Ground?

Are you running LEDs in your exterior lights? If so I would try switching back to standard incandescent bulbs and see if the issue goes away.

We’re would the ground be located for this?

I’ll check the bulbs thing and see but I feel it’s other than that because I’ve run leds for some time now a few years and no problems till recently so.

but it’s weird that it once went off and was normal no indicator on dash light but only lasted for a minute! Idk if that helps in narrowing down the issue?

LEDs do funky things in vehicles not designed for them. You could have a single diode burnt out in one of the bulbs causing the resistance to be off balance.

Try swapping one bulb at a time to the opposite side and see if the problem follows it, that will tell you which bulb it is without spending any money.

With incandescent bulbs, dim lights is usually a faulty/loose/corroded ground.

Don’t the Escalades have a body control module that run the lights? Is said module under the console? Did somebody spill coffee or coke?

I’d pull the head light assembly out and thoroughly inspected the harness and connectors. Could also be rodents eating the harness and shorting a single strand against another.

Look for ground wires behind the radiator support that lead through the radiator support near the headlights.
