Hi, removed the fuses and the light goes off, what was the 8v reading turns into a 12v reading on pin 87 of the relay when I do so. The 8v is the constant feed to the light even when the truck is off and the key is out of the ignition, which is my problem. Can this be a short or a bad ground...

Bit of an update. After taking things apart and the relay out for the headlights the light still stays on. Leading to believe I have a short somewhere
