• How Does the Optronics Trailer Light # STL79RB Wire to Trailer Wiring
  The wiring of the Optronics Trailer Light # STL79RB that you listed are: The white wire, with the mounting eye, is a ground wire that needs to be connected to the white wire of your trailer wiring. The black wire would be connected to your running lights and is the lower intensity illumination. This should be run to the brown wire of your trailer wiring as this is usually the tail light circuit. The red will be wired to the brake/turn wire and is for the higher intensity illumination....

• Which Wires Should be Tapped Into When Adding Additional LED Marker Lights on a Boat Trailer
  In order to add LED lights that shine on your boat at night, they will need to be wired into the running light wire or wires on the trailer. On a typical 4-Way flat, it is the brown wire coming from the trailer side connector. To be certain, you can use a circuit tester like # PTW2993. With the trailer connector and vehicle lights on, probe the wires coming from the back of the connector until you find the one that is hot all the time. You can trace this wire back to where you want to...

• Troubleshooting Tail Light Issues on New Grand Design Trailer
  Since you tested the tow vehicle's connector and know it's working properly, we can at least focus all our attention on the trailer side. It sounds like you've already done this, but it certainly sounds like there's some kind of ground issue on the Grand Design that's causing the dim lights, and now the issue on the left side tail light. Check once more to make sure all your ground connections, both the main harness ground for the 7-Way and each individual ground for the light assemblies...

• Recommended Lights to Increase Visibility on Hitch-Mounted Bike Rack
  The Optronics Sealed, Streamline LED Trailer Light # STL79RB referenced in your question will work to provide an additional light on your bike rack, however there may be easier options. You might have trouble mounting the light assembly to the rack itself and the 3-wire design will not allow for easy disconnect when you are not using the bike rack. For an easier option, I recommend looking at the LED Light Kit # 98174LED. You can easily mount these to your bike by using the Mounting Bracket...

• Adding a Third Brake Light to a Small Camper Trailer
  You could use light # STL79RB as a third brake light. Normally it is not recommended to mix LED lights at incandescent lights because the lights don't have voltage/amperage regulators and an incandescent light could draw too much power through an LED and burn it out. But it would work fine in this case because in order to have a third brake light you would have to separate out the combined turn signal/brake light circuits to get a dedicated brake light only function for a third brake...

• Replacement Tail Lights For a 2021 Lance 2185 Travel Trailer
  The Optronics Streamline LED Trailer Tail Light # STL79RB is going to be the closest light we have to what was put on by Lance for your 2185 travel trailer. This light is 17" long, 1-3/8" wide and 1" tall. The mounting holes are spread 16-1/8" on center and like yours the wiring is offset. It is 8" from the top and 9" from the bottom to the wiring center. As the lights are going to be different heights I recommend replacing both of them so they match and use Clear Silicone # FAS59FR to...

• What Wiring Would be Needed to Install a Third Brake Light Mounted to a Boat Outboard Motor
  To add a third brake light to a trailer is pretty simple, but does require an adapter to convert the signal. Because trailer tail light systems combine the stop lamp and turn signals for each side onto a single circuit, you will need to use a vehicle-to-vehicle tail light converter, part # 118158 like you mentioned to split the brake light circuit back out. Looking at the diagram I produced for you will give you a good idea of the wiring layout. Now the temporary mount for the light...

• Recommended Wiring and Lights for Utility Trailer
  I'm assuming you want to replace everything here so I will start off with a 4-way. I recommend using the Hopkins Endurance 4-Way Flat Trailer Wiring Harness - 30' Long # HM48265. This will give you a lot of wire to work with so you can hook up all of your lights. This uses your typical 18 gauge wire for the lights and 16 gauge for the ground. If you need additional wire you can use the # SWC97FR or # DW02923-1. You could use the Self-Stripping Connector with Waterproof Sealant - 14-18...

• Using Vehicle To Vehicle Taillight Converter # 118158 to Provide 3rd Brake Lamp on Trailer
  The Tow Ready # 11858 is essentially a reverse tail light converter. A trailer used what we call a combined tail light system, where the signals for the brake lamps as well as the turn signals are carried on the same circuit. The # 118158 reverses this process, by separating the brake lamp signal from the turn signal circuit. To install a 3rd brake lamp on a trailer, the # 118158 is exactly what you would need. You would tap the green and yellow wires on the INPUT side of the converter...

• LED Strip Recommendation for a Trailer for Additional Stop/Turn/Tail Function Visibility
  If your LED strips only have a power and ground wire then they only have one illumination intensity and would not work for what you are trying to do. I would un-install them and go back to the wiring setup you had previous for now. Your best option would be to get the 3-Function LED Bar part # STL79RB that you referenced as this is specifically designed for what you are trying to do. I would run one on either side of your trailer. Connect the white wire to ground, the red wire will connect...

• Can a Horse Trailer be Converted to Run Off 12 Volt DC Power and 110 Volt AC Power
  The biggest hurdle to overcome is having the trailer lights run off of 12 volt DC and 110 AC power. On a trailer that was not set up for this from the factory that means you would have to have a transfer switch installed and the associated wiring and electrical devices for it to be functional. In a nutshell retrofitting a trailer with a transfer switch is a task best left to professionals who work on trailers and RVs. The easy way to get AC power on the trailer is to use a power inverter...

• How Can I Wire Center High Mounted Stop Light On Truck Camper To R/L Turn Signals
  I was unable to find any definite information about the requirements of a CHMSL on a camper such as you are describing. To have the best information as to the requirements of the areas where you are traveling, I recommend calling the DOTs of the areas where you will be traveling to be familiar with their state and local laws regarding CHMSLs on a camper. To connect a CHMSL to the left and right turn signals, you will want to use a converter, like part # 118158. With this converter, you...

• Are All LED's of the Optronics Stop, Turn and Taillight # STL79RB The Same Brightness
  According to my Optronics representative, the # STL79RB is purposely designed so that the middle three diodes which illuminate the running light function are a bit more dim. The outer diodes are brighter, and the lens tends to magnify the diodes making them appear much brighter.

• Installation Instructions for Optronics 3 Function Streamline LED Light part # STL79RB
  The white wire, with the mounting eye, is a ground wire that needs to be connected to a metal surface on the trailer that is electrically grounded like the frame. The other two wires will provide the brake/turn and running lights. This light will not provide functions for both sides of the trailer, in order to do that, you would need two units. The black wire would be connected to your running lights, and the red will be wired to the brake/turn wire. In order for this light to simultaneously...
