Roadmaster Brite-Lite Wiring Converter

The Brite-Lite converts a 3 wire electrical system on a towing vehicle to a 2-wire system on the towed vehicle. Three wire systems use a separate wire to carry the brake signal. Two wire systems have the brake and turn signals sent along the same wire. Lab tests have shown Brite-Lite makes turn signals 65% brighter and brake lights 25% brighter than other brands. Brite-Lite can help prevent rear-end collisions in heavy traffic or under adverse conditions. Heavy-duty aluminum heat sink design effectively dissipates heat and outlasts other brands.

My project was converting my 1972 Camaro rear two light system to a three light system from a 1978 Camaro donor wiring system. The original 1972 wiring was missing. Laura was the tech that helped me. She was very knowledgable and patient with me. The RM732 converter was very easy to install and did exactly what in needed for this project. Thanks Kelley Bowin 69858

  • Converting Separate Turn Signals and Brake Lights to Combined Turn and Brake Lights on a Trailer
  • If the trailer is one that is pulled by a motorcycle or a trailer designed to carry a motorcycle, you will need a converter in order to convert the wiring system used by the 6-Way to a 2 wire system used by trailer lights. The converter you can use is # RM-732. This takes the separate turn and brake signals and makes them a combined circuit. When you hit the brakes with the turn signal on, it should blink on one side and the other side will remain a solid brake light. The converter will...

  • Is Optronics Sealed Streamline LED Trailer Tail Light Designed to be used with a 4-Wire System
  • The Optronics Streamline LED Trailer Light is designed to be used with a 3 wire system, not a 4 wire. It has 3 wire leads, one for ground, one for tail light and one for a combined brake/turn signal. You can use this, you will just need a converter to bring the system down from a 4 wire to a 3 wire. If this is for a trailer behind your 1988 Toyota pickup, you can use a trailer harness with a built in converter like part # 119179KIT. If this is for some other sort of project you could...

  • Is there a European 7-Way to US 4-Way Trailer Wiring Adapter for a BMW
  • Bascially, there is no easy way to convert the European 7-Way to a US 4-Way. We do not carry any kind of adapter that you could use. You are left with 2 options. First, you would install a separate wiring harness which would be the easiest. Or, you could attempt to fabricate an adapter. You would need to use a converter, # RM-732. The red wire on the input side would attach to the brake light wire on the vehicle wiring. The white wire grounds to the frame. The yellow wire will attach...

  • 2 Wire to 3 Wire Tow Vehicle Taillight Adapter for 2006 Chevrolet Colorado
  • If your Colorado has separate turn signals and brake lights then you will need to use a Vehicle to Vehicle Tail Light Converter, item # 118158 or item # RM-732. We have a video that explains how to install the converter (see link). If your vehicles taillights and turn signals are in the same bulb then you will not need the Vehicle to Vehicle Tail Light Converter with the item # 48955 Tail Light Isolating Diodes.

  • What is the Correct Diode Kit to Flat Tow a 2007 GMC Sierra 1500 New Body Style
  • I show that for a 2007 GMC Sierra 1500 new body style, you will need to use the Roadmaster 4-diode kit, # RM-154. Your truck has a 2 wire system (combined brake and turn circuit) so additional diodes are not needed. There are diagrams on the product page, below the description, for wiring the diodes, and I have also included the pictures here. If the towing vehicle has a combined brake and turn circuit, you will use the first diagram. If the towing vehicle has separate brake and turn...

  • Tail Light Isolating Diode System # 38955 Install on 2011 Ford Fiesta
  • If you go to the product description page for the Hopkins Tail Light Isolating Diode System, part # 38955 and scroll down to the bottom of the page (use the provided link) you will see 4 install diagrams. The wiring method used will depend on the way the tail light circuits on your RV are wired. The lights can be wired in one of two different ways. If your RV uses what we call a combined system, the brake light and turn signals are combined into a single circuit, using a singe bulb on...

  • Using a 2-Wire Trailer Tail Light on a Trailer with Separate Brake and Turn Signals
  • Since you have indicated that you do have separate turn signal and brake light wires on your Scamp trailer, connecting both of those separate wires to the same circuit on the light # STL90RB is probably what is causing all of the problems including back feeding to the truck. What you will need to do is use a special converter on the trailer side, # RM-732. The separate brake and turn signals will go to the input side of this converter which will then combine them for the output side....

  • Tow Bar Wiring to Flat Tow a 1996 Geo Tracker Behind a Motor Home
  • You can use a diode kit like # 38955 on your 1996 Geo Tracker but there are several things to consider. First, it looks like your Tracker has turn signals that are separate from the brake and running lights. If this is so then by using a 4 diode kit, all the functions will use the brake/running light bulb and the vehicle turn signals will not be used at all. If the towing vehicle (RV) has separate bulbs as well and no trailer connector, you would either need to use a tail light converter,...

  • Trailer Turn Signals Do Not Flash with LEDs on Both Tail Lghts
  • From what I understand, if you have just the turn signals in LED form they work fine. But when you have LED tail lights and turn signals on each side the turn signals do not blink. If you are using light # 42-86-101 that you referenced, we need to make sure that it is wired up correctly. The white wire is the ground and needs to be attached to a clean and corrosion free bare metal surface. The black wire is actually going to be the brake light and turn signal circuit. And the green wire...

  • Combining Brake Lights and Turn Signals to Tow a Trailer with a Honda Gold Wing
  • What are the functions of the wiring harness on the Gold Wing? Use a circuit tester like # 3808 if needed to test its functions to determine what each one does. You should have a ground and running lights for sure. But it is the turn signal and brake signals we are concerned with. What you could do is use a converter, # RM-732. It will take the separate turn signals and brake lights, combine them, and on the output side the signals will be combined to work with the trailer. If you...

  • Wiring a Camper with Combined Brake and Turn Signals to a 2003 Chevy Silverado
  • Trailers and campers typically have what is called a 2 wire system: the brake lights and turn signals on each side are combined. Even though many vehicles have turn signals that are separate from the brake lights, the tow package wiring on the vehicles is already converted. If you are trying to tap into the vehicle wires and not a trailer connector then that would be what the problem is. You would need to use a converter, # RM-732, to take the separate turn signals from the truck and...

  • Parts Needed to Wire a 2001 Saturn SL1 with Diodes to be Flat Towed Behind a Motor Home
  • The 2001 Saturn SL1 uses turn signals that are separate from the brake lights. There are to ways you can wire the vehicle. First, you can wire it so that when connected to the motor home, the turn signals and brake lights will be combined. Or, you can wire it to retain the separate functions. The second method requires a few more parts. For either method, you will start with Roadmaster Universal Hy-Power Diode Wiring Kit, # RM-154. A wiring diagram is included after the description on...

  • Wiring my 1997 Jeep Wrangler lights to work off my motorhome wiring
  • Your Jeep does not have turn signal lights separate from the brake lights so you will not need the RM-732, Roadmaster Brite-Lite Wiring Converter. Your RV already has the 4 and 7 pole connectors wired so the RV already has a converter if it was needed to install the trailer wiring so your wiring to the Jeep should be very straight forward. I have posted a link to our wiring page and to our tow-bar electrical page for you. You may want to consider a Roadmaster 7-Wire to 4-Wire Flexo-Coil...

  • We actually have some helpful diagrams on the product page for the Tail Light Isolating Diode System, # 38955, as well as some videos and an FAQ article that I have linked for you. All of these items should be a big help. When checking the wires on the vehicle to determine function, you will need a circuit tester like # 3808. You will probe the wires behind each tail light to find the turn signal, running light, and brake light wires. You will then wire them into the diodes according...

  • Wiring Roadmaster Diode Kit # RM-154 on a 1983 Jeep CJ-7
  • What you have on your 1983 Jeep CJ-7 is a combined, 2-wire system. The brake, turn, and tail lights may all use the same bulb but they are on separate circuits. This means that if you use a circuit tester like # 3808 if needed and test the wires to the tail light you will find the following: one wire that carries stop and turn and one wire that carries tail light functions. I have included a link to a video that might help showing a typical diode kit installation. Please note that the...

  • Trailer Brake Lights Do Not Work Using 7-Pole Round to 7-Pole RV Adapter on a Freightliner FL70
  • Big rig types of trucks such as your Freightliner use a different type of 7-Way connector than what is used in the recreational market. The recreational market has brake lights and turn signals combined on the same circuit, one for each side. A commercial truck uses separate circuits for turn signals and brake lights. Basically you will need to convert either the truck or the trailer. Converting the truck is easier especially if you are not going to be towing any big rig trailers. If...

  • Winnebago with Seperate Taillights Towing a Jeep and Troubleshooting Brake Lights not Working
  • Since you have connected your Winnebago to both your Jeep and boat trailer and are experiencing the same issue it is likely related to the vehicle wiring on your Winnebago that is the issue. The first thing that I would check would be the vehicle connection 6-way on your Winnebago and make sure that all the wiring to the connection points are in-tact and that the pins do not show any signs of corrosion or damage. You will want to use a circuit tester like the Quickee # 3808 to test...

  • Trailer Wiring Harness Recommendation for a 2004 Pontiac Montana
  • Actually, all you will need to do is install a wiring harness, # 118355, on your 2004 Pontiac Montana. But if you wanted to use those factory wires, because you have separate wires for turn signals and brake lights, you would first need to install a converter. The converter, # RM-732, takes the separate signals and combines them which is what a trailer uses. To wire it up your yellow wire will go to the yellow wire on the converter, green will go to green, white will go to white, and...

  • Wiring a New Truck Bed with 2-Wire Wiring to a 2004 Dodge with Separate Brake/Turn Signal Wiring
  • You will need a converter to make the separate brake and turn signals and brake lights work with the combined turn signals and brake lights on your new truck bed. You could use the Roadmaster Brite-Lite Wiring Converter, item # RM-732, which is designed for 3 wire motor homes down to 2 wire towed vehicles. I would use the Upgraded Circuit Protected Taillight Converter with 4 Pole End, item # 119178, and cut the 4-Way connector off of one end. This will be a more economical solution with...

  • Troubleshooting Non-Functioning For Tow Lights on a 2007 Honda CR-V Behind a Motor Home
  • Without seeing how everything is wired, it is a bit hard to diagnose, but I am guessing you have 1 too many wires run to the Brite-Lite Converter. The ground that is on part # RM-732 should be grounded to the motor home frame or structure. The GND wire that was on the motor home needs to be connected to the ground wire on the CR-V tow light wiring. The CR-V needs an electrical ground, since it is not running and creating a ground it needs to have a ground wire run to the motorhome....

  • How to Wire Up Motorcycle with Separate Wiring to Tow a Trailer with Combined Wiring
  • The issue is that you have separate tail lights on your motorcycle and combined wiring on your trailer. Separate means your brake lights are on separate bulbs as your turn signals. In order to get them to work together you are going to need to use a tail light converter to install a 4-way on your motorcycle. For that you will want the Roadmaster Brite-Lite Converter # RM-732 and 4-way like part # 18002. First you will need to cut off the 5-way on your motorcycle. Next, you will need...

  • No Power on the Output Side of Roadmaster Brite-Lite Tail Light Converter on a Dump Truck
  • On the Brite-Lite converter # RM-732 make sure that the white ground wire is attached to a clean metal surface on the vehicle frame (or trailer frame if mounted on a trailer). The problem you are having could be due to an insufficient ground. Another possibility is that the lights on the output side are drawing more power than the converter can handle. The output side should really only be used for one combined brake/turn signal per side. If there are more lights or a short that could...
