Denali Lights in bumper lights

[05alive]

Next to the turn signals, there is a light in each side. It's not the fog lights, nor the low beams. It doesn't come on with the parking lights. I don't know how to turn it on or what it is for. I don't see them on non Denali trucks. Anybody know what it is?

Answered my own question. It's the Daytime running lights, and they only come on when the truck is in gear.

Start engine, put truck in drive, then jump out and run to the front to check them and make sure they're on.
