Roadmaster Tow Bar Wiring - RO34FR

  • Diode Kit
  • Splices into Vehicle Wiring
  • Universal
  • Roadmaster

Smart diodes allow a motorhome that is towing a car to use that car's rear lights if the car has variable voltage incandescent lights. Unlike regular wiring diodes, smart diodes activate only the intended circuit - brake lights or tail lights.


Features:

  • Smart diodes allow a motorhome to power a towed car's lights
  • Works with variable voltage incandescent tail lights
  • Requires wiring and wiring supplies (sold separately)
  • Quantity: 2 diodes
  • Made in the USA
  • Limited lifetime warranty


Smart diodes allow a motorhome that is towing a car to use the vehicle's rear lights, provided it uses variable voltage tail lights. Variable voltage tail lights use the same wire to power the brake lights and tail lights. They do this by using a 12-volt signal for brakes and a 9-volt signal for tail lights.


If a regular wiring diode is used with variable voltage tail lights, then the bulb will light up as though the vehicle is braking whenever the tail lights are on. That is, you can't tell the difference between the brake lights and running lights. Smart Diodes correctly modulate the voltage to activate only the intended circuit. The result is vehicle lighting that looks and functions as intended.

Video Transcript for Roadmaster Smart Diodes Review

Rob: Hey, everybody. Rob here at etrailer.com. Today, we're going to be taking a look at the Roadmaster Smart Diodes for incandescent bulbs. Now, there is going to be a kit available for our Smart Diodes or you can get them just by themselves. And whether you get the kit or you just need the diodes, you're going to get two diodes, that way we can hook up our towed vehicle to our motor home, and have all the light functions going through properly. And in order to legally and safely flat tow your vehicle, you need to have the signals going to the back just like when you're towing a trailer.

That way when we're going down the road, if you hit your brakes in your motor home, that signal will come back here and everyone behind you know you're slowing down or changing lanes. We have ours hooked up and you can see that the lights are working in unison, exactly how they should be.The problem comes in with a lot of new vehicles that have what's called variable voltage. So, they're going to run that signal along one wire. So, you only have one power wire and a ground wire, and that one power wire is going to change voltage depending on how bright they want the light bulb to be. Obviously, the brake and the turn signals are going to be brighter, so it's going to send more power to the bulb, opposed to when it's on the taillights where it's only going to send a little bit and the bulb's going to be dimmer.

But our Smart Diodes are going to take care of that. They're going to have all the signals coming into the diode. It's going to modulate the voltage correctly so that it, when it comes out to the bulb, only the intended circuit is going to come on.So, if we have our diodes in place and we have our tail lights on, we're going to get that signal coming in, and it will go out to the car's bulb. But as soon as we hit the brake or we hit our turn signal, that signal's going to come into the diode. It's going to realize that it needs to be a higher voltage and it's going to put the appropriate amount out.

I know a lot of customers are going to be wondering, "Well, how do I know if my car or my vehicle has a variable voltage system or not"Well, you can look into it and check and test your wires, but there's no need to because our Smart Diodes are going to work with variable voltage vehicles that have incandescent bulbs and normal lighting systems, so long as they have variable voltage bulbs. I suggest using these opposed to the traditional style diodes because there's going to be less of them.We're only going to need to have two installed for our entire installation and they're going to take up less space. Another thing I like about the Smart Diodes, it's going to make your installation a little bit easier. We're only going to have to cut one factory wire on each side of the vehicle, opposed to two or maybe three with regular diodes. So, here I've got a couple of normal diodes and you can see if we look at the terminals, we're going to have two in terminals and one out terminal.

Now, it's going to allow us to have our factory wire and signal come in and go out to the bulb, but also a secondary signal coming from the back of our motor home with our tow bar wiring. That way it goes in and it'll go out to the bulb. But again, if we're using regular diodes on a variable voltage vehicle, we're always going to get 12 volts, so that taillight signal is going to be too strong, and it's going to look like our brake lights are on all the time.And again, one diode of these normal ones are only going to be able to handle one function. If we look at our Smart Diode, they're going to be labeled with all the terminals. We're going to be able to get our RV tail light signal in as well as our RV brake light on one diode instead of having to have two of them. But if we look at our diode, it is going to be labeled and we're going to be able to get both of those signals into one. So, it definitely is going to save a lot of space behind the taillight when we go to install it. Roadmaster went ahead and made the housing out of aluminum because that's actually going to be the heatsink. This is going to help reduce the amount of heat and transfer it out so it doesn't get too hot because diodes naturally are going to get a little warm whenever they're getting used.And one thing that I really like about the diodes, regardless of what kind of vehicle you're putting it in, it's only a one-time installation. We're not going to have to worry about putting those magnetic lights up and running a wire to the front of the vehicle or the back of the motor home, and then taking them down, and setting it up each time. We're going to install these one time and then we can simply just get in, hook up the chords, and the rest of our tow bar, everything to go, we're ready to go. But when we want to drive our vehicle, everything's still going to work exactly as it should and there's not going to be any kind of exterior change. The way our Smart Diodes are going to work is when our signals come from our motor home, for example, our left turn signal, when we turn that on, it's going to flow into the diode, and then our Smart Diode is going to figure out whether it's a taillight signal or a turn signal. And then, when it comes out, it's going to illuminate the bulb with the correct signal.And again, if we're having our taillight come down, our signal will come down from the motor home and since it needs to goes to each side, it'll split off, sending a signal to each one of the diodes. And it's going to go through a resistor inside the diode so that it only puts out a certain amount of voltage to each one of the bulbs. Instead of being a bright brake light, it'll be a dimmer tail light.Well, with all that being said, again, I'm Rob here at etrailer.com, and this is going to finish up your look at the Roadmaster Smart Diodes for incandescent bulbs.
