Light up Cadillac CTS emblem?

I’m thinking about adding a light-up emblem to my Cadillac CTS and wanted to know if anyone here has done it. How does it look at night—does it really stand out, or is it more subtle? I’m also curious about the installation process. Does it require any special wiring or is it plug-and-play?
I’d prefer something easy to install without messing with the car’s electronics. Any advice or suggestions would be appreciated!
