Question:

Hello, my 2010 Smart Fourtwo Cabrio requires a battery disconnect when being pulled Toad does this light kit work? Meaning, Does the power for the lights come from the RV when the Smart Battery Disconnect is engaged?

Yes, the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 will work perfectly on your 2010 Smart fortwo that requires the battery to be disconnected when being flat towed. The power that activates the signal lights on the fortwo will be coming from the RV so the battery being disconnected is not a problem.

Since the battery does need to be disconnected I recommend adding the Roadmaster Automatic Battery Disconnect with Switch # RM-766 to your setup. This will install on the vehicle and allow you to quickly and conveniently disconnect the battery with a simple switch before heading out.

I have also attached an installation video that you can use for reference.
