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.

Video Transcript for Roadmaster Tow Bar Wiring RM-732 Review

Today we're going to be taking a look at the Roadmaster Brite-Lite wiring converter. The Brite-Lite converts a three wire electrical system on a towing vehicle to a two wire system on the towed vehicle. This unit allows the towed vehicle's lights to work in tandem with the towing vehicle's lights. The unit's going to help increase overall safety on the road. Testing does show that the Brite-Lite makes turn signals and brake lights brighter than other brands. The unit is very reliable.

It's going to feature an anodized aluminum heat sink to effectively dissipate heat, and it's going to use 16 gauge wiring for all the wires on the unit. Now this unit gets mounted on the towing vehicle by using the adhesive backing that's included. The right turn, left turn, and brake light wires on the towing vehicle needs to get connected to the input wires on the converter with butt connectors. Then you'll need to use a ring terminal to connect the ground wire from the converter to a clean metal surface on the towing vehicle. Now the white wire is going to be your ground wire, red wire is your brake wire, the yellow wire is for left turn, and the green wire is for right turn so you want to get these connected again to the wires of the towing vehicle using butt connectors. All the necessary connectors that are needed for your installation are not included, so those will need to be provided separately if you don't already have those. The two wires come out of the other side of the converter. These are going to get spliced into the wiring on the towing vehicle's wiring harness like a four-way flat or a seven-way connector. The yellow is left stop and turn, the green wire is right stop and turn, so once you have those spliced into the wiring harness like your four-way flat or seven-way, when you connect that to the harness on the towed vehicle everything's going to be working properly, the signal's going to be sent through that harness.

Again, this is designed to convert a three wire electrical system on your towing vehicle to the two wire system on the towed vehicle just to insure that the towed vehicle's lights work in tandem with the towing vehicle's lights. Measurements real quick of the actual converter. Going this direction that's going to give us a dimension of three inches. Going this direction it's going to measure about three and one quarter of an inch, and in the depth of the unit from front to back or the thickness is only going to measure about seven eighths of an inch thick. That's going to do it for today's look at the Roadmaster Brite-Lite wiring converter.

The product was used on a sports car that was made with a separate turn light bulb then changed to a tail lights with one bulb for everything. This converter did the job so I now have tail, stop and turn lights on a duel filament bulb. Just installed it so do not know how long it will work. Delivery was on time. Tried one other brand prior to this which did not work. The packaging gives a phone number if there are any problems which good. 549846

I bought this product to connect my lights on my horse trailer to my 95 peterbilt. Wiring was a snap and within 20 minutes all my problems were solved! I highly recommend this product and HIGHLY HIGHLY RECOMMEND buying from etrailer.com!! I went to 3 local trailer dealers ( 2 of them are nationwide brand name manufacturers) and all of them had no clue to convert 3 wire light systems to a two wire. Within 5 minutes of looking on etrailer.com i ordered what I needed and it's history as they say!!! 206744

Product arrive reasonably fast. I installed it the same night it arrived and took me about 2 hours total (I like to work slow). So a bit of the back story: I am customizing a 1992 Softail Custom. I basically chopped both fenders and deleted the center tail light. After some rewiring, I adapted the turn signals to run as tail lights as well. Nothing fancy, I simply ran an additional wire, socket and 140 size bulb to the turn signal assembly, seems crude but hey... it works, and the light housing is big enough to accommodate both bulbs. So now I had tail lights and turn signals but..... no brake lights. The dilemma was that my brake light was wired to the center tail light which I deleted (It used a dual-filament bulb). Therefore, in order to make the turn signals work as brake lights as well I used the RM-732 to pull the brake light signal into the same bulb as the turn signals. The wiring is straight forward and the unit fits neatly on top of the battery under the seat. It's almost like they designed it for this bike. I'm very pleased with this purchase and I feel safer riding my bike now that my brake lights actually come on when I apply the brakes. Thank you e-trailer! 596612

For those of you that pull trailers with electric brakes behind both pick-ups and semi tractors this the converter that you will need to make the brake lights work when you are pulling with a semi. If the semi tractor needs to pull a mix of trailers you want to leave it with the 7 pin round and if the trailers with the 7 flat RV style plug needs to be used when a pick-up pulls it. With this converter and one each of the opposite plugs, you can build a adapter to use to get your brake lights working when pulling the lighter duty electric brake trailers with your semi tractor. Reasonably priced and high quality. 496923

  • Recommended Wiring Converter for Separated to Combined Circuits and Combined to Separate
    It sounds like you need to combine separate brake and turn signals to a single wire on each side. If that is the case, you will use Roadmaster Brite-Lite Wiring Converter # RM-732. If they are combined and you need the separate functions, then use # 118158 or # C56196.

  • Recommended Light Converter to Isolate Turn Signals From Stop Light For Trailer
    The Roadmaster Brite-Lite Wiring Converter # RM-732 is not the correct converter for your application. You instead want the Curt Vehicle to Vehicle Tail Light Converter # C56196. You will not use this on the vehicle side, but will tap into your trailer wiring to separate the turn signal from the stop light. By isolating those signals you can get the separate feature. Then you will need a two wire LED so you can have the running light on one wire and the turn signal on the other. The...

  • 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 # 40376 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...

    A 7 pin flat connector is normally European. It will give you the same functions as a 4-way flat. To convert the wiring to make it functional with a 4 way, you will need the Roadmaster Brite-Lite Wiring Converter # RM-732. You can use a circuit tester like # PTW2993 to determine functions for proper connection.

  • How to Make Adapter to Go From 7-Way of Semi Truck to 4-Way
    The problem with semi truck 7-ways is that they have the turn signals separated from the stoplights so you end up with needing a converter installed on the adapter too so that the signal matches the trailer lighting. If this is the case you can build an adapter using the part # RM-732 as a signal converter. You will need a round pin male connector, # PK11702 and then the part # W787264 for a 4-way. Basically you will be splicing the converter between these two to create the adapter. The...

  • How to Use the Roadmaster Brite-Lite Wiring Converter with LED Lights
    I am not quite sure I understand what you mean. A relay does not regulate voltage, that is what a resistor is for. A resistor is more often than not required when using LED lights as the lower current draw can trick the system into thinking there is a short which will then send a pulse to the lights causing hyper flash. If you are in fact referring to the relays then I would not have a wiring diagram for this as each are different and will need to be wired according to the pin out which...

    The Brite-Lite converter # RM-732 can be used with your 2018 Jeep Wrangler and kit # RM-154. But I want to clarify what this converter does. It takes separate brake light and turn signal circuits and combines them. Those circuits are already combined on a 2018 Jeep Wrangler and if the RM-154 is plugged into a trailer connector on the RV side then those circuits are also already combined. If the RV does not have a trailer connector but has turn signals and brake lights that use separate...

    I do have an option for you but there isn't any sort of adapter that will go from a Euro 13 Pin to a US 7 Blade. Therefore, in order to tow trailers with US 7 blade or 4 pin connectors you will need to convert the trailer wiring harness on the vehicle from EURO to US spec.

  • Troubleshooting Trailer Turn Signal Lights Not Working with 2014 Peterbilt 579
    The 7-Way connector on your 2014 Peterbilt Semi will feature separate circuits for its brake and turn signal lights, while a standard trailer wiring setup will have these circuits combined. This is likely why the turn signals aren't behaving correctly and you aren't getting appropriate power at the connector. All you should need to do to resolve this issue is add a converter like the Roadmaster # RM-732 before the 7-Way on the truck. This will combine the turn and brake light circuits...
