Okay, so, when my lights are off my brake lights taillights and turn singles work but when I go and turn my lights on at night, I don't have any power in the back. I don’t know where to start. Could anyone help me?

Hi,

I need you to check something. Using a voltmeter or multimeter, with the headlamp off, confirm there is 12v. Then check it with the headlamps on and see if it still shows voltage.

I attached the wiring schematic for the exterior lights (minus the headlamps) below for your reference.

Do this and let me know what you find.
