Good day, I would like to know how to change the polarity of the sockets of the car since I want to install some led bulbs, but the polarities are reversed, the command that makes the change of lights sends mass signals, and the normal bulbs do the changes with current and have a fixed mass, can anyone tell me how the connection would be? The car is a Chevrolet Sprint

Andrew What you should notice is the polarity that reaches the socket. Not if the positive or negative is interrupted. To change the polarity of the socket you must reverse the cables that reach it.

Depending on the power to be controlled, you could use a transistor to reverse the polarity, you can also feed the socket with constant positive, instead of massa constant
