Propane tank Changeover Indicator

[cmerkert]

I have seen a post about a simple sensor light that goes on when you propane tanks switches over from the primary tank to the secondary. (See link ) This is great to let us know we are on tank 2 and not have to open the nose cone on a Cougar. The only thing is it looks like it goes over a different type of propane regulator. Does anyone know what regulator is on the Courgar XLites. Mine is a '14 XLite and in storage and wrapped up. Just doing some pre-planning getting ready for the season.

1. What type is the Courgar XLites regulator?
2. Does anyone know off the cuff of the propane switch indicator that would work on it?

Thanks. Let the Mods of 2018 begin!
