There is no factory anything for a C7 auxiliary lamp, so I decided to do one..............I like lights.
Disclaimer: This is not a GM product for the C7, to my knowledge, there are no after market auxiliary/fog lamps specifically designed for the C7...........at this time.
Purchased Federal Signal's MicroPulse Wide Angle light (MPSW9-A) to install in the grill. These are basically flashing LEDs for utility/safety type vehicles, but a steady burn can be programmed for my application. I installed the lights to not necessarily light up the road (stock light system does that quite well), but mainly for aesthetics and a more visible presence.
I like the end result and I just have to be different, and besides, I can't stand to be parked next to another's that's exactly like mine.
For me, not a quick job, took me most of the day, slow, but thorough.
