I pulled the stock fog lights off my 06 Sierra, replacing them with some LED pods and added a 22" curved light bar. So far, I'm pretty happy with the out come. I also found a way to run your high beam...
That's the awesomeness of the Sierras is the ability to mount a light bar without blocking airflow to the trans cooler, and that there's round LED lights to mount in place of the factory fogs.
