Electric Brake System

Check the trailer brake lights by having someone operate the brake and turn signals on the tow vehicle while you visually verify it is functioning.  If your trailer has electric brakes, your tow vehicle will have an electric brake controller that is required to be installed at the driver’s position that sends power to the brakes. To check the condition of the electrical brake system, pull the breakaway pin and check for the illumination of the green LED indicator light. When fully lit, the battery is charged and the system wiring is correct.  To test this system, operate the brake controller while trying to pull the trailer at a speed of less than 5mph to verify they are operating and you can feel them engage.
