For use when you're driving your HUMVEE or any military vehicle and need to tow a civilian trailer with a 7-way Connector.  You can also buy our adapter allowing you to connect to a civilian trailer with a 4-way or 5-way connector.  The power coming to your trailer will still be 24V.  Simply change out your light bulbs to 24V bulbs available . (24V LED Bulbs will also work with your 12V civilian vehicle)
