Do I Need The Roadmaster Stop Light Switch To Install The InvisiBrake On A 2021 Wrangler Unlimited  


Im looking to install the Roadmaster InvisiBrake system on my new 2021 Wrangler Unlimited and saw that you have the RM-751490 stop light switch thing listed as being required. What does this do and is it really needed?


Expert Reply:

The Roadmaster Stop Light Switch Kit # RM-751490 is indeed required when installing the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 on your 2021 Jeep Wrangler Unlimited. This is due to the brake light switch shutting off after 10 minutes of inactivity and while being flat towed. The # RM-751490 will keep this from happening and will get the # RM-8700 working properly.
