US Vehicle 7-Way Blade Connector to European 13-Pin Round Trailer Light Converter - Plug and Play Design

Does this convert all of the 7 blade connections to include reverse lights and 12v power?

Does anyone else notice this adapter makes a clicking noise when you apply the brakes or turn signal?

Does this adapter only helps with the light conversion? Does the other pins on the 13-pin adapter work, such as to power the fridge when engine is on?

Does this conversions support LED lights?
