clearance light has 3 wires because a clearance light just carries 1 function. This means that you just need 2 wires; 1 for the...

• Recommended Replacement Lights For A 2014 Gulf Breeze Ultra Lite 22 TRB With Hail Damage
  It doesn't look like we currently offer the correct lens replacements based on the dimensions you provided and the tail light you have looks like the base would be too broken and would allow water in to replace just the lens so you're looking at a complete replacement for these lights. For the tail lights I recommend the Low Profile LED RV Tail Light w/ License Bracket - Driver's Side # RVSTLB61 and Passenger's Side # RVSTLB60. The clearance lights can be replaced with the Optronics...

• Replacement LED Marker Lights for a 2009 Timberlodge Camper
  Thanks for providing the picture. It looks like your current marker light is around 3 3/4" long and 1 1/2"- 2" wide and has mounting holes 3" apart. While we don't have anything in those exact dimensions, we do have several that are slightly larger so when you replace yours you will be able to completely cover the space the old lights used to be. I am slightly concerned about the width of your current light and how it fits in the groves on the side of your camper. I am going to recommend...

• Using A Marker Light With Two Wires To Replace Old Light That Only Had One Wire
  Since your old trailer light only utilized one wire that means the one wire was used for power and the old light got it's ground through the mounting hardware. Since the new light like # MCL44AB has two wires, one for power and one for ground, you'll just need to connect the black wire for power to your trailer, and then run the white wire to your frame and ground it.

• How to Install Trailer Light part # MC32AB to a Trailer with a Single Power Wire
  Sounds like you bought the # MC32AB and the # MC32RB to replace what you have on your trailer. This is the only style of light we offer in that size. It sounds like your trailer may ground it's light assemblies through the mounting hardware. Which in this case would mean that you would only need to run the ground wire of this light to the mounting hardware and the other to the power wire of your trailer's wiring.

• Replacement for Glo-Brite 118A Trailer Light
  From what I can find the 118A light is an amber light that measures 4 inches long by 1-1/2 inches wide. The light we have with these specs is part # MCL44AB but it's only a 2 wire light. We don't carry Glo-Brite products so I don't have any specific contact numbers to relay for you, but this light should work just fine.

• How to Install a Trailer Clearance Light with Different Color Wires
  There are typically only two wires on a clearance light which are for ground and power. There is not a standard wire color to function chart on a trailer for anyone to abide by so it will be best to test them for function with a circuit tester. In order to check this all you need to do is start the vehicle, plug the trailer connector in, and test which of the two wires has power. The light should then specify which wire is for which function but you will again need to test the trailer wiring...

• Troubleshooting Trailer Lamps That Receive Power But Won't Illuminate
  If you're showing power on the black wire feeding the lamp, and the bulbs are known to be good, the only thing that could cause the lamp not to illuminate is a poor ground connection. You can test this theory by getting a long length of wire and attaching one end to the negative battery terminal of the tow vehicle and touching the other end to the ground wire of the lamp while the running lights are turned on. If the lamp lights, you've confirmed that there's an interruption in the ground...

• Installing Side Marker Lights on Trailer
  The white wire with the ring terminal attached to the LED Trailer Clearance, Side Marker Light # MCL44AB needs to be grounded to your trailer's frame. It is typically a good idea to run all of the light grounds back to the main trailer ground. The black wire on the light will be spliced into the trailer's running light circuit. Traditionally, the brown wire on your trailer is the circuit the black wire will be spliced into, but using a circuit tester, like # PTW2993, is helpful to ensure...
