Guys, I have just installed a new trailer light converter from hopkins after my original s*** the bed. Install when smooth. However I noticed while testing functionality at night that my whole rig dims some when the I plug in my boat trailer. This would represent a normal night driving situation. The trailer has 6 small marker lights and 3 tiny marker lights. None of the lights are led. In a similar situation if I plug in my small utility trailer with 2 led lights, the vehicle lights dim ever so slightly. I have never noticed this happening before. Is this normal? If not what is the possible cause? Could my alternator be producing too low voltage at idle? Any help is always appreciated
