Roadmaster Tow Bar Braking Systems - RM-751472

  • Stop Light Switch
  • Roadmaster

Avoid damage to your towed car by ensuring that your supplemental braking system is properly positioned and working effectively. Kit activates your RV monitoring system to alert you when the brakes of your towed car are being applied.


  • Activates motorhome brake-monitoring system whenever brake pedal in towed car is applied
    • Ensures that the supplemental braking system is functioning properly
  • Works great for any application that does not have a tow position in the ignition
  • Wires directly into towed car's fuse box for constant current
  • Made in the USA


  • 12 Volts
  • Application: custom-fit for your vehicle

This kit allows your RV's monitoring system to alert you whenever the brake pedal of your towed car is being applied. Other systems operate according to whether the air cylinder is extended and provide no indication of what is happening with the pedal itself. If your supplemental braking system is improperly installed, it may be continuously pressing on the pedal, impeding it from fully retracting and possibly causing damage to your vehicle's tires and braking system. With Roadmaster's Stop Light Switch Kit, you will always know when the brake is being depressed, and you will avoid costly damage.

Works well.


Great system. Easy to install.


Received this kit yesterday and installed it today. One of the easiest installs I’ve done lately. Parts all fit fine and instructions were clear and easy to follow.


works fine and easy to install, just a little adjusting needed


I have ordered many products from etrailer and their customer service is 12 on a scale of 1 to 10. I ordered my products on the weekend and they were delivered on a Wed. I also later found cheaper prices on a few of the items and submitted the info for the 110% lower price guarantee and received the refund within a few hours. These folks are just plain great!


Instructions were very good, pictures showed what to look for. Had to pad it out a little, to have room for adjustments. Easy install.


Great product with instructions. Works great...

    The Roadmaster Stop Light Switch Kit part # RM-751472 is a fit for your 2018 Chevy Colorado. I attached a link below to the install instructions that detail exactly how it installs.

  • Can the Even Brake Supplemental Braking System be Used on a 2015 GMC Canyon
    Yes, you can use the Even Brake supplemental braking system # RM-9400 with your 2015 GMC Canyon. To make sure the braking system is properly positioned and working effectively we also recommend the stoplight switch kit # RM-751472. It will activate the RV monitoring system to alert you when the brakes of your towed car are being applied. Without it you would not know if the brake pedal in the Canyon is actually moving or not.

  • How to Power Supplemental Braking System on GMC Canyon After Disconnecting Battery
    Since GM requires that the battery on your Canyon be disconnected for flat towing, you will just need to add the 12V Outlet Kit # RM-9332 to your setup to provide power to your Roadmaster Portable Braking System # RM-9400. This will wire directly to the battery to supply the necessary power for this system, which won't be affected by using the Automatic Battery Disconnect # RM-766 that you also mentioned. Please also note that you will need the Stop Light Switch Kit # RM-751472 as well...

    I took a look at the owner's manual of a 2016 Chevy Colorado and a four wheel drive model can be towed so long as it has a N (neutral) and Four-Wheel Drive Low setting. If you look on page 331 of the manual it will go over the detailed process on the ncessary steps to flat tow. There was no mention on how long it can be towed before the eninge needed to be restarted; the only requirement was that you do need to disconnect the vehicle battery in order to flat tow.

  • Is it Possible to Tow a 2WD 2016 GMC Canyon?
    The owner's manual of your 2016 GMC Canyon specifies that the two-wheel drive version of this vehicle cannot be flat-towed, and the only way to tow it at all would be to use a tow dolly and have it mounted by the rear wheels. However, the tow dolly's we carry state not to tow vehicles by their rear wheels.
